Now that gas switch events always have indices into the cylinder table,
start using that to look up the gas mix from the cylinders rather than
from the gas switch event itself. In other words, the cylinder index is
now the primary data for gas switch events.
This means that now as you change the cylinder information, the gas
switch events will automatically update to reflect those changes.
Note that on loading data from the outside (either from a xml file, from
a git/cloud account, or from a dive computer), we may or may not
initially have an index for the gas change event. The external data may
be from an older version of subsurface, or it may be from a
libdivecomputer download that just doesn't give index data at all.
In that case, we will do:
- if there is no index, but there is explicit gas mix information, we
will look up the index based on that gas mix, picking the cylinder
that has the closest mix.
- if there isn't even explicit gas mix data, so we only have the event
value from libdivecomputer, we will turn that value into a gasmix,
and use that to look up the cylinder index as above.
- if no valid cylinder information is available at all, gas switch
events will just be dropped.
When saving the data, we now always save the cylinder index, and the gas
mix associated with that cylinder (that gas mix will be ignored on load,
since the index is the primary, but it makes the event much easier to
read).
It is worth noting we do not modify the libdivecomputer value, even if
the gasmix has changed, so that remains as a record of the original
download.

In commit df4e26c875 ("Start sanitizing gaschange event information")
back about a year and a half ago, I started sanitizing the gas switch
event data, allowing gas switches to be associated with a particular
cylinder index rather than just the gas mix that is switched to.
But that initial step only _allowed_ a gas switch event to be associated
with a particular cylinder, the primary model was still to just specify
the mix.
This finally takes the next step, and *always* associates a gas switch
event with a particular cylinder. Instead of then looking up the
cylinder by trying to match gas mixes at runtime, subsurface now looks
it up when loading the dive initially as part of the dive fixup code.
The switch event still has an a separate gas mix associated with it, but
this patch also starts preparing for entirely relying on the gas mix in
the cylinder itself, by starting to pass in not just the event but also
the dive pointer to the routines that look up gas mix details.

The gas switch event handling is somewhat fragile, mostly because the
legacy event encoding for gas switches is odd. It's also limited to
whole percentages, unlike our internal gas mix model.
In addition, it also ends up comparing the values to the raw permille
values, which is wrong for air, and wouldn't match our O2_IN_AIR which
is 209 permille (closest approximation to 20.946%).
So handle air separately, since "21" really is a valid oxygen value for
air, and should match 20.9%. And use the proper accessor functions to
get the gasmix values.

Dirk says that divinglog hasn't been doing the linear pressure
interpolation for a long while, so we're doing extra dive fixups that
really aren't needed any more.
Also, the code is actually buggy: it only ever worked on the first
cylinder anyway (because only the first cylinder pressure_delta[] would
be initialized). That was probably perfectly fine in practice, since
it's unlikely that many tech divers used old versions of divinglog
anyway, so the bug per se isn't a reason to remove it - but it is a sign
that the code was a bit hard to read, so let's get rid of it if there is
no reason to maintain it or fix it.

Having subsurface-core as a directory name really messes with
autocomplete and is obviously redundant. Simmilarly, qt-mobile caused an
autocomplete conflict and also was inconsistent with the desktop-widget
name for the directory containing the "other" UI.
And while cleaning up the resulting change in the path name for include
files, I decided to clean up those even more to make them consistent
overall.
This could have been handled in more commits, but since this requires a
make clean before the build, it seemed more sensible to do it all in one.

This caches the git ID for the dive on load, and avoids building the
dive directory and hashing it on save as long as nothing has invalidated
the git ID cache.
That should make it much faster to write back data to the git
repository, since the dive tree structure and the divecomputer blobs in
particular are the bulk of it (due to all the sample data). It's not
actually the git operations that are all that expensive, it's literally
generating the big blob with all the snprintf() calls for the data.
The git save used to be a fairly expensive with large data sets,
especially noticeable on mobile with much weaker CPU's. This should
speed things up by at least a factor of two.

This is useful if you are in an area with slow or spotty network and if
you are fine with just saving to the phone. In order to sync to the cloud
you either have to manually sync via the menu or turn this back on and
hide the application.
The commit also removes the old refresh from the Manage dives menu as the
semantic of that was possibly destructive now that we no longer
immediately save changes to git - those could be thrown away by selecting
refresh before the app had a chance to save them.

There may be other paths where we potentially show the wrong status to
the user... but at least with this it times out eventually; there
shouldn't be any single operation that isn't broken down with progress
markers that takes more than 10 seconds, so keeping the notification
around for 30 seconds seems very conservative.

