5ba6db80cc parser: initialize picture variable
When parsing "event 123" (?) a picture is added, without
initializing the picture structure. Thus, a picture with a
random gps location is added.

Use the "empty_picture" initializer to avoid that. Fixes a
Coverity warning.

345959177f Max ceiling precision
We used to round the ceilings for the individual tissues with
%.1f but the maximal (and thus effective) ceiling only with
%.0f. This makes no sense or be rounded up (to the conservative
side).

This commit shows also the maximal ceiling with higher accuracy.

2064ce06cc Fix pO2 for CCR at shallow depths
Even when diving a CCR, the pO2 cannot exceed ambient
pressure. This only makes a difference at shallow depths.

Fix this in the calculation of OTUs and CNS.

This affects some tests that now have slightly different CNS and OTU values.

6b8a07f0d9 Planner: Depth dependent setpoint changes in CCR mode
We had a user request to allow for setpoint changes
at certain depths for CCR deco.

You can now enter a cylinder with name like
"SP 1.4" ('S' and 'P' and ' ' and a float) with
a switch depth and that cylinder is interpreted as
a depth dependent setpoint switch.

This user interface is a hack. But I believe that such
setpoint changes are similar enough to gas switches during
deco and should thus be handled in a simiar manner.

I would be happy to hear ideas how this could be made
less easter eggish.

5b3cb5898f desktop: fold ApplicationState into MainWindow
The application state is a desktop-only thing. The mobile UI
also has its application state, but that is something completely
different.

The last remaining user of the application state was to flag
whether the planner is active. Since this has all been
unglobalized, the ApplicationState structure can be moved
from core to the desktop UI. And there it can be made local
to the MainWindow class.

642d9c80b3 planner: pass in_planner argument to decoMode()
To remove reliance on global state, pass an "in_planner" argument
to decoMode(). Thus, calls to in_planner() can be removed.

This is a more-or-less automated change. Ultimately it would

1ed2f1681a desktop: remove the view-state
There was the "application state", which decided what to show
in the "quadrants" and the "view state" which decided which
quadrant to show. These interacted in a hard-to-grasp way.

The "view state" is used to show the map or dive list in
full screen.

I simply couldn't get these two orthogonal states to interact
properly. Moreover the thing was buggy: If a quadrant was hidden,
the user could still show it, by dragging from the side of the
window, at least under KDE.

To solve these woes, merge the two states into a single
application state. If the widget of a quadrant is set to null,
don't show it. So the four "view states" are now "application
states" where three of the four quadrants are not shown.

This also changes the memory management of the widgets:
widgets that are not shown are now removed from the QSplitter
objects. This makes it possible that the same widget is
shown in *different* quadrants.

While writing this, I stumbled upon a Qt bug, which is known
since 2014:
https://forum.qt.io/topic/43176/qsplitter-sizes-return-0

When restoring the quadrant sizes there was a test whether
the quadrant size is 0. If that was the case, a default size
was set. This seems not to work if the widgets were recently
added. Since this test now always fails, make the quadrants
non-collapsible and thus guarantee that 0 is never saved as
a size.

cd32c280ae undo: remove invalidate_dive_cache() call from make_first_dc()
The make_first_dc() function clones a dive with a certain dive
computer moved to the front. This is used by the
MoveDiveComputerToFront undo command.

make_first_dc() calls invalidate_dive(). However, the undo
command does that by itself on every undo/redo. Thus,
remove the call in make_first_dc().

Aside from consistency, the goal is to move invalidate_dive()
to command/* so that we can be more aggressive about the whole
topic: Store only "const dive *" pointers and thus force any
writing access to explicitly invalidate the dive cache.

235146a95f profile: pass dive to DiveHandler
The DiveHandler shows a context menu where a cylinder can be

Remove this in a step to make the profile reentrant.

The code was quite ominous: instead of simply generating the

with Qt's cumbersome model/view API. All this trampling over

09287809eb profile: move adding of ceiling-violation-event
The profile item that shows the ceilings adds a warning event
if the ceiling is violated. This is very unfortunate.

