To access a QMap<> entry, the value() function is used with a sentinel
as default value. If the sentinel is returned, the code assumes that
the searched for entry doesn't exist.
Make this code more idiomatic by using an iterator and testing for
end().
This fixes a compiler warning, because only one of the elements of
the sentinel was initialized, but the remaining elements were
copied. Harmless, because the code would exit early if it found
the sentinel. Still not nice.
While redoing this function, the entry-not-found message was improved
(adding of function name, space between massage and timestamp) and
elevated from debug to warning level.

In hindsight a very simple bug to fix, but it requires some
knowledge on the inner workings of our git storage. The changes
on merge of dive sites were simply not saved (completely) because
the git storage code has a cache that we need to invalidate
selectively (ie. for the dive we just gave a new dive site uuid)
to get things finally embedded in the overall commit.
The main reason this bug went unnoticed for more than 2 years is
that most people use the XML/SSRF format (where this problem is
non exsistent), and dive site merging is probably not a very
much used feature either.

Commit 46004c39e2 introduces a new field in the logbook outputs
(depth of a cylinder). While in XML the depth unit is stored with a space
between value and unit (m), in our git storage, the unit m is without
space. As the git storage parser uses a space to separate individual
key/value pairs, the erroneously saved space results in parsing warnings
when opening the logbook.
The unwanted space is normally saved just after download of a new dive
from the dive computers, so all desktop-git-storage uses are affected,
and more worrying, mobile beta users.

Internal floating point (FP) calculations should be performed using double
unless there is a very good reason. This avoids headaches with conversions.
Indeed, the vast majority of FP calculations were already done using double.
This patch adapts most remaining calculations. Not converted where things
that were based on binary representations and variables which weren't used
anyway.
An analysis of all instances follows:
core/plannernotes.c, l.404:
This was a comparison between two floats. On the left side, first an integer
was cast to float then multiplied with and integer and divided by a constant
double. The right hand side was an integer cast to a float. Simply divide by
1000.0 first to convert to double and continue with calculations. On the right
hand side, remove the cast, because the integer will be implicitely cast to
double for comparison. This conversion actually emits less instructions,
because no conversion to double and back is performed.
core/planner.c, l.613:
Same analysis as previous case.
subsurface-desktop-main.cpp, l.155:
A local variable representing the version OpenGL version. Turn this into
integer logic. Not only does this avoid dreaded FP rounding issues, it also
works correctly for minor version > 10 (not that such a thing is to be
expected anytime soon).
abstractpreferenceswidget.[h/cpp]:
A widget where the position is described as a float. Turn into double.
desktop-widgets/divelogexportdialog.cpp, l.313:
total_weight is described as float. Use double arithmetics instead. This
instance fixes a truncation warning emitted by gcc.
The function isCloudUrl() was only called in one place, parse_file().
But, isCloudUrl() could only return true if the filename was of the
git-repository kind (url[branch]). In such a case, control flow would
never reach the point where isCloudUrl() is called, since
is_git_repository() returns non-NULL and the function returns early.
Therefore, remove this function. Moreover, adapt the affected if-statement
by replacing "str && !strcmp(str, ...)" with the more concise
"same_string(str, ...)".

Each preferences object owns its string members. In three cases, pointers
were copied instead of strings, leading to (in the best case) dangling
pointers if the user edited values:
1) In the GET_TXT macro in core/prefs-macros.h
2) In the PreferencesDialog::defaultsRequested() method
3) In main() of the mobile version
This patch fixes these issues, by using copy_string() or copy_prefs()
as appropriate.
The only reason that the old code didn't crash regularly is that the
default_prefs object was only used at startup and defaultsRequested()
is (at the moment?) dead code.

In the old implementation there were two static C-style strings, filename
and path, which were initialized to NULL and filled on first call of
the function (i.e. singletons).
There is no sense in having two static variables indicating whether
this function was called previously. Moreover, there is no point
in remembering filename accross function calls, because it is not
used once path is set to a non-NULL value.
Therefore, make the filename variable non-static and calculate it only on
first invocation (as indicated by a NULL path). Moreover, free() the filename
variable after its use to fix a memory leak of the old code.
The windows code is slightly different in that the temporary filename is
not dynamically allocated.

