When planning a dive, the dive could use more gas than is in the cylinder.
So getting a negative end pressure is a useful indication to the user that
there plan might not be a good one.

The logic of removing the event was in the UI, and this makes
the code harder to test because we need to take into account
also the events that the interface is receiving, instead of
only relying on the algorithm to test.
so, now it lives in dive.h/.c and a unittest is easyer to make.

When we merge two dives into the same dive because a divecomputer had
incorrectly considered it two separate dives (due to surface time within
the dive) we should pick the dive ID from the later dive to be the
diveid of the resulting merged dive. Otherwise we might re-download the
(now merged) partial dive.
This is a rather unusual special case, but it actually hit me with the
Uemis on my last dive in Palau: Chandelier Cave has multiple surface
points where you can spend time admiring the cave above water, and the
Uemis (but not my Suunto's) decided that the dive was actually four
short dives back-to-back.

When merging dives, if we know for sure that the dive computers are
different, don't merge them into one (by interleaving the data), but
instead keep both as separate dive computers in the same dive.
This fixes a bug when due to a faulty download the same dive from two dive
computers looks quite different. They don't get merged automatically
(which is fine - they are quite different), but when manually merging
them, we of course want one dive with two dive computers, not one dive
with one merged dive computer.

So this is totally unrelated to the git repository format, except for
the fact that I noticed it while writing the git saving code.
The subsurface divetag list handling is being stupid, and has a
initial dummy entry at the head of the list for no good reason.
I say "no good reason", because there *is* a reason for it: it allows
code to avoid the special case of empty list and adding entries to
before the first entry etc etc. But that reason is a really *bad*
reason, because it's valid only because people don't understand basic
list manipulation and pointers to pointers.
So get rid of the dummy element, and do things right instead - by
passing a *pointer* to the list, instead of the list. And then when
traversing the list and looking for a place to insert things, don't go
to the next entry - just update the "pointer to pointer" to point to
the address of the next entry. Each entry in a C linked list is no
different than the list itself, so you can use the pointer to the
pointer to the next entry as a pointer to the list.
This is a pet peeve of mine. The real beauty of pointers can never be
understood unless you understand the indirection they allow. People
who grew up with Pascal and were corrupted by that mindset are
mentally stunted. Niklaus Wirth has a lot to answer for!
But never fear. You too can overcome that mental limitation, it just
needs some brain exercise. Reading this patch may help. In particular,
contemplate the new "taglist_add_divetag()".

This saves the dive data into a git object repository instead of a
single XML file.
We create a git object tree with each dive as a separate file,
hierarchically by trip and date.
NOTE 1: This largely duplicates the XML saving code, because trying to
share it seemed just too painful: the logic is very similar, but the
details of the actual strings end up differing sufficiently that there
are tons of trivial differences.
The git save format is line-based with minimal quoting, while XML quotes
everything with either "<..\>" or using single quotes around attributes.
NOTE 2: You currently need a dummy "file" to save to, which points to
the real save location: the git repository and branch to be used. We
should make this a config thing, but for testing, do something like
this:
echo git /home/torvalds/scuba:linus > git-test
to create that git information file, and when you use "Save To" and
specify "git-test" as the file to save to, subsurface will use the new
git save logic to save to the branch "linus" in the repository found at
"/home/torvalds/scuba".
NOTE 3: The git save format uses just the git object directory, it does
*not* check out the result in any git working tree or index. So after
you do a save, you can do
git log -p linus
to see what actually happened in that branch, but it will not affect any
actual checked-out state in the repository.

rint() is "round to nearest integer", and does a better job than +0.5
(followed by the implicit truncation inherent in integer casting). We
already used 'rint()' for values that could be negative (where +0.5 is
actively wrong), let's just make it consistent.
Of course, as is usual for the messy C math functions, it depends on the
current rounding mode. But the default round-to-nearest is what we want
and use, and the functions that explicitly always round to nearest
aren't standard enough to worry about.

Some dive computers will always download all tanks that they store, not
just the ones used in a dive. Most people only want to see the tanks that
they actually used during the dive (and for the others there's an option
to go back to the old behavior, just in case).
All this is only in memory / during runtime. If the dive computer provided
the extra data we will not throw it away.

When the user asks to merge dives in the divelist, we would always use
the "try tp find matching dive computers and merge at an offset" model.
That is incorrect if the intent is to actually merge two *identical*
dives (with different dive computers), as opposed to merging two short
dives into one longer one with a surface interval.
Normally this doesn't ever trigger (the "same dive" merging will have
been done automatically after downloading from the dive computer), but
if the dive computer times are off, and the user fixes them, and then
asks to merge dives, we should use the non-offset dive merging logic.
We already have that "likely_same_dive()" function that is used to
determine when downloaded dives get merged, so just use it for the user
merge case too.

possible for this function to be called with no dive selected,
initializing pd to NULL is cheap insurance in case that does happen for

This is a bit painful, but we basically walk the samples and pick the
valid tank from the events. And then we do a simple discrete integration
to figure out the mean depth per tank and duration per tank. And then we
assemble all that into per tank statistics.
Strangely the value calculated here seems slightly higher than one would
expect from the overall SAC rate. This inconsistency should be
investigated a bit further, but my guess it it's based on the assumption
that the DC provided mean depth is possibly more accurate than what we can
calculate from the profile.
