0c5ec1d6db Don't calculate SAC-rates for negative pressure changes
They happen - maybe the cylinder actually warmed up, or maybe the user
entered just a ending pressure without a starting pressure.  Regardless,
just ignore cylinder pressure changes that go up.

Also ignore cylinders with a zero ending pressure: that's really a
*missing* pressure rather than an actual zero pressure.  As Dirk says,
the scuba regulators don't even work without a healthy positive pressure
differential, so even when you breathe down a tank to "empty", it won't
be at zero pressure (this is true even with gauge pressure, where zero
means "atmospheric pressure").

33391a77e9 Convert the C code to using stdbool and true/false
Earlier we converted the C++ code to using true/false, and this converts
the C code to using the same style.

We already depended on stdbool.h in subsurfacestartup.[ch], and we build
with -std=gnu99 so nobody could build subsurface without a c99 compiler.

               stdbool.h for C++]

193d20c479 Next step towards working translations
This may seem like a really odd change - but with this change the Qt tools
can correctly parse the C files (and qt-gui.cpp) and get the context for
the translatable strings right.

It's not super-pretty (I'll admit that _("string literal") is much easier
on the eye than translate("gettextFromC", "string literal") ) but I think
this will be the price of success.

f3f7bf51fa Merge branch 'Qt'
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.

ed3f67bc33 Add dive tags and support invalid dives
This started out as a way to keep dives in the dive list but being able to
mark them as 'invalid' so they wouldn't be visible (with an option to
disable that feature).

Now it supports an (at this point, fixed) set of tags that can be assigned
to a dive with 'invalid' being just one of them (but one that is special
as it gets some additional support for hiding such dive and marking dives
as (in)valid from the divelist).

or:   two variables are initialized together in the code - second one of them

0129192958 Try to capture some more potential buffer overflows caused by localization
A couple of these could clearly cause a crash just like the one fixed by
commit 00865f5a1e1a ("equipment.c: Fix potential buffer overflow in
size_data_funct()").

One would append user input to fixed length buffer without checking.

We were hardcoding the (correct) max path length in macos.c - replaced by
the actual OS constant.

But the vast majority are just extremely generous guesses how long
localized strings could possibly be.

Yes, this commit is likely leaning towards overkill. But we have now been
bitten by buffer overflow crashes twice that were caused by localization,
so I tried to go through all of the code and identify every possible
buffer that could be affected by this.

The reason for the check whether the stats_w widget has been populated is
that at the very beginning, when the UI is still being assembled, a first

point the stats_w widget is still empty which tells us that we aren't

b9865d6bbc Move duration to dive structure and replace accessor function
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).

0755cc522b Show the actice divecomputer's data in the Info notebook
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.

b8c7992bbf Improve calculation of maxtemp and mintemp of dive
The existing code only populated the maxtemp based on the samples of a
dive and then in statistics.c checked if there was no such temperature and
replaced it with the water temperature of the first divecomputer.

It makes much more sense to add the water temperature information in every
divecomputer to the min / max calculation during the dive fixup phase.

b286ea638c Simplify/clarify the get_surface_pressure_in_mbar() function
Instead of maintaining a rolling average and re-calculating it at each
stage, just calculate the surface_pressure average the natural way: as
the sum divided by the number of entries.

This results in a single rounding, rather than doing rounding multiple
times and possibly rounding wrong as a result.

Not that we care all that deeply about the LSB of the mbar value, but
the code is simpler and more obvious this way too.