Improve this situation by adding the event up to the function
that calculates the ceiling. This is still not how it should
be - the display layer should not modify the dive that it
displays.

To make this clear, add a comment that details that this
is a contract between planner and display layer: The planner
uses a dive that can be trampled upon by the profile.
Still, this should be solved differently.

9bfc6d2520 profile: use a parameter to determine planner state
The in_planner() function is incompatible with a reentrant
profile, since it accesses a global variable. In
create_plot_info_new() it is essentially redundant, because
there is a planner_ds (ds = deco_state) parameter that
is used only when in the planner. Therefore use that as
the in_planner indicator: when non-null, the profile is
showing a planned dive.

106f7a8e0e desktop: add statistics widget dummy and application state
Add a new "statistics" application state. In the statistics state
show the statistics widget and the filter in the top quadrants.
The idea is to allow filtering and doing statistics at the same
time.

Sadly, we can't use the filter-widget in different quadrants,
because Qt's ownership model is completely broken / inflexible.
It does not support a widget having different parents and
thus a widget can only belong to one QStackedWidget.

Hiding the map in the statistics view is quite hacky:
Since the view of the quadrants is not determined by the
"ApplicationState", we have to restore the original quadrant
visibility when exiting the stats mode. Therefore, set the
original visibility-state when changing application state.

The MainWindow-quadrant code really needs to be rewritten!

The shown_dives variable was reset by the dive_list code. Arguably,
the filter should keep track of the number of shown dives, so move
the resetting there. This means adding a new "reset()" member function
to the filter and call that instead of "updateAll()" when the core

1037c15b98 mobile: remove DiveObjectHelper code
When editing a dive, a DiveObjectHelper of the unmodified dive
was created to compare the edited with the old values. Since
the DiveObjectHelper is used here only as a pointless wrapper
around the formatting functions, call these functions directly.

However, note that the code is in principle wrong since the
change to the mobile-models, which do not use the DiveObjectHelper.
The real fix would be to reload the data from the model to prevent
going out-of-sync with respect to the formatting routines!

For multiple-choice constraints we use a bit field of type
uint64_t. This means we theoretically support up to 64 items.
Currently use at most seven.

Coverity complained (correctly) that we use the expression
"1 << x" to generate the bitfields. However 1 is a 32-bit
literal on most platforms, which makes this undefined
behavior for x >= 32. Change the integer literal to 64-bit
1ULL.

Moreover, when detecting items with an index >= 64, don't
even attempt to set the according bit, since this is
undefined behavior and the compiler is free to do as it
pleases in such a case.

74d84a959a divecomputer: add device to provided table instead of global table
In the specuial case of suunto, where we may add a device directly
instead of via dive->dc, add the device to the provided table.
The caller will then pass on the new device to the undo system.
This makes downloading finally really undoable (at least I
hope so). So far, the dives and dive sites were removed, but any
new device remained.

However, when setting the device-id via serial, we now have
to check both, the global and the downloaded list of devices.

2bcb3d88a0 divecomputer: add device_table pointer to device_data_t
In one weird case (suunto), the code in libdivecomputer.c
generates a device node directly instead of going the usual
way (setting the data in the dc-structure of the imported
dive). It is unclear to me whether that has to be that way,
as it depends on the chronological order of callbacks to
event_cb() and dive_cb().

Therefore add a device_table pointer to device_data_t
so that the downloader can add the device to this table. This
only adds the pointer, but does not yet use it in the
downloading code.

fd8bd9d5c7 cleanup: use std::string in struct device
struct device is a core data structure and therefore shouldn't use QString.
QString stores as UTF-16 (which is a very questionable choice in itself).
However, the real problem is that this puts us in lifetime-management
hell when interfacing with C code: The UTF-16 has to be converted to
UTF-8, but when returning such a string, this puts burden on the caller
who has to free it. In fact, instead of looping over devices from C-code
we had a callback that sent down temporary C-strings with qPrintable.

