The dive list will be changed to an always-sorted list where one can
use binary search.
However, this makes some tests fail, because they only use parse_dive(),
which doesn't do any sorting.
To fix this future problem, sort the tables before performing the tests.
This provides a more realistic setup, as in the actual application,
the dive list will always be sorted on import.

CCRs are different. It does not make sense to compute
a depth dependent SAC. You could compute the rate of O2
consumption but even that is likely wrong (as O2 in the
diluent would enter that as well), so simply don't attempt
it.

We have this odd legacy notion of a divecomputer 'device', that was
originally just basically the libdivecomputer 'EVENT_DEVINFO' report
that was associated with each dive. So it had firmware version,
deviceid, and serial number.
It had also gotten extended to do 'nickname' handling, and it was all
confusing, ugly and bad. It was particularly bad because it wasn't
actually a 'per device' thing at all: due to the firmware field, a dive
computer that got a firmware update forced a new 'device'.
To make matters worse, the 'deviceid' was also almost random, because
we've calculated it a couple of different ways, and libdivecomputer
itself has changed how the legacy 32-bit 'serial number' is expressed.
Finally, because of all these issues, we didn't even try to make the
thing unique, so it really ended up being a random snapshot of the state
of the dive computer at the time of a dive, and sometimes we'd pick one,
and sometimes another, since they weren't really well-defined.
So get rid of all this confusion.
The new rules:
- the actual random dive computer state at the time of a dive is kept
in the dive data. So if you want to know the firmware version, it
should be in the 'extra data'
- the only serial number that matters is the string one in the extra
data, because that's the one that actually matches what the dive
computer reports, and isn't some random 32-bit integer with ambiguous
formatting.
- the 'device id' - the thing we match with (together with the model
name, eg "Suunto EON Steel") is purely a hash of the real serial
number.
The device ID that libdivecomputer reports in EVENT_DEVINFO is
ignored, as is the device ID we've saved in the XML or git files. If
we have a serial number, the device ID will be uniquely associated
with that serial number, and if we don't have one, the device ID will
be zero (for 'match anything').
So now 'deviceid' is literally just a shorthand for the serial number
string, and the two are joined at the hip.
- the 'device' managament is _only_ used to track devices that have
serial numbers _and_ nicknames. So no more different device
structures just because one had a nickname and the other didn't etc.
Without a serial number, the device is 'anonymous' and fundamentally
cannot be distinguished from other devices of the same model, so a
nickname is meaningless. And without a nickname, there is no point in
creating a device data structure, since all the data is in the dive
itself and the device structure wouldn't add any value..
These rules mean that we no longer have ambiguous 'device' structures,
and we can never have duplicates that can confuse us.
This does mean that you can't give a nickname to a device that cannot be
uniquely identified with a serial number, but those are happily fairly
rare (and mostly older ones). Dirk said he'd look at what it takes to
give more dive computers proper serial numbers, and I already did it for
the Garmin Descent family yesterday.
(Honesty in advertizing: right now you can't add a nickname to a dive
computer that doesn't already have one, because such a dive computer
will not have a device structure. But that's a UI issue, and I'll sort
that out separately)

Before making the cylinder-table dynamic, dives always
had at least one cylinger. When such a dive is displayed,
the TabDiveInformation class calls per_cylinder_mean_depth().
If there are no samples, this function generates a "fake
profile" with fake_dc(). Thus, effectively dives always
had samples once the user was displaying them.
When the cylinder-table was made dynamic, dives without
cylinders were supported. This can notably happen, when
importing from CSV (this could actually be a bug).
per_cylinder_mean_depth() exits early in that case and
doesn't create a fake profile. This lead to crashes
of the profile-widget, which were fixed in 6b2e56e513.
Non-sample dives were now shown with the Subsurface-logo.
To restore the previous behavior, genarate a fake profile
for sample-less dives in fixup_dive(), which is called
anytime a dive is loaded or imported. This seems to
have been the intention anyway and this worked only
"by chance". This will make a few fake_dc() calls obsolete,
but so be it.
Since fake profiles are now generated on loading,
the parse-tests need to be fixed to account for that.

Even when diving a CCR, the pO2 cannot exceed ambient
pressure. This only makes a difference at shallow depths.
Fix this in the calculation of OTUs and CNS.
This affects some tests that now have slightly different CNS and OTU values.

We do _not_ read them back, since they are calculated values, although I
guess we could aim to do that too at some point in case we have an
import from somewhere else that has these values but not the profile (or
gas use) to actually calculate them.
Fix test-cases that are checked by TestParse (but nothing else) to match.

The code incorrectly divided the temperature by 10 as an integer,
causing unnecessary precision loss due to truncation.

to match that change to ensure that TestParse passes again.

Also fixed it to correctly parse the mean depth (duh, a test that had a

With no V2 question shown
- parsing fails when a V2 file is loaded
- parsing succeeds when a V3 file is loaded
- import of CSV file succeeds
With V2 question shown
- parsing succeeds when a V2 file is loaded
Finally compare the output of reading in the various files with reference
output included in the sources.
My guess is that this test might be a bit fragile, but hey, it's a start.
