The basic problem was that for gases containing more than 2147483648 ml
of nitrogen the calculations overflowed. This changes the code into
using floating point math for that calculation which will be more

This isn't Cobalt specific, this is specific to dive computers that
indicate the first tank that's in use with a gaschange event that
coincides with the first sample.
We need to make sure that we suppress showing that gas change event
(regardless which cylinder it goes to) and instead set the correct
cylinder index from the very start of the dive.
This works with the test data I have and doesn't seem to break thing with
any of the files that I tried... but I'm worried that this is not the
right way to do things.

The gas use logic in the dive statistics page is confused.
The SAC case had a special case for "unknown", but only for
the first gas. Other gases had the normal empty case.
Also, the logic was really odd - if you had gases that weren't used (or
pressures not known) intermixed with gases you *did* have pressure for,
the statistics got really confused.
The list of gases showed all gases that we know about during the dive,
but then the gas use and SAC-rate lists wouldn't necessarily match,
because the loops that computed those stopped after the first gas that
didn't have any pressure change.
To make things worse, the first cylinder was special-cased again, so it
all lined up for the single-cylinder case.
This makes all the cylinders act the same way, leaving unknown gas use
(and thus SAC) just empty for that gas.
It also fixes the SAC calculation case where we don't have real samples,
and the profile is a fake profile - possibly with gas changes in between
the fake points. We now make the SAC calculations match what we show -
which is admittedly not at all necessarily what the dive was, but at
least we're consistent.

This uses a bit of naive gas computations to figure out how much of

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").

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

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.

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.

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).

style and consistency. Ensure divelist is marked as

Most of the warnings are IMHO false positives:
e.g.: an enum variable is initialized in a switch statement that has a case for
each possible enum value - yet gcc 4.8 warns that it could be used
uninitialized;
or: two variables are initialized together in the code - second one of them
is previously initialized to -1 at declaration time, both are initialized
in an if (second one == -1) clause - so they are guaranteed to both be
initialized...
I did not "fix" those as the code is actually correct.
But there are three spots where it catches things that could indeed go wrong
(with odd input data in one of them).
This commit also adds a check to only call g_type_init() for older versions of
glib as in newer ones it is deprecated.
