All accesses to the pressure data were converted to use functions.
Therefore it is now rather trivial to dynamically allocate the
pressure array and just change the functions.
The only thing to take care of is the idiosyncratic memory
management. Make sure to free and copy the buffer in the
appropriate places.

Continue with replacing pointers to struct plot_data entries
by indexes. Thus the pressure data can be kept in its own
array and can by dynamically sized.

The goal here is to make it possible to detach the pressure related
data from the plot_info structure. Thus, the pressure related data
can be allocated independently depending on the number of cylinders
per dive.

The create_plot_info_new() function releases old plot data. This
can only work if the plot_info structure was initialized previously.
The ProfileWidget2 did that by a memset, but other parts of the code
did not.
Therefore, introduce a init_plot_info() function and call that when
generating a plot_info struct. Constructors would make this so much
easier - but since this is called from C, we can't use them.

Replace the INTERPOLATED_PRESSURE and SENSOR_PRESSURE macros by
inline functions. Generate a common inline function that reads
a pressure value for a dynamic sensor.
Not all SENSOR_PRESSURE macros can be replaced, because the

All callers of create_plot_info_new() called calculate_max_limits_new()
a line before. Thus, simply call the latter in the former.
This allows us to automatically free the plot data in create_plot_info_new().

There was a global variable last_pi_entry_new, which stored the
recently allocated plot data. This was freed when new plot data
was generated.
A very scary proposition: You can never have two plot datas at
the same time! But exactly that happens when you export for
example subtitles.
The only reason why this didn't lead to very crazy behavior
is that at least on my Linux machine, the calloc() call would
just return the previously freed memory.
Fix this mess by removing the global variable and freeing the
data in the callers.

This is another entry in the series to make more things
"const-clean" with the ultimate goal of merge_dive() take
const pointers.
This concerns functions taking pointers to events and
the fallout from making these const.
The somewhat debatable part of this commit might be
that get_next_event() is split in a two distinct
(const and non-const) versions with different names,
since C doesn't allow overloading. The linker should
recognize that these functions are identical and remove
one of them.

This commit allows plotting the OC-equivalent pO2 graph for PSCR
dives. This happens in both the cases where there is no external
O2-monitoring AND when there is external pO2 monitoring. The
calculations are only done for PSCR dives and is achieved as
follows:
1) Within plot-info create a pressure-t called OC_pO2 in
profile.h and populate this variable with the open-circuit
pO2 values in profile.c.
2) Create a new partialPressureGasItem ocpo2GasItem in
profilewidget2.h and, in profilewidget2.cpp, initialise it
to read the plot-info OC_pO2 values and enable its
display by using the setVisible method. The
diveplotdatamodel was also touched in order to achieve
this.
3) Create a pref button that controls the display of OC-pO2 for SCR dives
4) Change the colour of the OC-pO2 grpah to orange
5) Change the connection of the crr_OC_pO2 signal to be appropriate
6) rename the OC_pO2 attribute to scr_OC-pO2

For UI responsiveness, we need to be able to run the planner in the background. This needs the
planner state to be localized (and we need to pass a pointer around).
In order to not let too many lines overrun (and to save typing in the future)
I have renamed instances of struct deco_state to ds. Yes this should have gone
to a separate commit but I accidentally commit --amend'ed it.
Computing of planner variations is temporarily disabled.
Unlock the planner when returning early
So we don't deadlock in add dive and recreational mode (which
use the planner without actually planning).

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.

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.
