This is important if in one dive we have the real dive and
a planned version of the dive as different computers using
different sets of cylinders.

When Suunto Vytecs are used in gauge mode they don't record gasmixes.
If a tank pressure sensor is present they nevertheless record the
pressures. This patch handles this situation by assuming the tanks
contain air (and warning the user about this).

When merging a real dive with a planned dive (for comparison),
we should not try to be clever in merging similar cylinders,
rather keep the union of both cylinder sets as the two versions
of the dive might differ in exctly which gas and how much of it
was used.
Increase MAX_CYLINDERS to 20 to make room for this. We warn if we
exceed this number.

Print the ATM pressure and the altitude used for calculation into the resulting diveplan.
Moved this info together with the deco model info below the runtime table.
There is one drawback in this implementation: Altitude will be recalculated from surface pressure and therefore may differ slightly from altitude entered in the UI.

In the cylinder table, the last column ("use") always showed
OC-GAS. Editing was enabled, but the user had to guess to enter
a small integer meaning dilluent or CCR oxygen cylingder. I guess,
nobody has ever done that.
This patch makes this column clickable. A click toggles if the cylinder
is used for planning or not. This wait it is much easier to investigate
the consequences of gas loss on a plan.

We had hardcoded the exact translation of the event numbers. They
haven't changed (although we did have what appears to be a spurious
entry for "non stop time" at the end that libdivecomputer doesn't have
an enum for).
Instead, use an explicit array index initializer array, so that it's
obvious that the two match up (and if the sample event numbers ever
change, we should cope with it gracefully).

New libdivecomputer versions use DC_SAMPLE_GASMIX to indicate a gas
change (which contains the cylinder index we're changing to) rather than
SAMPLE_EVENT_GASCHANGE*.
Unlike the old GASCHANGE model, and despite the name, DC_SAMPLE_GASMIX
does not actually say what the mix is, it only specifies a cylinder
index. We had already extended SAMPLE_EVENT_GASCHANGE2 to have the
cylinder index in the otherwise unused "flags" field, so this is not all
that different from what we used to do.
And subsurface internally already had the logic that "if we know what
the cylinder index is, take the gas mix from the cylinder data", so
we've already been able to transparently use _either_ the actual gas mix
or the cylinder index to show the event.
But we do want to make it an event rather than some sample data, because
we want to show it as such in the profile. But because we are happy
with just the cylinder index, we'll just translate the DC_SAMPLE_GASMIX
thing to the SAMPLE_EVENT_GASCHANGE2 event, and nothing really changes
for subsurface.
libdivecomputer has made other changes, like indicating the initial
cylinder index with an early DC_SAMPLE_GASMIX report, but we've seen
that before too (in the form of early SAMPLE_EVENT_GASCHANGE events), so
that doesn't really end up changing anything for us either.
HOWEVER, one thing that is worth noticing: do *not* apply this patch and
then use an old libdivecomputer library that sends both the
DC_SAMPLE_GASMIX samples _and_ the deprecated SAMPLE_EVENT_GASCHANGE
events. It will all *work*, but since subsurface will take either,
you'll then get duplicate gas mix events.
It's not like that is in any way fatal, but it might be a bit confusing.

This adds tooltips for the equipment tab for each cylinder, showing the
amount of gas used.
When you mouse over the size and working pressure fields, the tooltip will
show the amount of gas used (along with start and end gas volumes). And
when you mouse over the start and end pressures, it will show the start
and end gas volumes, and the Z factor used.
I started doing this because of the gas volume questions in the last day
or two (and a few from a few weeks ago). When even Robert Helling starts
wondering about the effects of compressibility on the SAC calculation, our
numbers are clearly too opaque.
With these tooltips, at least you can see what went into the used gas
calculations, instead of having to add debugging options to print out Z
factors.
[ This patch also adds a "rint()" to get the rounding right in the
gas_volume() function. Although rounding to the nearst milliliter
really doesn't matter, it's the right thing to do after doing FP
calculations ;^]

We have two prefernces determining the deco_mode (BUEHLMANN vs VPMB
vs RECREATIONAL): One for the planner (deco_mode) and one for
displaying dives (display_deco_mode). The former is set in the planner
settings while the latter is set in the preferences.
This patch clears up a confusion which of the two to use by introducing
a helper function that selects the correct variable.

This patch fixes two bugs:

For each stop, this computes an effective gradient factor
that gives the same ceiling. Then, it does linear regression
to find values for GFlow and GFhigh that give a similar deco
profile.
Note that this optimises the average gradient factor. The
runtime however depends strongly at the gradient factor at
the last depth. So we don't necessarily to get the runtime
right.