In contrast, std::string is guaranteed to store its data as
contiguous null-terminated and C-compatible strings. Therefore,
replace the QString by std::string. Keep the QString just in
one place that formats a hexadecimal number to avoid any
potential change.

The disadvantage of using std::string is that it will crash
when constructed with a NULL argument, consistent with C-style
functions such as strcmp, etc. Arguably, NULL is different
from the empty string even though we treat both as the same.

2e5913d2ba core: fix detection of duplicate device names
Recently (c9b8584bd2) the sort criteria of the device-table
was changed from  (model/id) to (id/model). However, that
messed with the detection of duplicate device names: there,
the code searched for the first element greater or equal
to (model / 0).

With the reversal of the sort criteria, this would now
always give the first element.

Therefore, do a simple non-binary search, which is much
more robust. The binary search was a silly and pointless
premature optimization anyway - don't do such things
if not necessary!

Since only one place in the code search for existence
for a model-name, fold the corresponding function into
that place.

Moreover, change the code to do a case-insensitive compare.

call_for_each_dc(). This sorts the table by device-id. It
is unclear whether this is needed - since currently all it
does is make sure that the devices have a fixed order in XML

In any case, this means that the table had to be copied and
sorted in call_for_each_dc(). Since the frontend now does
its own sorting, we can just keep the core table sorted
as it needs it. This in turn will ultimately make it possible
to replace the callback by a simple loop.

6729428b6a core: improve merging of cylinders pressures
When merging cylinders pressures derived from samples were taken
as maximum of the start and minimum of the end pressure, which
makes sense, since we believe that this is the same cylinder.

However, for manually entered pressures, this was not done.

Moreover, when one dive had manual pressures and the other only
pressure from samples, the manual pressure was taken. However,
that could have been the wrong one, for example if the end
pressure was manually set for the cylinder of the first part of
the dive, but not the last.

Therefore, improve merging of manuall set pressures in two ways:
1) use maximum/minimum for start/end pressure
2) if the pressure of one cylinder was manually set, but not for
   the other, complete with the sample pressure (if that exists).

We keep track of device, i.e. distinct dive computers with id in the core.

Notably it defined a "DiveComputerNode" when this is something very different
from "struct dive_computer", the latter being the dive-computer related
data of a single dive.

Since the whole thing is defined in "device.h" and the function to create
such an entry is called "create_device_node", call the structure "device".
Use snake_case for consistency with the other core structures.

Moreover, call the collection of devices "device_table" in analogy

ec431155a9 filter: implement filtering for gas mixes
This adds filter constraints for numerical filtering for gas-mixes.
Currently, this does a "match any" kind of search, which means that
a dive is filtered if any of its cylinders matches.

We should also implement "all-of" and "none-of" modes for cylinder
filtering.

d8f35711ff membuffer: be defensive about bad C library vsnprintf implementations
Dirk reports that some Windows users have had odd corruption in the
commit messages in the cloud storage.  They make no sense at all unless
there is some very weird Windows library bug.

The prime suspect is 'vsnprintf()' returning a negative error when the
target buffer is too small (rather than the proper "this is how much
space it would need").  That is a very traditional C library bug that I
thougth had been fixed everywhere, but there doesn't really seem to be a
lot of other likely causes.

So let's make our membuffer code be defensive against bad libraries that
return negative error numbers from vsnprintf.

4608beaee4 Android BLE discovery: use discovery agent
Android can't scan for classic BT devices, so when BT support was first
added, we simply didn't use the discovery agent at all and relied on the
list of paired BT devices provided by Android.

This still worked fine for a lot of BLE devices that allowed 'bonding'
with the Android device - similar to pairing. But some BLE devices (like
the Shearwater Peregrine) don't support bonding and so our Android code
didn't see them at all.

With this commit we start a BLE only scan on Android to add to the list
of already paired devices.

3bfd448b59 filter: implement saving of filter presets to git repositories
On the mailing list it was decided that users might want to
move their filter presets across computers via the cloud.
Notably, in the future one might access statistics on mobile and
these might by controlled by filter presets.

