This assumes that you are not breathing your cylinders while at the
surface, which may or may not be correct, but is usually the right
thing. Regardless, we're better off giving a conservative (higher) SAC
rate estimate for a diver that breathes his cylinder at the surface too
than giving an artificially low one because the diver ended up using his
snorkel and we didn't take that into account.
NOTE! This basically calculates a better duration and average depth than
the ones we end up showing in the dive list. Maybe we should actually
show this "no-surface-time" duration and average depth instead of the
ones we do show?
That's a separate question, though.
Added a test-case for the surface case to the sac-test.xml dives.

We even documented that we did SAC in bar*l/min, but the "S" in SAC
stands for "Surface". So we should normalize SAC rate to surface
pressure, not one bar.
It's a tiny 1% difference, and doesn't actually matter in practice, but
it's noticeable when you want to explicitly test for SAC-rate by
creating a test-dive that averages exactly 10m. Suddenly you don't get
the round numbers you expect.
[ Side note: 10m is not _exactly_ one extra atmosphere according to our
calculations, but it's darn close in sea water: the standard salinity
of 1.03 kg/l together with the standard acceleration of 9.81m/s^2
gives an additional pressure of 1.01 bar, which is within a fraction
of a percent of one ATM.
Of course, divers have likely chosen that value exactly for the math
to come out that way, since the true average salinity of seawater is
actually slightly lower ]
So here's a few test-dives, along with the SAC rate fixup to make them
look right.
(There's also a one-liner to dive.c that makes the duration come out
right if the last sample has a non-zero depth, and the previous sample
did not: one of my original test-dives did the "average 10m depth" by
starting at 0 and ending at 20m, and dive.c got a tiny bit confused
about that ;)
[ The rationale for me testing our SAC rate calculations in the first
place was that on snorkkeli.net user "Poltsi" reported that our SAC rate
calculations differ from the ones that Suunto DM4 reports. So I wanted
to verify that we did things right.
Note that Poltsi reported differences larger than the difference of
BAR/ATM, so this is not the cause. I'll continue to look at this. ]

Someone who is better at shell script writing needs to review this.
Here's what it's supposed to do. Create version strings with three or four
values for darwin or win, respectively, that we can use as the versions of
the bundle or installer. The version that Subsurface reports isn't
affected by this. So in a way this is automating something that's mostly
cosmetic.
If we have a 2 digit version number (like 3.0), do the same the old script
did - add just zeroes if we are on a tag, otherwise add the number of
commits since the tag (and a last 0 if on win).
If we have a 3 digit version numner (like 3.0.1), leave it alone on mac
and add either the number of commits since the tag or a zero if we are on
the tag on win.
Now this can create the same version number for two different versions on
darwin: the first commit after 3.0 and the version tagged as 3.0.1 will
both get the same number. That's kinda silly but remember - the non-tagged
versions aren't supposed to be widely distributed (and the third digit in
them should be much larger than anything we'd ever release; we are
already on commit 16 since the last tag and hopefully will never release a
3.0.16 as tagged release). And of course the full version as displayed in
the About box is always able to tell things apart because of the SHA added
at the end if it's a non-tagged version.
So why all this magic? The reason we do this is so that during development
we are able to create Mac and Windows installers and they get reasonable
version numbers, based on the versioning that these vendors suppose. And
without manual intervention.

The problem is that when we reach the gas change depth and compute the
stop time, no gas change event is created yet but time_at_last_depth tries
to determine the gas for the stop from events.
So instead we pass o2 and he as parameters of that function and calculate
the wait time based on that information.

Wipping it out makes unnecesary the *2 divisor.
As there may be wrapped strings in tank we need to take

Commit 28aba5a206 ("Flesh out the UDDF xml parsing a bit more")
improved on parsing UDDF files by teaching "percent()" to also handle
pure fractions like UDDF uses. So in a UDDF file, an o2 value of "1.0"
means "100%".
But it turns out that I have a few dives with "1% He", and the "Turn
fractions into percent" logic also turns that into 100%.
So this makes the 'percent()' function a bit smarter. If it actually
finds a percentage-sign after the number, it knows it is already
percent, not a fraction. That disambiguates the two cases: "1.0" is
100%, but "1.0%" (note the explicit percentage sign) is 1%.
So now our native format cannot get confused, because it generally
tries to avoid naked numbers. Good choice.

This uses the example UDDF file from Jan Schubert's Heinrichs Weikamp
DR5 dives, and now parses the dive dates, the cylinder mixes and the gas
switch events correctly (or at least partially).
It's not perfect: the gas mix has an "id" field that we ignore, and
instead we just depend on the cylinders being in order (which they seem
to be). And I have rather limited test-cases, so maybe something else
is messed up too. But for the six example dives I have, this gives
reasonable data.
