920ff15f71 Planner: don't return static data in fake_dc()
fake_dc() used to return a statically allocated dc with statically
allocated samples. This is of course a questionable practice in
the light of multi-threading / resource ownership. Once these
problems were recognized, the parameter "alloc" was added. If set
to true, the function would still return a statically allocated
dc, but heap-allocated samples, which could then be copied in
a different dc.

All in all an ownership nightmare and a recipie for disaster.
The returned static dc was only used as a pointer to the samples
anyway. There are four callers of fake_dc() and they all have access
to a dc-structure without samples. Therefore, change the semantics
of fake_dc() to fill out the passed in dc. If the caller does
not care about the samples, it can simply reset the sample number
to zero after work.

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

f1830cd44e Profile: On dataChanged() only update pictures that actually changed
Only update those pictures of the DivePictureModel that actually changed.
This will be useful once pictures are loaded incrementally.

To do so, replace the pictures array by an array with stable ids. Before
this commit, not-shown pictures are left out of the pictures array, which
makes the mapping from DivePictureModel-ids to the picture array index
non-trivial.

Replace the QList<DivePictureItem *> by a std::vector<std::unique_ptr<DivePictureItem>>
to ease memory management. Sadly, owing to COW semantics, QVector is incompatible
with QScopedPointer.

20dc6a31f4 profile: replot handles while planning
The settingsChanged() function of the profile widget tries to be
clever and tries to prevent not needed replots of the profile.
I'm not sure this is very relevant in the first place as change
of settings are almost instantly, with or without replot. It
appears that replot is always executed when there are
calculated ceilings visible. But without calculated ceilings
a replot is "optimized out". This does, however, introduce dangling
divehandles in PLAN/EDIT and ADD mode of the profile, when
any setting that influences the y-axis is changed.

The fix is trivial. Just force a replot in the PLAN/EDIT and ADD
modes.

b4d37e8eeb profile: fix garbled profiles after visiting the planner
See mentioned GitHub issue for the full issue, and images.

The reason for this weird behavior is the existence of 2 flags in
the profile code: shouldCalculateMaxTime and shouldCalculateMaxDepth.
When exactly following the use case and test data as attached to
the GitHub issue (a very short dive, shorter than most of the
dives in the logbook), the shouldCalculateMaxTime flag never got
back to its true status, causing the the time scale not to adapt
to other dives when just clicking (or selecting) them from the dive
list.

The problem is fixed here by also setting the shouldCalculateMaxTime
flag on manipulating wayppoints in the dive plan.

05a1626c7e Implement different zoom levels for dive photos tab
This implements different zoom levels for the dive photos tab as
suggested by Stefan Fuchs <sfuchs@gmx.de> in #898.
The zoom level can be changed using a slider or CTRL+mousewheel.
Zoom levels range from a third of the standard thumbnail size to
thrice the standard thumbnail size.

Thumbnails are cached in maximum resolution and scaled down on
the fly. Because the profile widget took its pictures from the
photo list model, an extra picture copy with a fixed size had
to be introduced.

The UI is still a bit crude.

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.

bd0c99dfb7 MOBILE: Display pO2 and Setpoint for CCR dives
For CCR dives we want to display the setpoint and pO2 information,
due to the limited screensize we have to remove the temperature graph or
the view will be to cluttered.

597539ce39 Fix double to int truncation in C++ code
Wfloat-conversion enabled for C++ part of the code
Fix warnings raised by the flag using lrint

Original issue reported on the mailing list:
The ascent/descent rates are sometimes not what is expected.
E.g. setting the ascent rate to 10m/min results in an actual
ascent rate of 9m/min.
This is due to truncating the ascent rate preference,
then effectively rounding up the time to reach each stop to 2s intervals.
The result being that setting the ascent rate to 10m/min
results in 20s to ascend 3m (9m/min), when it should be exactly 18s.