The git save routines use the same string formatting as the
XML save routines. The string formatting is found in
core/filterconstraint.cpp. Thus, duplication of code and
inconsistencies should be minimized.

Each filter preset is saved into a file in the "02-Filterpresets"
folder in the root of the git repository.

Each file consists of one "name" line, zero or one "fulltext" line
and zero or more "constraint" lines.

The modes, types and the actual payload is controlled via attributes.
Thus, a preset file might look like this:

name "test"
fulltext mode="substring" query="clown"
constraint type="location" stringmode="starstwith" data="mafia"
constraint type="sac" rangemode="range" negate data="5000,10000"

41cf83583d filter: load filter presets from XML files
This is a bit painful: since we don't want to modify the filter
presets when the user imports (as opposed to opens) a log,
we have to provide a table where the parser stores the presets.
Calling the parser is getting quite unwieldy, since many tables
are passed. We probably should introduce a structure representing
a full log-book at one point, which collects all the things that
are saved to the log.

Apart from that, this is simply the counterpart to saving to XML.
The interpretation of the string data is performed by core
functions, not the parser itself to avoid code duplication with
the git parser.

448bc5600b filter: implement saving of presets to XML file
Users might want to move their presets with there log-file. Therefore,
save the presets to the log. The alternative would be to save them
to the preferences. However, on the mailinglist it was decided that
moving the presets to a mobile device is a wanted feature.

The XML saving code has a rather reasonable interface, therefore
this turned out to be pretty easy to implement.

The filter presets are saved into a
<filterpresets>
 ...
</filterpresets>
block

Each individual preset is saved into a
 <filterpreset name='...'>
    ...
 </filterpreset>
Block with a unique name attribute.

Each preset contains zero or one fulltext and zero or more constraint entries.
The type and mode(s) are controlled by attributes, the "payload" is saved in
the block. Note that all the formatting is done by functions in core/filterconstraint.c
and not the parser itself.

A preset in the XML file might look like this:

 <filterpreset name='test1'>
  <fulltext mode='startswith'>Train</fulltext>
  <constraint type='planned'>0,0</constraint>
  <constraint type='sac' range_mode='range' negate='1'>5000,10000</constraint>

634152ae43 filter: add filter constraint object to the core
Adds a filter constraint object to the core, which represents one
constraint the user can filter dives with. The plan is to write these
constraints to the XML and git logs. Therefore, this code is written
in C-style except when it comes to handling strings and dates, which
is just too painful in plain C.

There is one pointer to QStringList in the class, though when compiled
with C, this is simply transformed into a pointer to void. Granted,
that smells of an ugly hack. However it's more pragmatic than
self-flaggelation with C string and list handling.

A filter constraint is supposed to be a very general thing, which can
filter for strings, multiple-choice lists, numerical ranges and date
ranges.

Range constraints have a range mode: less-or-equal, greater-or-equal
or in-range. Text constraints have a string mode: startswith, substring
or exact.

All the data are accessed via setter and getter functions for
at least basic levels of isolation, despite being written with
a C-interface in mind.

a7ca27d071 Prefer "GPS1" for divecomputer download dive site resolution
I think we only have one dive computer that supports GPS data right now:
the Garmin Descent Mk1.  It reports the dive coordinates as "GPS1" and
"GPS2" for the entry point and exit point respectively.

Often GPS1 is missing, because the dive computer may not have gotten a
GPS lock before the diver jumped into the water, so when that happens
we'll use GPS2 for the dive site location.  But when GPS1 exists, we
should prefer that.

And that's what we already did in logic in dc_get_gps_location(), but
for the initial dive site created at download time, we just picked any
divecomputer reported string that started with "GPS".  And since GPS2 is
reported after GPS1 by the Garmin Descent, it would end up overwriting
the entry point that we _should_ have preferred.

Add the same kind of "explicitly prefer GPS1" logic to the initial dive
download case as we already had elsewhere.

