This does mean that you have to build subsurface against a new version
of libdivecomputer, and that version is likely going to have various
slightly incompatible changes. But the new interfaces allow for easily
adding new supported dive computers without subsurface having to be
updated for each new vendor and model, so some slight pain is definitely
worth it this time.
I'm not even going to try to have some backwards-compatible version
here, the libdivecomputer interface changes are so extensive. Native
enumeration of devices is just the smallest part of it: the constants
and types that libdivecomputer uses now have much nicer names that all
start with DC_ or dc_, so you don't get the kinds of name clashes we had
with "gasmix_t" etc.

I'm hoping most other dive computers are quicker to import from than the
Suunto I have, but mine can take minutes to import all the dives. Sure,
we have that nice progress bar, so it shows that it's doing something,
but it's not really showing *what* it is doing.
So instead of showing just "Parsing dive X", let's show the date of the
dive. That way, when it takes two minutes to import all the dives, at
least you can see "oh, it's going back to the dives of last year" and it
then feels like you have some good reason for the delay.

Instead of using printf() to print the string updates ("Parsing sample
data" etc), introduce a function to show those strings in the graphical
progress bar itself.
Subsurface hasn't been a text-mode application in a long time ;)
This partially fixes the second todo entry from commit b0ba22a068
("Show dive import error messages in the import dialog") and generally
makes for a more helpful import - at least for the largely error-free
cases.
Sadly, the messages that really come from within libdivecomputer itself
(like "suunto_vyper2.c:193: Failed to receive the answer.") when things
go really wrong are not caught. libdivecomputer does have a notion of a
logfile (set with "message_set_logfile()"), but that ends up being
really inconvenient.
Maybe we could use some pipe setup or something. Oh well.

.. not in the main window. And leave the import dialog open, so that
you can either try doing it again, or cancel. This makes it much easier
to re-try a failed dive import, and actually makes the failure more
obvious too.
Todo:
- make the "Ok" button change to "Retry" when an error happens
- try to see if we can catch the actual status update messages from
libdivecomputer and show them too in the import dialog. Right now
they are printed out to stderr by the library.

libdivecomputer has the absolute worst interfaces to any library *ever*,
and randomly changes those crappy interfaces when it adds support for
new dive computers.
It would have been much better if the interface was just a "open this
device" with a device descriptor structure pointer, so that when Jef
adds support for new devices, the old descriptors still stay around and
work the same way - there's just a new descriptor structure that you
*can* use if you want. Along with a data structure to name the devices
and their descriptors, this would actually mean that users could just
support pretty much any random device that LD supports.
But no, that's not how libdivecomputer works. It has random enums and
crazy different ad-hoc interfaces for different dive computers. Or,
like in this case, crazy different ad-hoc interfaces for the *same*old*
dive computer.
Right now, for example, the support for the new Heinrichs Weikamp "Frog"
computer added a flag to the interface for the old OSTC_2 support.
Breaking any libdivecomputer users even if you didn't need Frog support.
And is there a version number in the header files to check for? Yes,
there's a version number. But no, it's not useful, since it doesn't
actually change with the interface changes. This time, Jef actually did
change the version number (from 0.1.0 to 0.2.0) as part of new
development version, but there's no reason to believe that it will
change in the future as the interfaces change - it never has before.
So it's actually safer - and easier to understand - to check for the
existence of the new header file inclusion mechanism. A new version of
libdivecomputer that supports the HW Frog computer will include the
"ostc_frog.h" header file when you include the libdivecomputer device.h
file, and that will result in HW_FROG_H being defined.
So we can check whether libdivecomputer has the new interface and
supports the Frog by doing an "#ifdef HW_FROG_H" hack. Ugh.

