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.
Change the "seen" logic for the cylinder to ignore cylinders that are
only mentioned by other dive computers than the active one.

If we consider the actual time to ascend from the final stop when calculating

we assume it is always the same (take default ascent rate of 9m/min) then
slower the final ascent won't lead to a longer final stop.

We only cleared the first sensor data when we created new synthetic plot
info entries, because we only used to have one (well, we had the o2
data, but apparently nobody ever noticed that it didn't get properly
interpolated, probably because people who have CCR dives with o2
pressures are few, and the pressure drops are gradual anyway).
Clear all the pressure data, so that the interpolation code doesn't

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
with concurrent gas pressure handling support.

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.

"If it hasn't been tested, it doesn't work".
All my testing of the multiple sensor pressures have been with some
reasonably "interesting" dives: they actually *have* sensor pressures.
But that test coverage means that I missed the truly trivial case of
just having manual pressures for a single cylinder.
Because there's only a single cylinder, it doesn't have any cylinder
changes, and because there were no cylinder changes, it never filled in
the use range for that cylinder.
So then it never showed the pressure profile at all.
Duh.

The momentary SAC rate got broken by the multiple ressure handling too,
and always used just the first cylinder.
This uses the new "get_gasmix()" helper to see what you're breathing,
and will do the SAC rate over all the cylinders that contain that gas.
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
not breating from shouldn't have their pressure change. But maybe some
people add their drysuit argon gas to the gas list?
So this may need more work, but it's a step in the right direction.

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 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.