Much as this felt like the prudent thing to do, it makes the UI painful
to use. In bad network conditions, with a large dive log, on a phone,
the save operation can take more than a minute - which is just completely
ludicrous.
So instead we mark the dive list changed when we make changes and wait
for the app to not be in the foreground. Once the OS tells us that we are
hidden (on the desktop that generally means we don't have focus, on a
mobile device it usually does mean that the app is not on the screen), we
check if there are data to be saved and do so.
There is of course a major problem with this logic. If the user switches
away from Subsurface-mobile but comes back fairly quickly (just reacting
to a notification or briefly checking something, changing a song,
something... then the app may still be non-responsive for quite a while.
So we need to do something about the time it takes us to save the git
tree locally, and then figure out if we can move at least some of the
network traffic to another thread.
And we need to make sure the user immediately notices that the app is not
crashed but is actually saving their data. But that's for another commit.
tl;dr: CAREFUL, don't kill Subsurface-mobile before it had time to save
your data or your changes may be gone. In typical use that shouldn't be
an issue, but it is something that we need to tell the user about.

This allows fairly fine grained analysis on what part of loading from
and saving to git we are spending our time. Compute performance and
network speed play a significant role in how all this plays out.
The routine to check if we can reach the cloud server is modified to
send updates every second so we don't hang without any feedback for five
seconds when there is network but we can't reach the cloud server (not
an unlikely scenario in many dive locations with poor network quality)

If you show the App log and then start "Add dive manually" or "Show GPS
fixes" you get this odd behavior that the page stack returns to the App
log for some reason. A simple workaround is of course to return to the
dive list, first. Not ideal (because there shouldn't be a reason not to
have the All log in the stack as well, but not really a big problem,
either, since the App log is mainly intended for developers.

This bug admittedly hits almost nobody, but if you had multiple cylinder
pressure sensors on the same cylinder (attached to multiple dive
computers, of course), we would take the beginning pressure from the
first dive computer, and the ending pressure from the last dive
computer.
That came about because we'd just walk all the dive computer samples in
order, and the first time we see a relevant sample and we don't have a
beginning pressure, we'd take that pressure. So the beginning pressure
was from the first dive computer, and once we'd seen a valid beginning
pressure, that would never change.
But as we're walking along, we'd continue to update the ending pressure
from the last relevant sample we see, which means that as we go on to
look at the other dive computers, we'd continue to update the ending
pressure with data from them.
And mixing beginning/ending pressures from two different sensors just
does not make sense.
This changes the logic to be the same for beginning and ending
pressures: we only update it once, with the first relevant sample we
see. But we walk the samples twice: forwards from the beginning to
find the first beginning pressure, and backwards from the end to find
the ending pressure.
That means that as we move on to the second dive computer, we've now
filled in the ending pressure from the first one, and will no longer
update it any more.
NOTE! We don't stop scanning the samples (or the dive computers) just
because we've found a valid pressure value. We'll always walk all the
samples because there might be multiple different cylinders that get
pressure data from different samples (and different dive computers).
We could have some early-out logic when we've filled in all relevant
cylinders, but since this just runs once per dive it's not worth it.

fixup_dive_dc() is called for each dive computer when we add a new dive.
It does various housekeeping functions, cleaning up the sample data, and
fixing up dive details as a result of the sample data.
The function has grown to be a monster over time, and particularly the
central "walk every sample" loop has become an unreadable mess.
And the thing is, this isn't even all that performance-critical: it's
only done once per dive and dc, and there is no reason to have a single
illegible and complex loop.
So split up that loop into several smaller pieces that each will loop
individually over the sample data, and do just one thing. So now we
have separate functions for
- fixing up the depth samples with interpolation
- fixing up dive temperature data
- correcting the cylinder pressure sensor index
- cleaning up the actual sample pressures
Yes, this way we walk the samples multiple times, but the end result is
that the code is much easier to understand. There should be no actual
behavioral differences from this cleanup, except for the fact that since
the code is much more understandable, this cleanup also fixed a bug:
In the temperature fixup, we would fix up the overall dive temperatures
based on the dive computer temperatures. But we would then fix up the
overall dive computer temperature based on the sample temperature
*afterwards*, which wouldn't then be reflected in the overall dive
temperatures.
There was another non-symptomatic bug that became obvious when doing
this cleanup: the code used to calculate a 'depthtime' over the dive
that was never actually used. That's a historical artifact of old code
that had become dead when the average depth calculations were moved to a
function of their own earlier.
This is preparatory for fixing the overall cylinder pressure stats,
which are currently wrong for dives with multiple dive computers: we
currently take the starting cylinder pressure from the *first* dive
computer that has cylinder pressure information, but we take the ending
cylinder pressure from the *last* dive computer with cylinder pressure
information.
This does not fix that bug, but without this cleanup fixing that would
be a nightmare due to the previous complicated "do everything in one
single loop" model.