It turns out that contrary to what the documentation states, a few languages
are still only using the 'qt' translation. But those exist for all languages,
so we need to first search for the 'qtbase' translations, and only if that
fails do we try to load the 'qt' translations.

And even that will fail for languages in which Qt simply isn't localized (like
Dutch).

To make the code more readable, the check for 'US English' was moved earlier as
there is no point to look for a Qt translation for that (simply doesn't exist).

1ed8cb373f translations: use the right Qt translations and try harder to find them
We were still using the 'qt' translations instead of 'qtbase' as we should have
been using since forever - it's a little unclear from reading the documentation
when in the Qt5 life cycle this happened, but definitely several years ago.
These are the strings used in situations where Qt already provides us with text
(e.g., the entries in the 'Subsurface' menu on Mac, or the button labels in
many dialogs).

Additionally we didn't try hard enough to find those translations in cases
where they are bundled with the app; so basically all scenarios except for
Linux distro specific packages or 'build from source' on macOS or Linux were
not going to work, even after addressing the qt->qtbase conversion.

But of course the developers pretty much all fall into those last two
categories. Still, I cannot believe we never fixed this in all those years...

To make it more obvious if we still aren't finding the Qt translations this
commit also makes that warning be shown in all cases, not just when running in
verbose mode.

a01ab81713 cleanup: fold core/divecomputer.cpp into core/device.c
core/device.h was declaring a number of functions that were related
to divecomputers (dcs): creating a fake dc for manually entered dives
and registering / accessing dc nicknames. On could argue whether
these should be lumped together, but it is what it is.

However, part of that was implemented in C++/Qt code in a separate
core/divecomputer.cpp file. Some function therein where only
accessible to C++ and declared in core/divecomputer.h.

All in all, a big mess. Let's simply combine the files and
conditionally compile the C++-only functions depending on
the __cplusplus define.

Yes, that means turning device.c into device.cpp. A brave soul
might turn the C++/Qt code into C code if they whish later on.

6ea0cc62b8 desktop: refine auto-fill of weights
In a previous commit, auto-filling of weight based on type was
changed to be only performed if the user hadn't already set a
weight, by testing for weight=0.

However, when the user edited the type and tabbed back and forth,
that counted as an edit and therefore the weight would not
change anymore.

To refine this, introduce an "auto_filled" flag to the weightsystem,
which is set if the weight is automatically filled and cleared if
the weight is edited. Update the weight if it was zero *or* auto-filled.

The flag is not saved to disk, but that should be acceptable. If the
user saves and reloads, we can assume that they meant the weight
to be set to the default value.

This adds a common macro to convert salinity (which is
given as a density in terms of g per 10l) to a specific
weight with units of mbar / mm = bar / m that is used
to translate between pressures and depths.

The weired factor of 10 (from the unusual unit of salinity)
is included in the macro. It is there for historical reasons,
as it goes back to 05b55542c8 from 2012 where it was introduced
in code for downloading from Uemis dive computers.

d404aa767f [Bug #2934] Geo Lookup - support for remote dive sites
Some remote dive sites have no populated places (towns, cities)
nearby. For such sites, we now fall back to looking up
unpopulated place names, such as the reef or island name.

Also some code refactorisation:
the actual network access is now encapsulated in its own
function removing some duplicated code handling in the
reverseGeoLookup function and making it more readable.

Furthermore, reverseGeoLookup() was completely refactored as
most of its functionality was due to legacy requirements; the
current code-base only calls this function from a single
location and only with an empty taxonomy_data object. This
makes the function more focussed and much simpler and more
readable.

Finally, a resource leak in reverseGeocde introduced in
4f3b26f9b6 was fixed.

The dive information is read from the headers_dive table.
The dive_data table is then queried for each dive to get samples.

The seac action computer is the only current supported computer
by the seacsync program. It only supports two gas mixes, so the
parser will toggle between two cylinders whenever it detects a
change in the active O2 mix.

