We no longer need the remove infrastructure, and the edit nickname function

When we save the divecomputer data, we never actually save the serial
value as a field. We used to rely on saving the very dodgy 'deviceid',
and then look up the serial number from there. And that never really
worked reliably, but we didn't really notice, because we never really
_used_ the serial number anywhere.
The only place the serial number is actually reliably displayed is in
the "Extra data" tab, which contains the key value pairs, and that's
where the original dive download code got the serial number from.
So just parse that at load time too, the same way we parsed it at dive
download time.
In fact, do the firmware version the same way, and remove the code from
the downloader, since it too can rely on 'add_extra_data()' just picking
up the information directly.

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.

When merging two dives, the higher CNS value was taken. This could
result in inconsistent CNS values if two dives were merged where
one dive's CNS was calculated from a "fake profile", i.e. a dive
without dive-computer profile. In that case, the most conservative
value (all time spent at the bottom) was assumed. The merged dive
then consisted of the dive-computer profile and the conservative
CNS estimate.
This is fixed by setting the CNS value to "0" after merging,
which means "unknown". The correct value will then be recalculated
in "fixup_dive" from the actual sample data.

The data of the membuffer is passed as a data/length pair
to xmlReadMemory(). There is no point in NUL-terminating it.
Moreover, pass the data directly to xmlReadMemory()
instead of via variables. These variables are reused
later with a different meaning, making this super-confusing.
The membuf variable is turned from "const char *" to "char *"

By default, the parser would create samples with cylinder

common one-cylinder (or even no-cylinder) dives. These
were harmless when the cylinder-table was of a fixed size.

actual out-of-bound accesses. Don't create such samples
in the parser.

The backend infrastructure will soon be able to support more than one
cloud server which automagically stay in sync with each other.
One critical requirement for that to work is that once a session was
started with one of the servers, the complete session happens with that
server - we must not switch from server to server while doing a git
transaction. To make sure that's the case, we aren't trying to use DNS
tricks to make this load balancing scheme work, but instead try to
determine at program start which server is the best one to use.
Right now this is super simplistic. Two servers, one in the US, one in
Europe. By default we use the European server (most of our users appear
to be in Europe), but if we can figure out that the client is actually
in the Americas, use the US server. We might improve that heuristic over
time, but as a first attempt it seems not entirely bogus.
The way this is implemented is a simple combination of two free
webservices that together appear to give us a very reliable estimate
which continent the user is located on.
api.ipify.org gives us our external IP address
ip-api.com gives us the continent that IP address is on
If any of this fails or takes too long to respond, we simply ignore it
since either server will work. One oddity is that if we decide to change
servers we only change the settings that are stored on disk, not the
runtime preferences. This goes back to the comment above that we have to
avoid changing servers in mid sync.