This tries to remove subtle ownership issues. When copying preferences

Stefan Fuchs points out that sometimes you get cylinder duplication when
you merge dives, particularly with a planned dive. For example, if we
had different manual pressures in the two different dives, the cylinders
will be kept separate.
But that also means that we don't want to plot the pressures from those
other cylinders that came from another dive and are now associated with
another dive computer.

current_dc is a macro that determines the dive computer
based on the current dive number. When the planner is started
from an emtpy dive list, the dive number ends up being -1 and
that doesn't produce a valid dive computer. Use the divecomputer

can also be used in two other places. Without this patch, the

When changing the date/time of a dive in the planner the dive may end
up in a totaly new position in respect to date/time of other dives in
dive list table. It can be moved to the past or the future before or after
other existing dives. It also could overlap with an existing dive.
This change enables identification of a new "virtual" dive list position
and based on this starts looking for previous dives.
Then it (as before the change) does init the deco calculation with any
applicable previous dive and surface interval.
If some of these applicable dives overlap it returns a neg. surface time
which is then used in the planner notes to prohibit display of results.

import:
case POSEIDON_PRESSURE:

+ sample->pressure[0].mbar = lrint(val * 1000);

case POSEIDON_O2CYLINDER:
- sample->o2cylinderpressure.mbar = lrint(val * 1000);
+ sample->pressure[1].mbar = lrint(val * 1000);
break;
which was ObviouslyCorrect(tm).
But as so often is the case, obvious doesn't actually exist. The old
"o2cylinderpressure[]" model had an implicit sensor associated with it,
and that implicit sensor mapping wasn't obvious, and didn't get fixed.
It turns out that the way the Poseidon sensor mapping works, the O2
cylinder is cylinder 0, and the diluent cylinder is cylinder 1, so just
use the add_sample_pressure() helper to set both sensor index and
pressure value.
And since we now do all the sensor indexing right, we can also get rid
of some manual cylinder sample pressure code, because the generic dive
fixup will just DTRT. It used to screw up because the diluent sensor
number was wrong before, and the import code tried to work around that

So the manual gas pressure case keeps showing issues, and in many ways it
really is a fairly complex thing, since it needs interpolation of the
intermediate pressures - possibly over several gas changes.
So you might have beginning and ending pressures for one cylinder, but
then use another cylinder in between.
We've historically got all the code to do this, but the big rewrite for
multiple cylinder pressures didn't get all the details right, and so
here's a few more fixes for the case that was shown by a dive by Robert
Helling. Hopefully we're approaching the old code situation, except now

The core to plot manually entered pressures without any sample data did
the obvious thing: it ended the pressures at the end of the dive as
indicated by the last sample.
However, that obvious thing didn't actually work, because sometimes the
last sample is long long after the dive has actually ended, and we have
no plot_info data for that.
This depends on the dive computer used: most dive computers will not
report samples after the end (even if they may internally remember them
in case the diver just came up to the surface temporarily), but some
definitely do. The OSTC3 is a prime example of that.
Anyway, the code was fragile and wrong - even if passed a time past the
end of the plot_info data, "add_plot_pressure()" should just have
associated that with the last entry instead. Which also allows us to
simplify the whole endtime logic entirely, and just use INT_MAX for it.
Gaetan Bisson's test-case also showed another oddity: we would plot the
gas pressure even for cylinders that had no has use (ie beginning and
ending pressures were the same). That's kind of pointless in so many
ways. So limit the manual pressure population to cylinders that
actually have seen use.

So it should now DTRT even for sidemount diving (assuming you had the
same gas in the sidemount cylinders).
NOTE! We could just do the SAC rate over *all* the gases you have
pressures for, and maybe that's the right thing to do. The ones you are

In addition, for good performance (to avoid looping over the event list
over and over and over again) it maintains a pointer to the next gas
switch event, and the previous gas. Those need to be initialized to
NULL by the caller, so the standard use-case pattern basically looks
like this:
struct gasmix *gasmix = NULL;
struct event *ev = NULL;
loop over samples or plot events in increasing time order: {
...
gasmix = get_gasmix(dive, dc, time, &ev, gasmix);
...
}
and then you can see what the currently breathing gas is at that time.
If for some reason you need to walk backwards in time, you can just pass
in a NULL gasmix again, which will reset the event iterator (at the cost
of now having to walk all the events again).