Dive start time is stored in UTC with a timezone offset.

c888a1727e DataTrak import: Add support for WLog extensions.
WLog is a Win32 based ancient shareware program whose target was:
1) fully support divelogs coming from DataTrak (DOS or Win)
2) fill some meaningful data which wasn't supported by Uwatec software
3) have a more user-friendly GUI than Datatrak had
The problem achieving goals 1) and 2) at the same time was solved by
adding a complementary file with .add extension and - mandatory - same
base name than .log file (including directory tree).

This .add file has a fixed structure composed of a 12 bytes header,
including file type check and Nº of dives following; then a fixed 850
bytes size for each dive in the log file. Data fields size and position
are fixed inside these blocks and heavily zero padded, so they are easy
to parse.

A serious restriction imposed to the WLog user was *Do not edit the logs
with other software than Wlog*; this was due the order of dives in .log
file being the same than the order of dives in .add file. Thought you
could show a WLog divelog in Datatrak, editing it resulted in mixing all
extended data for dives following the edited one.
Thus, we have to trust files are correct and is to the user ensure this
is so. If extended data are mangled, they are mangled in WLog too and we
are not trying to fix the mess, just importing.

On the technical side, we try to be smart about tank names as neither
DataTrak nor WLog record them. So we just take the first tank in users
list matching the volume recorded in WLog.
For weights we add a translatable "unknown" string as an empty string
results in weight not being shown in subsurface-mobile (which could be a
reportable issue, BTW).

get_cylinder(d, i) is more readable than d->cylinders.cylinders[i].
Moreover, it does bound checking and is more flexible with respect to

This patch unifies the accesses by consistently switching to get_cylinder().
The affected code is in C++ and accesses the cylinder as reference or

getFormattedCylinder() is a helper function to format a list

would instead be written as "unkown".

The reason was the old statically sized cylinder array,
where it wasn't clear if a cylinder was actually in use.

This became obsolete when switching to a variable size
cylinder array. Firstly, all cylinders in the array were added
by the user. Secondly, we now also support dives without
cylinders, i.e. the first cylinder is not any different from
the rest.

Thus, remove the logic and format any cylinder without
description as being of type "unknown".

77a11400a1 Fix event merging when merging dives
The merge_events() function was subtly and not-so-subtly broken in a
couple of ways:

 - in commit 8c2383b49 ("Undo: don't modify source-dives on merge"), we
   stopped walking the event list after we merged the first event from a
   dive when the other dive computer had run out of events.

   In particular, this meant that when merging consecutive dives, the
   second dive only had the first event copied over to the merged dive.

   This happened because the original code just moved the whole old list
   over when there was nothing left from the other dive, so the old code
   didn't need to iterate over the event list. The new code didn't
   realize that the pointer movement used to copy the whole rest of the
   list, and also stopped iterating.

   In all fairness, the new code did get the time offset right, which
   the old code didn't. So this was always buggy.

 - similarly, the "avoid redundant gas changes" case was not handled for
   the "we ran out of events for the other dive computer" case.

This fixes both issues.

The last time those changed, we forgot to update serial_ftdi. In that change
set_latency had been removed from libdivecomputer and poll and ioctl had been
added. This caused the callbacks to no longer be aligned correctly and the

pointers, leading to crashes.

Instead of the fragile assumptions about order and type of function pointers,
use named initializers. And while we are at it, fix that for the bluetooth

8b478a969d git-storage: add global flag to indicate successful cloud sync
This may seem like a bit heavy handed as it adds more global state, but given
the number of ways in which attempts to sync with the cloud can fail it seems
much more reliable to claim success in the spots where we actually know that we
have successfully synced with the remote server. Transporting that information
back through the various call chains turned out to be very disruptive and ugly,
so I went with global state instead.

Whenever we access cloud storage (or any git repo), we always first check if it
actually is a git repo by calling is_git_repository() - so this is the perfect
spot to initialize the variable to false.

And there are only two spots where we either clone the remote repo
(create_local_repo()) or update the remote with the (potentially merged) local
changes (check_remote_status()). So those are the two places where we set the
variable to true.

e91c252093 BLE: add list of known good/bad BLE GATT services
We've tried to do this "automagic" service discovery, and it mostly
works, but then occasionally it doesn't.

