Prior to this change, we had two different cylinder lists as models for
drop down boxes - one that prepends the "no default cylinder" entry
(which we need for setting up no default cylinder to be used in the
app), and another one that only includes actual cylinders.
The problem occured if a dive is created before the first time we edit
an existing dive: in this case we are applying indices across the two
models, but the indices are of course off by one; this results in
actually picking the wrong cylinder. So each time we try to edit a dive,
we end up with the previous cylinder in the list.
This commit simplifies the code by having only one place where we create
list of cylinder names (which is then used as the model for the combo
box). It also uses more logical names for the two 'flavors' of this list
to make it clear which one is supposed to be used (the regular list when
editing or adding dives, the one with the "no default cylinder" entry
prependet for the Settings page).

This does the right thing even when removing a nickname by setting it to

We no longer need the remove infrastructure, and the edit nickname function
becomes much more intuitive to use by passing in the dive computer for
which we want to create a nickname instead of the internal index into
the array of devices.
This also removes / simplifies the device list update signals in the

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.

This adds the menu item to rename a dive computer (ie create a nickname
for it) when right-clicking on the dive computer name of a dive computer
that has a serial number (indicated by having a non-zero ->deviceid).
It is nonfunctional because it's really just the skeleton code: it needs
the UI to actually ask for a new nickname, and then it needs to actually
do the proper "create_device_node(model,serial,nickname)" to set it (or
remove the nickname if empty).

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)

If the last displayed dive had events, those DiveEventItems had slots connected
that would update those icons if things changed. When closing the dive log and
switching to a different one, those slots were still called and would then access
freed memory (the event structure from that old dive that is long gone by then).
This code explicitly deletes those DiveEventItems which also removes those signal
slot connections.

Commit e42fc1a1e9 introduced a
crash condition. Apparently the code attempts to test whether
the clicked-on item is a top-level dive. The "Collapse others"
menu item should not be shown in that case. It does this by
testing "d->divetrip". However, "d" might quite logically be
null if clicking on an unexpanded trip header.
Therefore, check explicitly for the trip header case (which
should show the menu item) and for good measure prevent
the nullpointer access (that should be caught by testing
for trip, but who knows).

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()

later with a different meaning, making this super-confusing.
The membuf variable is turned from "const char *" to "char *"
