ae299d5e66 profile: use C++ string functions to format plot data
This may appear a bit ominous, as it doesn't generate a string,
but a vector of strings (one for each line). However, that is
in preparation for the QtQuickification of the profile, where
the text-items take such a list.

e794efaba6 Allow for more O2 sensors
The Divesoft Liberty has four O2 sensors. So far, we had a hard coded
limit of three sensors and crashed with a failed assert when we
encoutered more than three. This allows for up to
MAX_O2_SENSORS which is currently 6. The voting logic is adapted
accordingly: We sort the values and we keep deleting the values that
differ more than 20% by value from the closest. This follows what
Shearwater implements on their computers.

In some of the import/export functions the value is still hard
coded to 6 thanks to explicit field names.

f9b9582a64 core: fold display.h into profile.h
The only things in display.h were profile related, so the
split between these two files is not comprehensible.
In fact profile.h includes display.h, because it needs the

2645fa1495 profile: remove fast argument of create_plot_info_new()
This prevented calculation of the pressure data when dragging
planner handles. However, this lead to weird artifacts.

As an alternative, if this turns out to be too slow, we might
disable the plotting of the pressure curves instead.

That said, even on my super-slow fanless laptop, this performs
reasonably.

725fda3cd1 profile: don't add excessive depth
The old get_maxdepth() function in profile.c was accounting for
two things:
- the partial pressure graphs
- rounding to sane value

Both are now taken care of by the profile itself. This leads to
excessive max-depths. Remove the code from profile.c.

9fd531dcc5 Round gas depth properly
The D in MOD, EAD, END, and EADD stands for "depth" and
as such these should be mm in int rather than double.

The intermediate fn2 and fhe2, however, as intermediate
value should not be rounded to an integer.

The upshot of this is a litle more numerical stability.
It should lead to more stable values in TestProfile
when run on architectures with different floating
point precision.

9bfc6d2520 profile: use a parameter to determine planner state
The in_planner() function is incompatible with a reentrant
profile, since it accesses a global variable. In
create_plot_info_new() it is essentially redundant, because
there is a planner_ds (ds = deco_state) parameter that
is used only when in the planner. Therefore use that as
the in_planner indicator: when non-null, the profile is
showing a planned dive.

4ec88aa564 profile: fix displaying of profiles with multiple pressure sensors
When removing the MAX_CYLINDERS restriction, the layout of the
pressure readings was changed from a (cylinder,sample) to a
(sample,cylinder) scheme. I.e. previously there were one cylinder
block for each sample, then one sample block for one cylinder.

However, after populating the samples, the array size was reduced
to the actual number of used samples. With the new layout this
breaks indexing. Therefore, restore the old layout.

25b30da244 Profile: properly initialize plot_info structures
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.

69be1e23f2 Cleanup: fix memory management of the plot data
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.

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

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

since C doesn't allow overloading. The linker should

81a812539c Plot OC-pO2 graph for SCR dives
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

e1b880f444 Profile support for multiple concurrent pressure sensors
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.

1e38d9239a Start cleaning up sensor indexing for multiple sensors
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.

11a0c0cc70 Unify sample pressure and o2pressure as pressure[2] array
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.