This finally handles multiple cylinder pressures, both overlapping and
consecutive, and it seems to work on the nasty cases I've thrown at it.
Want to just track five different cylinders all at once, without any
pesky gas switch events? Sure, you can do that. It will show five
different gas pressures for your five cylinders, and they will go down
as you breathe down the cylinders.
I obviously don't have any real data for that case, but I do have a test
file with five actual cylinders that all have samples over the whole
course of the dive. The end result looks messy as hell, but what did
you expect?
HOWEVER.
The only way to do this sanely was
- actually make the "struct plot_info" have all the cylinder pressures
(so no "sensor index and pressure" - every cylinder has a pressure for
every plot info entry)
This obviously makes the plot_info much bigger. We used to have
MAX_CYLINDERS be a fairly generous 8, which seems sane. The planning
code made that 8 be 20. That seems questionable. But whatever.
The good news is that the plot-info should hopefully get freed, and
only be allocated one dive at a time, so the fact that it is big and
nasty shouldn't be a scaling issue, though.
- the "populate_pressure_information()" function had to be rewritten
quite a bit. The good news is that it's actually simpler now, although
I would not go so far as to really call it simple. It's still
complicated and suble, but now it explicitly just does one cylinder at
a time.
It *used* to have this insanely complicated "keep track of the pressure
ranges for every cylinder at once". I just couldn't stand that model
and keep my sanity, so it now just tracks one cylinder at a time, and
doesn't have an array of live data, instead the caller will just call
it for each cylinder.
- get rid of some of our hackier stuff, like the code that populates the
plot_info data code with the currently selected cylinder number, and
clears out any other pressures. That obviously does *not* work when you
may not have a single primary cylinder any more.
Now, the above sounds like all good things. Yeah, it mostly is.
BUT.
There's a few big downsides from the above:
- there's no sane way to do this as a series of small changes.
The change to make the plot_info take an array of cylinder pressures
rather than the sensor+pressure model really isn't amenable to "fix up
one use at a time". When you switch over to the new data structure
model, you have to switch over to the new way of populating the
pressure ranges. The two just go hand in hand.
- Some of our code *depended* on the "sensor+pressure" model. I fixed all
the ones I could sanely fix. There was one particular case that I just
couldn't sanely fix, and I didn't care enough about it to do something
insane.
So the only _known_ breakage is the "TankItem" profile widget. That's
the bar at the bottom of the profile that shows which cylinder is in
use right now. You'd think that would be trivial to fix up, and yes it
would be - I could just use the regular model of
firstcyl = explicit_first_cylinder(dive, dc)
.. then iterate over the gas change events to see the others ..
but the problem with the "TankItem" widget is that it does its own
model, and it has thrown away the dive and the dive computer
information. It just doesn't even know. It only knows what cylinders
there are, and the plot_info. And it just used to look at the sensor
number in the plot_info, and be done with that. That number no longer
exists.
- I have tested it, and I think the code is better, but hey, it's a
fairly large patch to some of the more complex code in our code base.
That "interpolate missing pressure fields" code really isn't pretty. It
may be prettier, but..
Anyway, without further ado, here's the patch. No sign-off yet, because I
do think people should look and comment. But I think the patch is fine,
and I'll fix anythign that anybody can find, *except* for that TankItem
thing that I will refuse to touch. That class is ugly. It needs to have
access to the actual dive.
Note how it actually does remove more lines than it adds, and that's
despite added comments etc. The code really is simpler, but there may be
cases in there that need more work.
Known missing pieces that don't currently take advantage of concurrent
cylinder pressure data:
- the momentary SAC rate coloring for dives will need more work
- dive merging (but we expect to generally normally not merge dive
computers, which is the main source of sensor data)
- actually taking advantage of different sensor data from different
dive computers
But most of all: Testing. Lots and lots of testing to find all the
corner cases.

