This tries to encapsulate the management of the current dive and
divecomputer in the selection code. The current dive is alreay
set by setSelection(). Add a new parameter to also set the
current divecomputer. If -1 is passed, then the current
computer number is remained. This will allow us to audit the code.
Because for now, the whole "current dive computer" thing seems
to be ill-defined.
This fixes a bug: the dive-computer number wasn't validated
when making a new dive the current dive. The new code has some
drawbacks though: when selecting a whole trip, the validation
will be called for all dives in the trip and thus the dive computer
number will depend on the dive with the lowest amount of dive
computers in the trip. This will need to be fixed.

The parser API was very annoying, as a number of tables
to-be-filled were passed in as pointers. The goal of this
commit is to collect all these tables in a single struct.
This should make it (more or less) clear what is actually
written into the divelog files.
Moreover, it should now be rather easy to search for
instances, where the global logfile is accessed (and it
turns out that there are many!).
The divelog struct does not contain the tables as substructs,
but only collects pointers. The idea is that the "divelog.h"
file can be included without all the other files describing
the numerous tables.
To make it easier to use from C++ parts of the code, the
struct implements a constructor and a destructor. Sadly,
we can't use smart pointers, since the pointers are accessed
from C code. Therfore the constructor and destructor are
quite complex.
The whole commit is large, but was mostly an automatic
conversion.
One oddity of note: the divelog structure also contains
the "autogroup" flag, since that is saved in the divelog.
This actually fixes a bug: Before, when importing dives
from a different log, the autogroup flag was overwritten.
This was probably not intended and does not happen anymore.

Instead of adding all gases read from a dive computer as part of a dive

the current gas ad depth.
A follow up question from this is whether gas use in the cylinders list
on the Equipment tab should be user editable. This seems to be
inconsistent at the moment, with gas constituent percentages downloaded
from the dive computer being editable, but gas use not.

fixup_dc_sample_sensors() would make sure that any pressure sensor
indexes were in range of the cylinders by just clearing the pressure
data if the sensor index was larger than the number of cylinders in the
dive.
That certainly makes the sensor index data consistent, but at the cost
of just dropping the sensor data entirely.
Dirk had some cases of odd sensor data (probably because of an older
version of subsurface, but possibly due to removing cylinders manually
or because of oddities with the downloader for the Atomic Aquatics
Cobalt dive computer he used), and when re-saving the dive, the pressure
data would magically just get removed due to this.
So rewrite the sensor data fixup to strive very hard to avoid throwing
pressure sensor data away. The simplest way to do that is to just add
the required number of cylinders, and then people can fix up their dives
manually by remapping the sensor data.
This whole "we clear the pressure data" was at least partly hidden by
two things:
(1) in the git save format, we don't rewrite dives unless you've
changed the dive some way, so old dives stay around with old data
in the save until explicitly changed.
(2) if you had multiple dive computers, and one dive computer does not
have any pressure data but another one does, our profile will use
that "other" dive computer pressure data (because often times you
might have only one dive computer that is air integrated, but you
still want to see the tank pressure when you look at other dive
computers - or you have one dive computer give pressure data for
your deco bottle, and another for your travel gas etc).
So those two facts hid the reality that we had actually cleared the tank
sensor data for Dirk's dive with the Atomic Aquatics dive computer,
because we'd still see pressure data in the profile, and the git data
would still be the old one.
Until Dirk renumbered his dives, and the data was rewritten.