Making things worse, I think different platforms end up enumerating
services differently, so our "pick the first service that looks like it
might be a serial service" ends up working on some platforms, but not
necessarily on others.  Because "first" might be different.

So start a list of known good/bad services - and fall back to the old
logic when you can't decide reliably.

This fills in juat a few cases that I can easily check myself, and the
"details" field for them may be incomplete.  For example, I know Nordic
Semiconductor has their vendor-specific UUIDs, and they can be found in
different devices, so calling them "Nordic UART" and "Nordic Flash"
services makes sense.

But the "Scubapro i770R" service? It might indeed be specific to the
Scubapro i770R.  Or it might be a general service UUID that Pelagic
uses.  Or it might be the service UUID of a particular chip, and found
in dive computers from other designs too (and not necessarily in all
i770R's either).

So this is a preliminary first stab at this, and I'm sure we'll extend
the list and possibly improve on the explanations.

If there isn't a name, don't add a leading space in order to make it easy to

658089d763 core/bt: match DC descriptor in lower case
This fixes a rather subtle bug.

In btdiscovery.cpp we are detecting dive computers based on their BT name and
are setting up product+vendor as the key for that lookup. QMap always uses case
sensitive comparisons and a tiny inconsistency snuck into our code.
libdivecomputer names for the Aqualung dive computers i200C / i300C / i550C end
in an upper case C (as matches the official branding), but in btdiscovery.cpp
we have those names with lower case c. And therefore didn't recognize these
dive computers.

Obviously this is easy to fix by fixing those three strings, but I decided that
it was silly to set ourselves up for similar oversights in the future. So
instead I switched the matching of the descriptor to simply be allways all
lower case.

fb6210a99a cleanup: invert control-flow when resetting the core structures
To reset the core data structures, the mobile and desktop UIs
were calling into the dive-list models, which then reset the
core data structures, themselves and the unrelated
locationinformation model. The UI code then reset various other
things, such as the TankInformation model or the map. . This was
unsatisfying from a control-flow perspective, as the models should
display the core data, not act on it. Moreover, this meant lots
of intricate intermodule-dependencies.

Thus, straighten up the control flow: give the C core the
possibility to send a "all data reset" event. And do that
in those functions that reset the core data structures.
Let each module react to this event by itself. This removes
inter-module dependencies. For example, the MainWindow now
doesn't have to reset the TankInfoModel or the MapWidget.

Then, to reset the core data structures, let the UI code
simply directly call the respective core functions.

d787e8812c profile: for maxtime calculation include the sample after the last event
When plotting profiles with surface segments, there were strange
artifacts. As we found out with Robert, these were due to the fact
that the calculated maxtime was set to the last event which is just one
second inside the surface segment. This terribly confused the profile
code. For example, it didn't properly allocate samples for the surface
segment.

Thus, when calculating maxtime, consider the last sample beyond the
last event.

ffc3e598fa core: create fake cylinder at end of cylinder table (hack!)
When we had fixed-sized cylinder arrays, the planner used the last
empty cylinder for "surface air". This was not recognized by the UI
as a separate cylinder, because "empty cylinder" was the sentinel for
the end of the table. The conversion to dynamically sized cylinder
tables broke this code: everytime the surface segment is changed,
a new dummy cylinder is added, which is visible in the UI.

As a very temporary stop-gap fix, emulate the old code by creating
a cylinder and then setting the end-of-table to before that cylinder.
This means that we have to loosen the out-of-bound checks.

That's all very scary and should be removed as soon as possible.

2) we have to work on arbitrary divecomputers
3) we don't work with copies of events

Therefore, create a new remove_event_from_dc() function that
does all that. Moreover, make the event argument to remove_event()
const to (slightly) point out the difference in the API.

string literal. Since the caller expects a copied string
and takes ownership of that string, it will ultimately

Concrete example: a log with erroneous cylinder data was opened
getting such an empty string literal as description. On closing or
syncing with the cloud, the dive is freed, leading to a free
of the string literal -> crash.

a34a81d120 android usb serial: Prepare device / driver select
This commit contains the serial_android_usb part of the changes proposed
in issue #2657.