This does both the XML and the git save format, because the changes
really are the same, even if the actual format differs in some details.
See how the two "save_samples()" routines both do the same basic setup,
for example.
This is fairly straightforward, with the possible exception of the odd
sensor = sample->sensor[0];
default in the git pressure loading code.
That line just means that if we do *not* have an explicit cylinder index
for the pressure reading, we will always end up filling in the new
pressure as the first pressure (because the cylinder index will match the
first sensor slot).
So that makes the "add_sample_pressure()" case always do the same thing it
used to do for the legacy case: fill in the first slot. The actual sensor
index may later change, since the legacy format has a "sensor=X" key value
pair that sets the sensor, but it will also use the first sensor slot,
making it all do exactly what it used to do.
And on the other hand, if we're loading new-style data with cylinder
pressure and sensor index together, we just end up using the new semantics
for add_sample_pressure(), which tries to keep the same slot for the same
sensor, but does the right thing if we already have other pressure values.
The XML code has no such issues at all, since it can't share the cases
anyway, and we need to have different node names for the different sensor
values and cannot just have multiple "pressure" entries. Have I mentioned
how much I despise XML lately?

Also add another helper: "legacy_format_o2pressures()" which checks the
sample data to see if we can use the legacy format, and returns the o2
pressure sensor to use for that legacy format.
Because both the XML and the git save format will need a way to save the
compatible old-style information, when possible, but save an extended

This tries to sanely handle the case of a dive computer reporting
multiple cylinder pressures concurrently.
NOTE! There are various "interesting" situations that this whole issue
brings up:
- some dive computers may report more cylinder pressures than we have
slots for.
Currently we will drop such pressures on the floor if they come for
the same sample, but if they end up being spread across multiple
samples we will end up re-using the slots with different sensor
indexes.
That kind of slot re-use may or may not end up confusing other
subsurface logic - for example, make things believe there was a
cylidner change event.
- some dive computers might send only one sample at a time, but switch
*which* sample they send on a gas switch event. If they also report
the correct sensor number, we'll now start reporting that pressure in
the second slot.
This should all be fine, and is the RightThing(tm) to do, but is
different from what we used to do when we only ever used a single
slot.
- When people actually use multiple sensors, our old save format will
start to need fixing. Right now our save format comes from the CCR
model where the second sensor was always the Oxygen sensor.
We save that pressure fine (except we save it as "o2pressure" - just
an odd historical naming artifact), but we do *not* save the actual
sensor index, because in our traditional format that was always
implicit in the data ("it's the oxygen cylinder").
so while this code hopefully makes our libdivecomputer download do the
right thing, there *will* be further fallout from having multiple
cylinder pressure sensors. We're not done yet.

Because of how we traditionally did things, the "o2pressure" parsing
depends on implicitly setting the sensor index to the last cylinder that
was marked as being used for oxygen.
We also always defaulted the primary sensor (which is used for the
diluent tank for CCR) to cylinder 0, but that doesn't work when the
oxygen tank is cylinder 0.
This gets that right at file loading time, and unifies the xml and git
sample parsing to make them match. The new defaults are:
- unless anything else is explicitly specified, the primary sensor is
associated with the first tank, and the secondary sensor is
associated with the second tank
- if we're a CCR dive, and have an explicit oxygen tank, we associate
the secondary sensor with that oxygen cylinder. The primary sensor
will be switched over to the second cylinder if the oxygen cylinder
is the first one.
This may sound backwards, but matches our traditional behavior where
the O2 pressure was the secondary pressure.
This is definitely not pretty, but it gets our historical files working
right, and is at least reasonably sensible.

When we load sample data from a git save-file, we always default to
using the state from the previous sample (except for the special case of
cylinder pressure where an empty value does not mean "same", but
"interpolate", see core/load-git.c: new_sample()).
But the corollary to that is that it's always redundant to save sample
data that hasn't changed since the previous sample.
For some reason, the rbt, bearing and heartrate sample data didn't
follow that rule, and instead saved with lots of extra reduncancy.
(The alternative would be to clear those samples at load time, and make
them act like the pressure data, but it would appear that all these
three values may as well just have the normal "if no change, don't save
them" semantics).