The git save format is designed to be entirely line-based, where all the
dive data is on individual lines that are independent.
That is very much by design, so that you can merge these files
automatically, and not worry about what it does to the context (contrast
this to structured files like JSON or XML, where you have multiple
levels of indentation, and the context of a line matters).
So the parser can just ignore any conflict markers, and parse everything
one line at a time.
Well, almost.
We do have *one* special form of multi-line context, where flowed text
(think things like dive notes) will have one "header line" that starts
the note, and then it can continue for several lines until the final
line that ends the quote.
In such a situation, the dive merging can result in a partially merged
string note, which has the ending line from one dive, and then continues
with more string data from the other dive.
That will confuse our parser mightily, because it will have seen the end
of the string, and parsed the rest of those string comments as garbage lines.
That part in itself is fine - the garbage lines won't pass as any real
data (because they don't start with a proper keyword), but while parsing
that garbage the *next* end of the string will be seen as a start of a
new string.
And *that* then confuses the git parser to think that the line after
that is now part of the string, and so it won't correctly parse the
non-string line that follows.
To give a more concrete example, the git dive data (here indented and
abbreviated) might look like this:
suit "5mm long + 3mm hooded vest"
notes "First boat dive.
Giant-stride entry."
Saw a turtle."
cylinder vol=10.0l description="10.0ℓ" depth=66.019m
where the two notes from the two dives were
notes "First boat dive.
Giant-stride entry"
and
notes "First boat dive.
Saw a turtle."
respectively, and the merged result contained parts of both.
When we parse this, we will parse the 'notes' line as having the string
First boat dive.
Giant-stride entry
which is fine. But then the next line will be that
Saw a turtle."
and now the ending double quote character on that line will be seen as
the beginning of a new string, and the cylinder information on the next
line will then be mixed up. The resulting mess will be ignored, but in
the process the data on the "cylinder" line will basically have been
lost.
There are several ways to deal with this, but this particular fix
depends on the fact that we can recognize stale string continuation
lines: they are either empty (for an empty line), or they start with a
TAB character.
So to solve the problem with the mis-identified end quote, this
recognizes that we're in such a "stale left-over comment line" context,
and will just skip such lines entirely.
That does mean that when you have conflicts in dive note sections due to
having edited the dive concurrently on different machines, you may just
lose some of the edits.
But this way at least you shouldn't lose any other data due to the merge
conflict.
NOTE! We could try to improve on this by instead noticing that a "end of
multi-line string has a continuation entry on the next line", and just
say "ok, that wasn't a real end after all".
But that would be an independent thing anyway - this "ignore stale text
comment lines" logic would be required anyway, in case those stale text
comments ended up somewhere *else* than right after another text line.
So do this more important fix first.

input before parsing the second coordinate. Prior to this patch, if the
coordinate format was in degrees followed by a sign (N is a sign in this
example), the parser would skip the bit of code that fast forwards past
any intervening separators and whitespace (, in this example). This
resulted in coordinates of this form not being accepted, because the
second parse would start with , 68.2296° W and reject this as an invalid
coordinate.
To rectify this, the bit of code that fast forwards past separators and
whitespace has been broken out from the tokenization loop and performed
as a final step after a single coordinate has been completely parsed and
validated. Doing it this way makes it independent of the state of the
tokenizer, so that the fast-forward code will always execute once a
coordinate has been successfully parsed.
I've also centralized the list of allowed separators into its own static
string; this is necessary as part of the patch but should also make
allowing additional separator characters between coordinates trivial in
the future, if needed.

Many language have country specific differences. We recognize different
flavors of English (US, UK (and South Africa)), German (Germany and
Switzerland), and Portuguese (Brazil and Portugal). For many other
flavors of the languages that we have translations for we have no
support and the way we hard-coded the fallbacks in the past was odd and
meant that in the cases where we do have two flavors, missing strings in
one weren't taken from the other (English as the default language being
the exception).
This tries to do a better job of recognizing some of those parent
languages and loading translators for them, first. Which means if we
then find a translator for the specific language (i.e., de_CH), strings
missing in that translation are next searched in the parent language
(de_DE), before finally providing the source language string (en_US).

