This is the second step for implementing bailout. The indirect
calls to fill_pressures through add_segment() (in deco.c) are
addressed. Bailout is now fully implemented in the dive log but
not in the dive planner.
1) The parameters to add_segment() are changed to take a
divemode as the second last parameter, and not a *dive.
2) Call to add_segment() in profile.c and in divelist.c are
adapted. In divelist.c some calls to add_segment were left
using dc-> divemode instead of possible bailout. This appears
tp be the most appropriate route.
3) The functions get_divemode_from_time() and get_next_divemodechange()
in dive.c have had some small changes.
4) The calls to get_segment(0 in planner.c were changed to reflect
the new parameter list, but not updated to reflect bailout. This
is the next step.

This is a first step to interpret bailout events.
1) The event structures have a new attribute: divemode.
Currently interpreted dive modes are OC, CCR, PSCR.
2) When doing fill_pressures(), the calculation is aware
of divemode. When divemode is OC (==bailout), then
the appropriate calculations of gas pressures are done.
3) Two new functions get_next_divemodechange() and
get_divemode_at_time() are created to find divemode
changes in the events linked list and to determine
the dive mode at any point during the dive.
4) fill_pressures gets a small amendment to facilitate
the correct calculations, depending on divemode.
The cases where fill_pressures() is used *outside the planner*
are changed. The result is that, for dives with bailout, the
correct gas pressures are shown on the dive profile. The
deco for bailout dives is not yet correct. This is the
next step.

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

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
deco_time, then slowing the final ascent can lead to the final stop being
extended, which is completely nonsensical. For consistency with the original
VPMB implementation, we can't ignore the final ascent time completely, but if
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
think we have some existing real sensor data for the plot info entries
in between proper sample entries.

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.