This is a very timid start at making us actually use multiple sensors
without the magical special case for just CCR oxygen tracking.
It mainly does:
- turn the "sample->sensor" index into an array of two indexes, to
match the pressures themselves.
- get rid of dive->{oxygen_cylinder_index,diluent_cylinder_index},
since a CCR dive should now simply set the sample->sensor[] indices
correctly instead.
- in a couple of places, start actually looping over the sensors rather
than special-case the O2 case (although often the small "loops" are
just unrolled, since it's just two cases.
but in many cases we still end up only covering the zero sensor case,
because the CCR O2 sensor code coverage was fairly limited.
It's entirely possible (even likely) that this migth break some existing
case: it tries to be a fairly direct ("stupid") translation of the old
code, but unlike the preparatory patch this does actually does change
some semantics.
For example, right now the git loader code assumes that if the git save
data contains a o2pressure entry, it just hardcodes the O2 sensor index
to 1.
In fact, one issue is going to simply be that our file formats do not
have that multiple sensor format, but instead had very clearly encoded
things as being the CCR O2 pressure sensor.
But this is hopefully close to usable, and I will need feedback (and
maybe test cases) from people who have existing CCR dives with pressure
data.

We currently carry two pressures around for all the samples and plot
info, but the second pressure is reserved for CCR dives as the O2
cylinder pressure.
That's kind of annoying when we *could* use it for regular sidemount
dives as the secondary pressure.
So start prepping for that instead: don't make it "pressure" and
"o2pressure", make it just be an array of two pressure values.
NOTE! This is purely mindless prepwork. It literally just does a
search-and-replace, keeping the exact same semantics, so "pressure[1]"
is still just O2 pressure.
But at some future date, we can now start using it for a second sensor
value for sidemount instead.

The adapted define was confusingly wrong. Apparently, the BUFSIZ
define was coming from some include file, and was dependent on
platform (Linux 8K, Andorid 1K). Simple rewrite to a new define
and a proper value for both Linux and Android. If 4K is big
enhough, is a little uncertain, as its depends on the read
behavior of all libdivecomputer parsers using this serial
BLE interface.
The buffer size needed (on read, as that is the most prominent
direction when interfacing with DCs) is (most likely) 2x the
maximum block the libdc parsers request at once. I did not
study all parsers, but the Shearwater parser request 20 bytes
at once (we know that from the 1 packet at the time read, we
had before). The OSTC parser request 1K blocks for data
that is longer than 1K (like profiles, header tables).
The 1K we had on Android was working for Shearwater,
Eon Steel, but not for OSTC,as its reads 1K at the time
at max, and overflowing the buffer.
So 32k or 64k seems way to big (as in, much bigger than
any libdc read).

See also b409e9fc91 and 709c1df2af. The OSTC parser
cannot handle reads of single 20 byte BLE packages in serial mode.
Instead of doing a deeper down agressive read, we can read on
the serial level more subtile. As the parser is requesting a
specific number of bytes, we just read that number of bytes and
return them. As the 20 byte BLE packets do (obviously) not
align with the reading requirement of the libdc parser, a little
housekeeing needs to be done in between individual reads.

Commit 709c1df2af introduced a hard blocking read for BLE devices.
This did break BLE reads from multiple DCs, and (in hindsight) was not
a correct implementation. It would require, for example, dynamic
read buffers as especially profile data grows with dive time, and
in addition, and more importantly, also the OSTC libdc parser cannot
process the entire profile of a dive at once (but likes to receive
it in 1K blocks). So, basically, it introduced issues, and did not
solve the OSTC read.
This commit reverts this hard blocking read (and as such will break
OSTC BLE reads). But it enables removal of the special cases for
the EON Steel and G2.

only deals with credits granted by Subsurface to the OSTC to send

commands is NOT part of this commit, and is seemingly not needed

The current BLE read reads just one 20 bype packet. That packet size is set

is weird that those interfaces work with the current read() of just one
packet at the time.
As we need a blocking read (at least for the OSTC parser), just read all
data that is available on the input. And when we think we are done, give
the QtEventloop control to see if there is more, and process that incoming
data as well. All this basically implements a blocking read.

