If there are no gas mixes returned by libdivecomputer, we need to default to air. The previous commit would have defaulted to pure oxygen.

During code review, an argument was made to use the bottom gas mix as
the mix to fill additional tanks with instead of the last mix reported
by the dive computer.
This change implements `get_deeper_gasmix` which compares two gas mixes
and returns the one with the lower MOD. This comparison does not perform
actual MOD calculations but only performs a relative oxygen and helium
content comparison.
Instead of saving the last gas mix and assigning it to additional tanks,
a `bottom_gas` mix is saved and assigned instead.

Reverted "optimisation" based on code feedback.
Firstly, it's implementation-defined whether or not a stack frame is created for sub-scopes, secondly any optimisation is questionable regardless, and thirdly it was felt that it makes the code harder to understand.

Instead of defaulting to air when we run out of gas mixes to assign to
cylinders, use the last gas mix provided by the dive computer.
If no gas mixes are provided at all, then default to air.
This prevents Subsurface from "inventing" gas mixes which are not
reported by the dive computer. It also works very nicely with a sidemount
configuration where the dive computer typically reports two cylinders but
only a single gas mix.

The divecomputer_device_open() function tries all supported transports
one by one, and exits as soon as one is opened successfully. When the
end of the function is reached, the DC_STATUS_UNSUPPORTED error code is
returned.
The annoying side effect is that the actual error code returned by the
transport is ignored and changed into DC_STATUS_UNSUPPORTED. This is
very confusing while troubleshooting download problems.
Fixed by initializing the error code to DC_STATUS_UNSUPPORTED, in case
no transport is available for trying, and returning the last reported
error to caller.

The existing logic correctly calculates the minimum (ie, ending) pressure, but not the maximum
(ie starting) pressure.
For example, 2 tanks A and B with manual pressures (same tank on subsequent dives, which were
then merged):
A: 205 - 84
B: 83 - 55
When merging the starting pressures, the call is : merge_pressure(205, 0, 83, 0, false)
The final comparison is:
if(false && 205 < 83) return 205;
else return 83;
-> So 83 is returned even though 205 should have been.

Fix how gases are marked as 'used' and kept from being deleted in the
equipment tab for CCR dives.
It does not make sense to treat the (arbitrary) first gas in the list
with a usage type of 'diluent' or 'oxygen' as 'used' and prevent the
user from deleting it. Dive computers report the initial diluent and
any other diluents used through a 'gaschange' event, so the actually
used diluents are already picked up as part of gaschange event based
logic.
Also clarify the selection of the first diluent used as a default if no
gaschange events exist.
Also fixed the test data - gases that have a pressure change should be
included in the profile if they do not have a gas change recorded
against them by other dive computers, even if they are oxygen.
A secondary problem shown by this is that the pressure change is not
applied to the profile - the pressure is currently shown as constant on
the start pressure. But this is for another pull request.

Include unused tanks in merges of multiple logs into a single dive if
the 'Show unused cylinders' preference is enabled.
Also rename the preference (in code) to `include_unused_tanks` to
reflect the fact that it is already used in more places than just the
display (exporting, cloning dives).
Simplified the cylinder model to make forced inclusion of unused tanks
dependent on use of the model in planner.
Leaving the persisted name of the preference as `display_unused_tanks`
to avoid resetting this for all users - is there a good way to migrate
preference names?

The memory management and string concatenation was hard to follow.
Since the mobile files ios.cpp and android.cpp were already
converted to C++, let's do the same for Unix, Windows and MacOS.
Simply store the default directory and filename in a function-level
static string. Thus, it will be initialized on first call and
freed on application exit. Since the std::string data is
guaranteed to be contiguous and zero-terminated, it can be used
from C code.

Add support for tracking the gas usage across multiple tanks to the 'bar
used' and SAC values shown for the profile ruler.
The following rules are implemented:
- a tank is considered 'used' if at least one bar has been consumed;
- only used tanks are taken into account for calculations;
- 'bar used' is only shown if all tanks used have the same (or unknown)
volume;
- SAC is only shown if all tanks used have a known volume.
Fixes#3902.

The trip selection code was an awkward layering violation.
Whereas dive selections due to dive undo-commands trickled
down via DiveTripModel-->MultiFilterSortModel-->DiveListView,
for trip editing, the DiveListView directly intercepted the
TripEdited signal.
Instead, mimic the dive-selection code. This is a bit longer
but more consistent and logical. The undo/redo of trip changes
is now also a "programmatical" change of the selection.

delete_single_dive() is one of those remnants from before the
undo-code. Now it is only called in two contexts:
1) When clearing the whole dive log.
2) When importing dives from the cloud on mobile.
In the first case, the selection is cleared before deleting
the dives.
In the second case, let's just do the same.
Thus, we can remove the last call to the deselect_dive()
function that does some complex calculations concerning
the current dive and divecomputer.

Each of these calls recalculates the current dive and divecomputer.
Instead, collect the dives to be selected/deselected and (de)select
them at once.
This needs some code refactoring in the core, because we need a
function that
1) doesn't send a signal by itself.
2) doesn't clear the trip-selection.
This contains some reorganization of the selection functions
signatures: The filter code is the only caller that keeps the
selected dive and the only caller that cares about whether the
current dive changed. So let only the function that keeps the
selected dive return whether the current dive changed.
It's all very fragile.

For each selected dive that is hidden by the filter,

only once.

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.
