Determining the correct cylinder index from a known gas mix can be
complicated, but it is trivial to look up the gasmix from the cylinder_t
structure.
It makes sense to remember which cylinder is being used. This simplifies
handling changing a cylinder's gas mix, either directly by the user, or
indirectly in the planner. It also permits tracking of multiple cylinders of
the same mix, e.g. independent twins / sidemount.

We have two different models for setting the deviceid associated with a
dive computer: either take the value from the libdivecomputer 'devinfo'
field (from the DC_EVENT_DEVINFO event), or generate the device ID by
just hashing the serial number string.
The one thing we do *not* want to have, is to use both methods, so that
the same device generates different device IDs. Because then we'll
think we have two different dive computers even though they are one and
the same.
Usually, this is not an issue, because libdivecomputer either sends the
DEVINFO event or gives us the serial number string, and we'll always
just pick one or the other.
However, in the case of at least the Suunto EON Steel, I intentionally
did *not* send the DC_EVENT_DEVINFO event, because it gives no useful
information. We used the serial number string to generate a device ID,
and everything was fine.
However, in commit d40cdb4755ee ("Add the devinfo event") in the
libdivecomputer tree, Jeff started generating those DC_EVENT_DEVINFO
events for the EON Steel too, and suddenly subsurface would start using
a device ID based on that instead.
The situation is inherently ambiguous - for the EON Steel, we want to
use the hash of the serial number (because that is what we've
historically done), but other dive computers might want to use the
DEVINFO data (because that is what _those_ backends have historically
done, even if they might also implement the new serial string model).
This commit makes subsurface resolve this ambiguity by simply preferring
whatever previous device ID it has associated with that particular
serial number string. If you have no previous device IDs, it doesn't
matter which one you pick.

We could create a plot_info data that didn't contain all the time slots
for the events fromt he dive computer, which would terminally confuse
the plotting of the event profile widgets because it couldn't match up
the event with the dive plot data model.
So for example, in DiveEventItem::recalculatePos(), when the code tries
to figure out the spot in the data model, it could fail, and then try to
hide the event (because without the data model information it doesn't
know where it should go). But that hiding would then not match the
logic in DiveEventItem::shouldBeHidden(), and the event would end up
being shown in the upper left-hand corner of the profile after all.
The reason the plot_info data wouldn't contain the time slots is that
the slots are allocated primarily for the sample data, and then the
events would be added in between sample data in populate_plot_entries().
But since we'd only add the event pointer *between* samples, that would
mean that events after the last samples would not get plot-info points
allocated to them.
That issue was exacerbated by how we also truncate uninteresting samples
at the end when some dive computers end up giving a long stream
(possibly several minutes) of "at the surface" events before they
finally turn off logging.
This makes sure that we take the event timestamps into account for the
"maxtime" calculation, and also that we finish populating the plot_info
data with any final event timestamps.
Now all the events will have a matching plot_info entry.

There are cases where we actually want to keep them, as exemplified by
this situation from Richard Yorke:
"I have just come across a situation when ignoring the surface marker
is a disadvantage. I have just had a problem with my BC feed
seeping, slowly filling my BC and as I control my buoyancy on the
bottom using the air in my drysuit, I did not notice, so that when I
came to ascend the expanding air in my BC caused a loss of control.
Fortunately not from a great depth and no untoward consequences.
However, the Subsurface profile only shows me rising to 4m and
descending to 5.5m for my safety stop. However I actually broke the
surface and descented to 5.5 but the frequency of recording depth was
not fast enough to show this as it was so brief"
so remove the code that ignores the surface events entirely.
I think we'll have to come up with some smarter filtering model for
showing them, but that is predicated on getting these events to come
through in the first place.

I couldn't figure out how to break this down into small, useful commits.
Part of the problem is that I kept going while working on this and as you
can see from looking at the commit, diff tries so hard to find small code
fragments that moved around, that the diff overall becomes quite
unreadable and it seemed impossible to recreate the sequence of steps
after the fact.
It all started with adding the parsing for the GPS coordinates. But while
testing that code I found several issues with the rest of the function.
Most importantly it seemed ridiculous that we carefully tried to match the
texts that the DiveObjectHelper would create for the various fields,
instead of just using the DiveObjectHelper to do just that. And once I had
converted that I once again realized just how long and hard to understand
that function was getting and decided to break out some of the more
complex parts into their own helper functions.
But of course all this didn't happen in this logical, structured, ordered
way. Instead I did all of these things at the same time, testing,
rearranging, etc.
So in the end I went with one BIG commit that does all of this in one fell
swoop.
This adds four helper functions to deal with start time/date, duration,
location and gps coordinates, and depth of the dive.
To avoid mistakes when dealing with the GPS coordinates, there's another
helper to encapsulate the creation of the dive site and we switched to a
current GPS location.

If we want to keep the selected dive "close" to where it was before an
operation (whether a delete, or a reload, or something like that), then
the most intuitive thing to do appears to be to select either the same
dive again (if it still exists), or one very close to it in time. This
helper allows us to identify the dive in the current dive list that is
closest to the given time.
We do this in the C code to ensure that we look at all dives in the
dive_table - based on the id that is returned the UI can then figure out
where this dive is currently shown.

John Van Ostrand reports that when he dives using two cylinders using
sidemounts, the per-cylinder SAC rate display is very misleading.
What happens is that since the two cylinders are used together (but
without a manifold), John is alternating between the two but not
actually adding gas switches in the profile. As a result, the profile
looks like only one cylinder is used, even though clearly the other
cylinder gets breathed down too.
The per-cylinder SAC rate calculations would entirely ignore the
cylinder that didn't have gas switch events to it, and looking at the
info window it would look like John had a truly exceptional SAC rate.
But then in the general statistics panel that actually takes the whole
gas use into account, the very different real SAC rate would show up.
The basic issue is that if we don't have full use information for the
different cylinders, we would account the whole dive to just a partial
set. We did have a special case for this, but that special case only
really worked if the first cylinder truly was the only cylinder used.
This patch makes us see the difference between "only one cylinder was
used, and I can use the overall mean depth for it" and "more than one
cylinder was used, but I don't know what the mean depths might be".

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.