I hate changing the IO interfaces this often, but when I converted the
custom serial interface to the more generic custom IO interface, I
intentionally left the legacy serial operations alone, because I didn't
want to change something I didn't care about.
But it turns out that leaving them with the old calling convention
caused extra problems when converting the bluetooth serial code to have
the BLE GATT packet fall-back, which requires mixing two kinds of
operations.
Also, the packet_open() routine was passed a copy of the 'dc_context_t',
which makes it possible to update the 'dc_custom_io_t' field on the fly
at open time. That makes a lot of chaining operations much simpler,
since now you can chain the 'custom_io_t' at open time and then
libdivecomputer will automatically call the new routines instead of the
old ones.
That dc_context_t availability gets rid of all the
if (device && device->ops)
return device->ops->serial_xyz(..);
hackery inside the rfcomm routines - now we can just at open time do a simple
dc_context_set_custom_io(context, &ble_serial_ops);
to switch things over to the BLE version of the serial code instead.
Finally, SSRF_CUSTOM_IO v2 added an opaque "dc_user_device_t" pointer
argument to the custom_io descriptor, which gets filled in as the
custom_io is registered with the download context. Note that unlike
most opaque pointers, this one is opaque to *libdivecomputer*, and the
type is supposed to be supplied by the user.
We define the "dc_user_device_t" as our old "struct device_data_t",
making it "struct user_device_t" instead. That means that the IO
routines now get passed the device info showing what device they are
supposed to download for.
That, in turn, means that now our BLE GATT open code can take the device
type it opens for into account if it wants to. And it will want to,
since the rules for Shearwater are different from the rules for Suunto,
for example.
NOTE! Because of the interface change with libdivecomputer, this will
need a flag-day again where libdivecomputer and subsurface are updated

uuid. As soon the object created by toUtf8() gets destroyed, the uuid
pointer points to releases memory.

This is somewhat hacky, but it allows at least the Shearwater
libdivecomputer backend to continue to treat even the BLE GATT model as
just a serial protocol.
What it does is create a special "emulate serial behavior over the
packetized BLE protocol" helper layer, that qtserialbluetooth falls back
on when rfcomm is not available.
NOTE! This still requires some BLE packet code changes to work with the
odd way that Shearwater sets up their BLE GATT communication. So note
that no further patches are necessary to *libdivecomputer*, but some
updates are needed for the subsurface qt-ble.cpp code.
I have those updates in my tree, and this code is all tested on my
Perdix AI, but those patches are currently too ugly to commit as-is.
I've cleaned up this "fake serial" code sufficiently, that cleanup comes
next.

This seems a bit odd, but it actually has three different reasons for it:
- It's a visual indication of BT LE mode for users
- the rfcomm code only works with legacy BT support, and if we scan a
device that only does LE, we want the custom serial code to instead
automatically fall back on a "emulate serial over LE packets" model.
- we want rfcomm to remain the default for devices that do both legacy
BT _and_ LE, but we want people to have the ability to override the
choice manually. They can now do so by just editing the address
field and adding the "LE:" prefix manually, and it automatically gets
saved for next time.
So while a bit hacky, it's actually a very convenient model that not
only works automatically, but allows the manual override.

This is some very early and hacky code to be able to access BLE-enabled
dive computers that use the GATT protocol to send packets back and forth
(which seems to be pretty much all of them: a vendor-specific GATT
service with a write characteristic and a notification characteristic
for reading).
For testing only. But it does successfully let me download dives from
my EON Steel and my Scubapro G2.
NOTE! There are several very hacky pieces in here, including just
"knowing" that the write characteristic is the first one, and the
notification characteristic is second. The code should actually check
the properties rather than have those kinds of hardcoded assumptions.
It also checks "vendor specific" by looking at the UUID string
representation, and knowing that the standard ones start with zero.
Crazily, there doesn't seem to be any normal way to test for this,
although I guess that maybe the uuid.minimumSize() function could be
used.
There are other nasty corners. Don't complain, send me patches.