What's implemented:
- A data structure that contains all the data that can be used to
  describe an usb device (including user-facing string).
- A function to get a list of all attached usb devices (optionally with
  selectable driver class).
- Changes in the serial_android_usb_open-function and in the Java part
  to use the information about the usb device and optionally selected
  driver when connecting.

This commit keeps compatibility with the current UI-Code in the case
that only one USB-Device is connected. If two devices are connected,
only the first one is tried.

There are still some small things to do:
- Change the user-facing string to something more descriptive.
- Parts which aren't uesd anymore when the UI-Part is implemented are
  simply marked as obsolete (to keep compatibility for now).

But generally it seems to work.

5e89d81d9d iostream: fix incorrect rfcomm error case when writing
This is the exact same case as the previous commit, just for the writing
side.

Once again, it's the subsurface rfcomm iostream code that can return
DC_STATUS_SUCCESS with a byte count of zero when something goes wrong
with the write.

And once again, our libdivecomputer iostream code didn't try to be
robust and protect itself from that case.

The fix is equivalent, although slightly simpler, since the write side
doesn't have the whole timeout issue.

4ee4bbdb58 iostream: fix incorrect rfcomm error case when reading
We had two independent bugs here, both of which needed to fire for this
to cause a problem.  This fixes both of them.

The first bug was that our rfcomm code would return DC_STATUS_SUCCESS
with a zero-sized read when a timeout happened, or when the rfcomm
socket had disconnected.  That makes absolutely no sense.  We should
return DC_STATUS_TIMEOUT on timeout, and DC_STATUS_IO if the socket has
disconnected without any data.

The fix to this is to make the whole rfcomm iostream read logic much
simpler: there's no need to loop at all for partial results, because the
libdivecomputer iostream side will do the loop for us (and handle
partial results much better: it knows if the target backend can handle
those partial results or not).

The second bug was in our libdivecomputer iostream read() function,
which reacted very badly to this bad return value.  This updates our
libdivecomputer branch to one that is more careful about things.

data here, but on FTDI the chip seems to return whatever is currently in
the buffer (so 0 bytes if the buffer is empty). This different behaviour
should be mitigated by the changes by this commit.

6e38f85ba7 usb-serial-for-android: Implementation
Implement the libdivecomputer API in Java and create C/JNI translation
layer.

[Dirk Hohndel: whitespace harmonization - yes, some of this is Java,
               this still makes it much easier to read for me;
               also changed the FTDI conditional compilation to make
               sure we can still use that for mobile-on-desktop if
               necessary]

97e26fd51b mobile: allow disabling BT support from the command line
This is a quick hack to reduce the noise in the log file when chasing other
bugs. Maybe this should not be enabled on release builds, but right now I don't
think the harm that having this in would do.

62adc24d15 Core: don't return invalid cylinders from explicit_first_cylinder()
For reasons which I don't yet understand, when plotting a dive
whose first cylinder is not cylinder 0 and then plotting a dive
with only one cylinder, it can happen that for the latter
explicit_first_cylinder() returns an erroneous value.

This is due to the way in which we copy the dive to be plotted
to displayed_dive.

For now, make sure that no invalid cylinder is returned to avoid
crashes. This will have to be changed anyway, since this is very
fundamentally not thread-safe and inefficient.

8a0eecfd5e cleanup: make version_printed variable static and local to function
The version_printed variable is used to print version information
only once. It was a global variable, but never used outside of
its function. Therefore, move it into the function and make it
static. Since this is a plain old datatype (POD), it makes no
no difference whatsoever whether the static variable is in block
scope or not. Indeed, it is initialized in the data segment). Well,
we are in C mode and therefore everything has to be POD by definition.
I tested this on gcc and clang.
