This introduces a "struct membuffer" abstraction that you can write
things into, and makes the XML saving code write to the memory buffer
rather than a file.
The UDDF export already really wanted this: it used to write to a file,
only to then read that file back into memory, delete the file, and then
*rewrite* the file after doing the magic xslt transform.
But the longer-term reason for this is that I want to try to write other
formats, and I want to try to share most helpers. And those other
formats will need this memory buffer model.

This data structure was quite fragile and made 'undo' when editing
rather hard to implement. So instead I decided to turn this into a
QMultiMap which seemed like the ideal data structure for it.
This map holds all the dive computer related data indexed by the model. As
QMultiMap it allows multiple entries per key (model string) and
disambiguates between them with the deviceId.
This commit turned out much larger than I wanted. But I didn't manage to
find a clean way to break it up and make the pieces make sense.
So this brings back the Ok / Cancel button for the dive computer edit
dialog. And it makes those two buttons actually do the right thing (which
is what started this whole process). For this to work we simply copy the
map to a working copy and do all edits on that one - and then copy that
over the 'real' map when we accept the changes.

Rename gtk-gui.c to qt-gui.cpp, and make the necessary changes so that
the project still builds.

We used to save dive computer information only if that dive computer was
actually used in any of the dives we saved. But we can simplify the
code if we just always save any dive computers we know about. And it
does allow for some usage cases where you have nicknames for other
peoples computers that you may not actively use, but you want to see if
you end up loading multiple XML files in one go.
So there's just no compelling reason to not just save all the info we
have. And this will make it less painful to remove the "use system
config for dive computer nicknames", because you can also use this to
continue to gather dive computer info in a separate XML file if you want
to.

This allows users to edit one or more nick name entries in a single
session. Entries can also be removed individually.
Based on mock up by Lubomir Ivanov and various conversations from Dirk.
Thanks to both.

It turns out that the serial number returned by libdivecomputer isn't
really the serial number as interpreted by the vendor. Those tend to be
strings, but libdivecomputer gives us a 32bit number.
Some experimenting showed that for the Suunto devies tested the serial
number is encoded in that 32bit number:
It so happens that the Suunto serial number strings are strings that have
all numbers, but they aren't *one* number. They are four bytes
representing two numbers each, and the "23500027" string is actually the
four bytes 23 50 00 27 (0x17 0x32 0x00 0x1b). And libdivecomputer has
incorrectly parsed those four bytes as one number, not as the encoded
serial number string it is. So the value 389152795 is actually hex
0x1732001b, which is 0x17 0x32 0x00 0x1b, which is - 23 50 00 27.
This should be done by libdivecomputer, but hey, in the meantime this at
least shows the concept. And helps test the XML save/restore code.
It depends on the two patches that create the whole "device.c"
infrastructure, of course. With this, my dive file ends up having the
settings section look like this:
<divecomputerid model='Suunto Vyper Air' deviceid='d4629110'
serial='01201094' firmware='1.1.22'/>
<divecomputerid model='Suunto HelO2' deviceid='995dd566'
serial='23500027' firmware='1.0.4'/>
where the format of the firmware version is something I guessed at,
but it was the obvious choice (again, it's byte-based, I'm ignoring
the high byte that is zero for both of my Suuntos).

The legacy nickname wrappers (that use the device_info structure) are
left in gtk-gui.c. We can slowly start moving away from them, we don't
want to start exporting that thing as some kind of generic interface.
This isn't a pure code movement - because we leave the legacy interfaces
alone, there are a few new interfaces in device.c (like "create a new
device_info entry") that were embedded into the legacy "create nickname"
code, and needed to be abstracted out.