Instead of being "custom serial", it's a IO model that allows serial or
packet modes, independently of each other (ie you can have a bluetooth
device that does serial over BT rfcomm and packet-based communication
over BLE GATT with the same serial operations that describe both cases).

This way in the en_US locale we no longer get shown the odd "dive(s)"
and instead get correct singular and plural forms.
Most of the patch is just a reindentation as it removes the if clause
that used to do the special case of NOT loading a translation for the
en_US case.
Right now we start with a trivial en_US translation file. My guess is
that this will be overwritten once we do the next round of "new strings,
new translations".

This changeset fixes 5 issues specific to importing from Liquivision dive logs:
Issue #1: Buffer overrun causes segmentation fault.
At the end of a dive record, untranslatable data is skipped and the file is
scanned for the start of the next dive. This scan was implemented without
regard to buffer size and so the scan ran over the buffer boundary when trying
to scan for the next record after importing the last record in the file.
Issue #2: Incorrect identification of the primary sensor.
The primary tank pressure transmitter was being identified by using the sensor
ID reported in the first pressure event record encountered. When diving with
multiple transmitters (buddy, student, or group transmitters), this is often
not the case and results in the buddy or other group transmitter's pressure
data being imported instead of the primary's.
Through empirical observation of several multi-sensor logs, I identified a
previously unhandled event code (0x10) as marking a sensor identification
event record. Parsing this record allows the primary and other sensors
to be definitively identified regardless of which one sends the first pressure
event.
Issue #3: Sensor values added to the sample collection regardless of sensor ID.
When processing events, the code previously dropped through to create a sample
for every pressure event record, regardless of which sensor ID that event is
associated with. Pressure events for sensors other than the primary are now
ignored and omitted from the sample collection.
Issue #4: Duplicate samples when pressure event time syncs with sample time.
The sample index (d) was not incremented in this specific case resulting in
a duplicate sample (for the same sample time) being created when processing
the next pressure event record.
Issue #5: Unsigned time difference results in erroneous interpolated samples.
When interpolating/extrapolating depth and temperature values for a between-
samples pressure event, a signed time value is subtracted from an unsigned time
value, resulting in an unsigned term. This term is used as a scaling factor
and should be signed to allow for a negative value. Currently, negative values
are instead treated as large unsigned values which result in erroneous scaled
depth and temperature values.

Major functional change in this commit is the addition of found static BT devices
to the internal administration (on Android), in a way that is equivalent to
mobile-on-desktop. So, in both cases, the list of devices in the app are
as in the list of devices on the host OS (Linux or Android). To minimize code
duplication, the btDeviceDiscovered slot is split in two parts, the part to
act as slot for the Qt BT discovery agent (Linux, so mobile-on-desktop), and
the part only needed for Android.
Remaining to be fixed: the correct handling of the QML UI selection of
vendor/product. The first default dive computer is correctly detected,
all paired devices from the virtual vendow can be selected, but clicking
through vendors results in non logical selections. It is obvious why
this is, but a fix is not straigforward at this point.

This seems a very trivial commit, but it is not. It appears that on an Android
build, with defined(Q_OS_ANDROID) the Q_OS_LINUX variable is also defined.
This results in a very tricky discovery process: 1) the JNI stuff pulls the paired
devices from the local BT controller, and 2) The QT discovry agent gets active
BT devices. 1) is a static list, that is, not dependent on actual
visual/discoverable BT devices; it is just cached data from the phone. 2) On
Android, this results in a list of actively visible (paired and not paired)
devices. On desktop, however (with QT/bluez BT stack) the QT discovery agent
just gets the list of paired devices, so more or less equivalent to the situation
described under 1) for Android.
Ok, a long story, but just do not do a discovery on Android at all. Basically,
we need the BT address, device name, and possibly a specific SPP service UUID. This are
fixed and known for HW and Shearwater at this point, so there is no need for a
(lengthy) discovery process, and making sure the the dive computer is discoverable
at the moment the app wants to construct its data to show in the UI. So, the
static list of paired devices is all we need.