The fact that Qt6 changes the arguments to all these functions from
double to float is... hard to explain, but it is what it is. With these
changes, for the majority of cases we create inlined helpers that
conditionally compile to do the right thing. And in a handful of other
cases we simply cast to float (and accept that on Qt5 this then gets
cast back to double... for none of these cases the potential loss in
precision makes any difference, anyway - which likely is why the Qt

This tries to make our fingerprinting code work better, by avoiding
using the "deviceid" field that has always been unreliable because we've
calculated it multiple different ways, and even for the same version of
subsurface, it ends up changing in the middle (ie we calculate one value
initially, then re-calculate it when we have a proper serial number
string).
So instead, the fingerprinting code will look up and save the
fingerprint file using purely "stable" information that is available
early during the download:
- the device model name (which is a string with vendor and product name
separated by a space)
- the DC_EVENT_DEVINFO 32-bit 'serial' number (which is not necessarily
a real serial number at all, but hopefully at least a unique number
for the particular product)
but because the model name is not necessarily a good filename (think
slashes and other possibly invalid characters), we hash that model name
and use the resulting hex number in the fingerprint file name.
This way the fingerprint file is unambiguous at load and save time, and
depends purely on libdivecomputer data.
But because we also need to verify that we have the actual _dive_
associated with that fingerprint, we also need to save the final
deviceid and diveid when saving the fingerprint file, so that when we
load it again we can look up the dive and verify that we have it before
we use the fingerprint data.
To do that, the fingerprint file itself contains not just the
fingerprint data from libdivecomputer, but the last 8 bytes of the file
are the (subsurface) deviceid and the diveid of the dive that is
associated with the fingerprint.

When we save the divecomputer data, we never actually save the serial
value as a field. We used to rely on saving the very dodgy 'deviceid',
and then look up the serial number from there. And that never really
worked reliably, but we didn't really notice, because we never really
_used_ the serial number anywhere.
The only place the serial number is actually reliably displayed is in
the "Extra data" tab, which contains the key value pairs, and that's
where the original dive download code got the serial number from.
So just parse that at load time too, the same way we parsed it at dive
download time.
In fact, do the firmware version the same way, and remove the code from
the downloader, since it too can rely on 'add_extra_data()' just picking
up the information directly.

We have this odd legacy notion of a divecomputer 'device', that was
originally just basically the libdivecomputer 'EVENT_DEVINFO' report
that was associated with each dive. So it had firmware version,
deviceid, and serial number.
It had also gotten extended to do 'nickname' handling, and it was all
confusing, ugly and bad. It was particularly bad because it wasn't
actually a 'per device' thing at all: due to the firmware field, a dive
computer that got a firmware update forced a new 'device'.
To make matters worse, the 'deviceid' was also almost random, because
we've calculated it a couple of different ways, and libdivecomputer
itself has changed how the legacy 32-bit 'serial number' is expressed.
Finally, because of all these issues, we didn't even try to make the
thing unique, so it really ended up being a random snapshot of the state
of the dive computer at the time of a dive, and sometimes we'd pick one,
and sometimes another, since they weren't really well-defined.
So get rid of all this confusion.
The new rules:
- the actual random dive computer state at the time of a dive is kept
in the dive data. So if you want to know the firmware version, it
should be in the 'extra data'
- the only serial number that matters is the string one in the extra
data, because that's the one that actually matches what the dive
computer reports, and isn't some random 32-bit integer with ambiguous
formatting.
- the 'device id' - the thing we match with (together with the model
name, eg "Suunto EON Steel") is purely a hash of the real serial
number.
The device ID that libdivecomputer reports in EVENT_DEVINFO is
ignored, as is the device ID we've saved in the XML or git files. If
we have a serial number, the device ID will be uniquely associated
with that serial number, and if we don't have one, the device ID will
be zero (for 'match anything').
So now 'deviceid' is literally just a shorthand for the serial number
string, and the two are joined at the hip.
- the 'device' managament is _only_ used to track devices that have
serial numbers _and_ nicknames. So no more different device
structures just because one had a nickname and the other didn't etc.
Without a serial number, the device is 'anonymous' and fundamentally
cannot be distinguished from other devices of the same model, so a
nickname is meaningless. And without a nickname, there is no point in
creating a device data structure, since all the data is in the dive
itself and the device structure wouldn't add any value..
These rules mean that we no longer have ambiguous 'device' structures,
and we can never have duplicates that can confuse us.
This does mean that you can't give a nickname to a device that cannot be
uniquely identified with a serial number, but those are happily fairly
rare (and mostly older ones). Dirk said he'd look at what it takes to
give more dive computers proper serial numbers, and I already did it for
the Garmin Descent family yesterday.
(Honesty in advertizing: right now you can't add a nickname to a dive
computer that doesn't already have one, because such a dive computer
will not have a device structure. But that's a UI issue, and I'll sort
that out separately)

