Break the huge calculate_deco_information into three different functions.
One for the current deco calculations, one for the ndl/tts/deco stop and
one for the gas calculations.
This makes it easier to disable/enable different functionality.
This also gets rid if the ccrdive state variable, and keeps that state
in the plot_data struct. Now we calculate the deco before we calculate
the gas properties, so if we have a po2, we're in ccr-mode, and if we
don't, we're in oc mode.

After the 3.1 release it is time to shift the focus on the Qt effort - and
the best way to do this is to merge the changes in the Qt branch into
master.
Linus was extremely nice and did a merge for me. I decided to do my own
merge instead (which by accident actually based on a different version of
the Qt branch) and then used his merge to double check what I was doing.
I resolved a few things differently but overall what we did was very much
the same (and I say this with pride since Linus is a professional git
merger)
Here's his merge commit message:
This is a rough and tumble merge of the Qt branch into 'master',
trying to sort out the conflicts as best as I could.
There were two major kinds of conflicts:
- the Makefile changes, in particular the split of the single
Makefile into Rules.mk and Configure.mk, along with the obvious Qt
build changes themselves.
Those changes conflicted with some of the updates done in mainline
wrt "release" targets and some helper macros ($(NAME) etc).
Resolved by largely taking the Qt branch versions, and then editing
in the most obvious parts of the Makefile updates from mainline.
NOTE! The script/get_version shell script was made to just fail
silently on not finding a git repository, which avoided having to
take some particularly ugly Makefile changes.
- Various random updates in mainline to support things like dive tags.
The conflicts were mainly to the gtk GUI parts, which obviously
looked different afterwards. I fixed things up to look like the
newer code, but since the gtk files themselves are actually dead in
the Qt branch, this is largely irrelevant.
NOTE! This does *NOT* introduce the equivalent Qt functionality.
The fields are there in the code now, but there's no Qt UI for the
whole dive tag stuff etc.
This seems to compile for me (although I have to force
"QMAKE=qmake-qt4" on f19), and results in a Linux binary that seems to
work, but it is otherwise largely untested.

There are two ways to look at surface pressure. One is to say "what was
the surface pressure during that dive?" - in that case we now return an
average over the pressure reported by the different divecomputers (or the
standard 1013mbar if none reported any).
Or you want to do specific calculations for a specific divecomputer - in
which case we access only the pressure reported by THAT divecomputer, if
present (and fall back to the previous case, otherwise).
We still have lots of places in Subsurface that only act on the first
divecomputer. As a side effect of this change we now make this more
obvious as we in those cases pass a pointer to the first divecomputer
explicitly to the calculations.
Either way, this commit should prevent us from ever mistakenly basing our
calculations on a surface pressure of 0 (which is the initial bug in
deco.c that triggered all this).
Similar changes need to be made for other elements that we currently only
use from the first divecomputer, i.e., salinity.

We had this special logic to not show the end of a dive when a dive
computer shows a series of very shallow samples (basically snorkeling
back to shore after the dive ended). However, that logic ended up being
global per dive, which is very annoying when you have two or more dive
computers, and it decides to cut off the second one because the first
one surfaces.
So get rid of this per-dive state, and just use the plot-info 'maxtime'
field for this (we never used the 'start' case anyway). That way we
will properly cut off boring surface entries only when they are past the
end of the interesting entries of *all* dive computers, and we won't be

When we create the event names, the name itself does not include the
information about whether the event is the beginning or end of some
state, so we end up having things like events named "deco" and then in
the event flags it says whether this is the *beginning* of deco, or the
end.
And when we show the event, we only used to show the name. This patch
makes us show whether it's the begin or end event for events that have
those flags. So now you see "deco begin" and "deco end" instead of just
two events both called "deco".
It would perhaps be nice if we somehow showed the range between the
events too, and paired them up visually some way, but that's a separate
and much more difficult thing to do.

This adds the GFlow/high values used to calculate the ceiling (if any).
Right now it shows those numbers even if at no point of the dive there was
an actual ceiling (but only if showing the ceiling itself is enabled).
This should make it easier to for the user to make sense of the calculated
ceiling, especially if posting screen shots.
As an aside - for some dive computers like the OSTC and the Shearwaters we
should be able to also plot the GF used by its calculation which might be
interesting for comparison purposes, as both of them also give us the
ceiling (lowest deco stop) calculated during the dive..

This made sense briefly when libdivecomputer reported ceiling data through
events with those flags, but it actually made us hide valid events from
some divecomputers that give us only very limited information (e.g., deco
events from some Suunto divecomputers).

