This creates a helper function called "gas_volume()" that takes the
cylinder and a particular pressure, and returns the estimated volume of
the gas at surface pressure, including proper approximation of the
incompressibility of gas.
It very much is an approximation, but it's closer to reality than
assuming a pure ideal gas. See for example compressibility at

When starting on this quest to stop using the first divecomputer instead
of data for the whole dive in commit eb73b5a528c8 ("Duration of a dive is
the maximum duration from all divecomputers") I introduced an accessor
function that calculates the dive duration on the fly as the maximum of
the durations in the divecomputers.
Since then Linus and I have added quite a few of the variables back to the
dive data structure and it makes perfect sense to do the same thing for
the duration as well and simply do the calculation once during fixup.
This commit also replaces accesses to the first divecomputer in
likely_same_dive to use the maxdepth and meandepth of the dive (those two
slipped through the cracks in the previous commits, it seems).

While the profile switched between different divecomputers, the Dive Info
notebook always showed either information from the first divecomputer or
(with some of the recent changes) information that had been collected from
all divecomputers and somehow consolidated for the dive.
With this commit we now show the data from the same divecomputer that is
also shown in the profile (which means if some data is available from one
of the divecomputers and not from another that will be correctly reflected
in the Dive Info notebook as the user cycles through the divecomputers.
This does beg the question if we should have some kind of "best data
available, considering all divecomputers" mode - but that's definitely not
something I'll tackle prior to 3.0.

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 generate the average temperature statistics by adding up the
(converted to user unites - not in millikelvin) temperatures and then
dividing by the number of dives we've added up over.
HOWEVER.
We did that summing of the temperatures into an integer variable, even
though the converted temperatures are floating point. So things got
rounded down to integers and the average temperature was just bogus
(although reasonably close).
We could do the summing of the temperatures in millikelvin and only
doing the conversion to the user at the very end. But the smaller patch
is to just change the accumulator to a double value.

Turns out we had a data field for visibility as a length unit - but never
used it. I can never guess how much visibility we actually had on a dive -
but I think most everyone can assign a rating between abysmal (zero stars,
"I couldn't read my dive computer even right in front of my mask" - trust
me, I had some of those dives) to amazing ("five stars, I could see farther
than I though possible" - and I had one or two of those, too). So I
changed this to an integer and am re-using the star infrastructure we have
for the overall dive rating.
When displaying this I was dismayed that we are running out of space in
the "Dive Notes" notbook. So I moved this to the "Dive Info" notebook.
This is not consistent and not logical. I think we need to revisit the
notebooks and think about what we want to display where.
While adding the infrastructure to manually enter the visibility I went
ahead and added the ability to manually enter the air temperature as well
(that was one of the things missing in the previous commit).

This looks like a massive commit mainly because of the line number changes
in the .po files. That sadly hides what really happened here:
- the places where we manually build dates have now been localized
- the one place where we did the English "calculated plural" has been
modified so that it now can be correctly translated (in English this
just adds an 's' to the noun if the number is != 1 - in other languages
this tends to be much more complicated)
I then updated the two German translations to take advantage of the new
constructs. And while I was at it, I changed the translation Trip->Gruppe
to Trip->Reise as that seemed much more appropriate.
I also fixed another error in the German translation where I translated
"dive time" as "Startzeit" - but in the context it was "Dauer".

This is just the first step - convert the string literals, try to catch
all the places where this isn't possible and the program needs to convert
string constants at runtime (those are the N_ macros).
Add a very rough first German localization so I can at least test what I
have done. Seriously, I have never used a localized OS, so I am certain
that I have many of the 'standard' translations wrong. Someone please take
over :-)
Major issues with this:
- right now it hardcodes the search path for the message catalog to be
./locale - that's of course bogus, but it works well while doing initial
testing. Once the tooling support is there we just should use the OS
default.
- even though de_DE defaults to ISO-8859-15 (or ISO-8859-1 - the internets
can't seem to agree) I went with UTF-8 as that is what Gtk appears to
want to use internally. ISO-8859-15 encoded .mo files create funny
looking artefacts instead of Umlaute.
- no support at all in the Makefile - I was hoping someone with more
experience in how to best set this up would contribute a good set of
Makefile rules - likely this will help fix the first issue in that it
will also install the .mo file(s) in the correct place(s)
For now simply run
msgfmt -c -o subsurface.mo deutsch.po
to create the subsurface.mo file and then move it to
./locale/de_DE.UTF-8/LC_MESSAGES/subsurface.mo
If you make changes to the sources and need to add new strings to be
translated, this is what seems to work (again, should be tooled through
the Makefile):
xgettext -o subsurface-new.pot -s -k_ -kN_ --add-comments="++GETTEXT" *.c
msgmerge -s -U po/deutsch.po subsurface-new.pot
If you do this PLEASE do one commit that just has the new msgid as
changes in line numbers create a TON of diff-noise. Do changes to
translations in a SEPARATE commit.
- no testing at all on Windows or Mac
It builds on Windows :-)

Display yearly statistics in a statistics window with option to expand

information like duration, depth, water temperature and air consumption
is displayed in yearly and monthly level. Thus you are able to compare
e.g. development of air consumption or diving activity from year to
year.
Using already existing macro for splitting seconds into minutes:seconds.
Moving repetitive code to a function (couldn't think of the suggested

local for-loop variables. However, gcc needs special command line
options, and other compilers may not do it at all. So instead of doing
#define for_each_dive(_x) \
for (int _i = 0; ((_x) = get_dive(_i)) != NULL; _i++)
we require that the user declare the index iterator too, and the use
syntax becomes
for_each_dive(idx, dive) {
... use idx/dive here ...
}

This completely changes how we keep track of selected dives: instead of
having an array listing the selection ("selectiontracker") or trusting
the gtk selection information, just save the information about whether a
dive is selected in the dive itself.
That makes it trivial to keep track of the state of selection across
group collapse/expand events, or when changing the tree view model. It
also ends up simplifying the code and logic in other ways.
HOWEVER, it does currently (re-)introduce an annoying oddity with gtk:
if you collapse a dive trip that has individual selections, gtk will
forget those selections ("out of sight, out of mind"), and when you do
*new* selections, the old hidden ones remain.
So there's some games required to make gtk do sane things. We may need
to either explicitly drop selections when collapsing trips, or make sure
the group entry gets selected when collapsing a group that has
selections in it. Or something.
There may be other issues introduced by this too.

Previously when only one dive was selected, the Stats notebook page would show
the statistics for all dive. That creates a very illogical behavior when
clicking on the different dive groups in the dive list. The stats page would
always show how many dives where in a group when the group was selected, except
when there was only one dive in the group, in which case the statistics for all
the dives were shown.
With this change we also show the statistics for the selected dives, even if it
is just one. If you want the statistics for all dives, simply select them all
(Ctrl-A or Command-A on a Mac).
Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
We spend way too much effort trying to get gtk to manage the dives that
are selected. The straw that broke the camel's back is that gtk forces us
to expand any nodes that we want to select - so selecting a summary entry
for a dive trip forced us to expand all the dives in the dive trip. Which
as Linus pointed out really sucked from a user experience.
So instead we now completeley ignore gtk's weird idea of what is selected
and what isn't and simply track things ourselves. We still need to play
some games with gtk to make sure that the correct rows are SHOWN as
selected, but still, the overall code seems much cleaner.
This commit contains a bunch of debugging code that is ifdef'ed out -
this is extremely useful to make sure I didn't mess anything up, but
eventually I'll want to remove that again as it just looks ugly in the
code.