Before making the cylinder-table dynamic, dives always
had at least one cylinger. When such a dive is displayed,
the TabDiveInformation class calls per_cylinder_mean_depth().
If there are no samples, this function generates a "fake
profile" with fake_dc(). Thus, effectively dives always
had samples once the user was displaying them.
When the cylinder-table was made dynamic, dives without
cylinders were supported. This can notably happen, when
importing from CSV (this could actually be a bug).
per_cylinder_mean_depth() exits early in that case and
doesn't create a fake profile. This lead to crashes
of the profile-widget, which were fixed in 6b2e56e513.
Non-sample dives were now shown with the Subsurface-logo.
To restore the previous behavior, genarate a fake profile
for sample-less dives in fixup_dive(), which is called
anytime a dive is loaded or imported. This seems to
have been the intention anyway and this worked only
"by chance". This will make a few fake_dc() calls obsolete,

When merging two dives, the higher CNS value was taken. This could
result in inconsistent CNS values if two dives were merged where
one dive's CNS was calculated from a "fake profile", i.e. a dive
without dive-computer profile. In that case, the most conservative
value (all time spent at the bottom) was assumed. The merged dive
then consisted of the dive-computer profile and the conservative
CNS estimate.
This is fixed by setting the CNS value to "0" after merging,
which means "unknown". The correct value will then be recalculated
in "fixup_dive" from the actual sample data.

The data of the membuffer is passed as a data/length pair
to xmlReadMemory(). There is no point in NUL-terminating it.
Moreover, pass the data directly to xmlReadMemory()
instead of via variables. These variables are reused
later with a different meaning, making this super-confusing.
The membuf variable is turned from "const char *" to "char *"
to signal that we own the buffer.
Amazingly, zip_source_buffer() frees the buffer, even though
a "const void *" is passed in. This API is pure madness. Add

C-style memory management is a pain and nearly nobody seems to get

when it gets out-of-scope. Originally, I was thinking about
conditionally adding a constructor/destructor pair when compiling

because it would be extremely confusing to have behavioral change
when changing a source from from C to C++ or vice-versa.

By default, the parser would create samples with cylinder

The backend infrastructure will soon be able to support more than one
cloud server which automagically stay in sync with each other.
One critical requirement for that to work is that once a session was
started with one of the servers, the complete session happens with that
server - we must not switch from server to server while doing a git
transaction. To make sure that's the case, we aren't trying to use DNS
tricks to make this load balancing scheme work, but instead try to
determine at program start which server is the best one to use.
Right now this is super simplistic. Two servers, one in the US, one in
Europe. By default we use the European server (most of our users appear
to be in Europe), but if we can figure out that the client is actually
in the Americas, use the US server. We might improve that heuristic over
time, but as a first attempt it seems not entirely bogus.
The way this is implemented is a simple combination of two free
webservices that together appear to give us a very reliable estimate
which continent the user is located on.
api.ipify.org gives us our external IP address
ip-api.com gives us the continent that IP address is on
If any of this fails or takes too long to respond, we simply ignore it
since either server will work. One oddity is that if we decide to change
servers we only change the settings that are stored on disk, not the
runtime preferences. This goes back to the comment above that we have to
avoid changing servers in mid sync.

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.

Since the view of the quadrants is not determined by the