The plot-info per-event 'same_cylinder' logic was fragile, and caused
us to not print the beginning pressure of the first cylinder.
In particular, there was a nasty interaction with not all plot entries
having pressures, and the whole logic that avoid some of the early
plot entries because they are fake entries that are just there to make
sure that we don't step off the edge of the world. When we then only
do certain things on the particular entries that don't have the same
cylinder as the last plot entry, things don't always happen like they
should.
Fix this by:
- get rid of the computed "same_cylinder" state entirely. All the
cases where we use it, we might as well just look at what the last
cylinder we used was, and thus "same_cylinder" is just about testing
the current cylinder index against that last index.
- get rid of some of the edge conditions by just writing the loops
more clearly, so that they simply don't have special cases. For
example, instead of setting some "last_pressure" for a cylinder at
cylinder changes, just set the damn thing on every single sample. The
last pressure will automatically be the pressure we set last! The code
is simpler and more straightforward.
So this simplifies the code and just makes it less fragile - it
doesn't matter if the cylinder change happens to happen at a sample
that doesn't have a pressure reading, for example, because we no
longer care so deeply about exactly which sample the cylinder change
happens at. As a result, the bug Mika noticed just goes away.

Commit b625332ca5ff "Display even constant temperature graph" was a little
too aggressive. If we have no temperature data at all it caused us to plot
a temperature line for absolute zero...

Dive profile does not display the temperature graph, if we have a
constant temperature (e.g. only one reading at the start of the dive).
This patch draws the temperature graph even if max and min temperatures
are the same.

Temperatures can actually be negative, which means that rounding by
adding 0.5 and casting to 'int' is not correct.
We could use '(int)(rint(val))' instead, but the only place we care
about might as well just print out the floating point representation
with a precision of two digits instead. So if you have a dive computer
that gives you the precision, you might see '3.5˚C' as the temperature.
Remove the helper functions that nobody uses and that get the rounding
wrong anyway.

This moves the fields 'duration', 'surfacetime', 'maxdepth',
'meandepth', 'airtemp', 'watertemp', 'salinity' and 'surface_pressure'
to the per-divecomputer data structure. They are filled in by the dive
computer, and normally not edited.
NOTE! All actual *use* of this data was then changed from dive->field to
dive->dc.field programmatically with a shell-script and sed, and the
result then edited for details. So while the XML save and restore code
has been updated, all the displaying etc will currently always just show
the first dive computer entry.

This patch centralizes the definition for surface pressure, oxygen in
air, (re)defines all such values as plain integers and adapts calculations.
It eliminates 11 (!) occurrences of definitions for surface pressure and
also a few for oxygen in air.
It also rewrites the calculation for EAD, END and EADD using the new
definitons, harmonizing it for OC and CC and fixes a bug for EADD OC
calculation.
And finally it removes the unneeded variable entry_ead in gtk-gui.c.

Previously we calculate the ceiling at every single second, using the
interpolated depth but then only *save* the ceiling at the points where we
have a profile event (the whole deco_allowed_depth() function doesn't
change any state, so we can just drop it entirely at points that we aren't
going to save)
Why is it incorrect? I'll try to walk through my understanding of it, by
switching things around a bit.
- the whole "minimum tissue tolerance" thing could equally well be
rewritten to be about "maximum ceiling". And that's easier to think
about (since it's what we actually show), so let's do that.
- so turning "min_pressure" into "max_ceiling", doing the whole
comparison inside the loop means is that we are calculating the
maximum ceiling value for the duration of the last sample. And then
instead of visualizing the ceiling AT THE TIME OF MAXIMUM CEILING, we
visualize that maximal ceiling value AT THE TIME OF THE SAMPLE.
End result: we visualize the ceiling at the wrong time. We visualize
what was *a* ceiling somewhere in between that sample and the previous
one, but we then assign that value to the time of the sample itself.
So it ends up having random odd effects.
And that also explains why you only see the effect during the ascent.
During the descent, the max ceiling will be at the end of our
linearization of the sampling, which is - surprise surprise - the position
of the sample itself. So we end up seeing the right ceiling at the right
time while descending. So the visualization matches the math.
But during desaturation, the maximum ceiling is not at the end of the
sample period, it's at the beginning. So the whole "max ceiling" thing has
basically turned what should be a smooth graph into something that
approaches being a step-wise graph at each sample. Ergo: a ripple.
And doing the "max_ceiling during the sample interval" thing may sound
like the safe thing to do, but the thing is, that really *is* a false
sense of safety. The ceiling value is *not* what we compute. The ceiling
value is just a visualization of what we computed. Playing games with it
can only make the visualization of the real data worse, not better.

- MOD: Maximum Operation Depth based on a configurable limit
- EAD: Equivalent Air Depth considering N2 and (!) O2 narcotic
- END: Equivalent Nitrogen (Narcotic) Depth considering just N2 narcotic
(ignoring O2)
- EADD: Equivalent Air Density Depth
Please note that some people and even diving organisations have opposite
definitions for EAD and END. Considering A stands for Air, lets choose the
above. And considering N for Nitrogen it also fits in this scheme.
This patch moves N2_IN_AIR from deco.c to dive.h as this is already used
in several places and might be useful for future use also. It also
respecifies N2_IN_AIR to a more correct value of 78,084%, the former one
also included all other gases than oxygen appearing in air. If someone
needs to use the former value it would be more correct to use 1-O2_IN_AIR
instead.