Remove casts from/to void*. They are unneeded in C, can hide problems
in the future, and are far too C++ish. Furthermore, they were
inconsistent with the rest of the code and even with regards to
themselves (at least in terms of whether or not to have space after the
cast).
In this case, we temporarily lose const specifiers in libdivecomputer.c
due to the unneeded cast, so it seems better to avoid the cast at all,
so you get warned about a const->non-const cast if you ever change it to
do something like this.
The casts in gtk-gui.c are just useless semantically, although they
might be useful as a hint to the reader that the void pointers are char
arrays.

When importing (or reading xml from files) new dives, we now renumber
them based on preexisting dive data, *if* such re-numbering is obvious.
NOTE! In order to be "obvious", there can be no overlap between old and
new dives: all the new dives have to come at the end. That's what
happens with a normal libdivecomputer import, since we cut the import
short when we find a preexisting dive.
But if any of the new dives overlap the old dives in any way, or already
have been numbered separately, the automatic renumbering is not done,
and you need to do a manual renumber.

We can instead 'Open' these files as they are just bastardized XML files.
This gets us back to a more consistent point where 'Import' gets data
directly from the dive computer (and hopefully soon we will add the
ability to load a dive directly from a uemis SDA to libdivecomputer),
and 'Open' loads a file from the filesystem of the computer we are
running on (this last sentence phrased so awkwardly as the uemis Zurich
SDA is a computer and presents a file system when connected via USB - it
just doesn't have the dive data in an accessible format in that file
system).
As a bonus we get to throw away quite a bit of code (the uemis specific
file handling, mini-XML parser with helper functions, the file open dialog
in the importer). Yay!

The libdivecomputer interfaces are pure crap. There are no generic
"open the dive computer" or "create a parser for the dive computer"
interfaces, instead each dive computer you support has its own open and
parser generator interface.
And they change. Happily fairly seldom, but they change. And two days
ago, Jef changed the interface for the Mares Icon HD computer in order
to support the newer HD Net Ready variant.
I've asked Jef to make a sane interface for "open the dive computer" and
"just create the parser" for libdivecomputer, but he claims that he
cannot just track the device model details internally. Which is
obviously a completely bogus claim, since the way *we* track the model
details is to just feed it back from the silly event.
libdivecomputer should just do that internally and not bother us with
its crazy internal model numbers. But whatever.
In the meantime, work around this braindamage, and hope that
libdivecomputer comes to its senses some day.

I don't know about other dive computers, but the Suunto Vyper Air is
slow as hell to import all the dives from. And libdivecomputer seems to
be importing dives "most recent first", so this just makes it stop
importing dives when it finds a dive that we've already seen.
Caveat: libdivecomputer has this fancy notion of "dive fingerprints",
and claims that's the way to do things. That seems to be overly
complicated, and not worth the bother.
If you worry about the import finishing early due to already having some
dives with the same date in your dive list, just import starting from an
empty state, and thus get a pure "dive computer only" state with no
early out. Then you can just load the old dives afterwards, and depend
on subsurface merging any duplicates.
But for normal operation, when you just want to import a couple of new
dives from your dive computer, the "exit import early when you see a
duplicate" is the right thing to do.

This is the hackiest thing ever, unless you count the previous code that
was even hackier (and just called the gtk main routine at random
places).
The libdivecomputer library is not really set up to be part of the gtk
main loop, and cannot afford (for example) to have lots of mainloop
events while it's parsing. Some dive computers are very timing
sensitive for the communication.
So just start a thread for doing the libdivecomputer stuff, and just
continually call the gtk main loop while that thread is running. I'm
sure we could actually use some gtk signalling thing to make the thread
exit do the right thing, but instead we just poll the status every
100ms.
I did say it was hacky. It does seem to work, though. No more
temporary graying out of the windows when they don't react in a timely
manner because libdivecomputer does some blocking operation.

This is missing a ton of the information in the .SDA files It only
parses the divelog.SDA file, not the dive.SDA file It ignores the
information on the gas(es) used and all the data on the tanks.
It still draws some strange artefacts at the end of the dive
But it correctly hooks into the import dialogue, it gives you a file
select box (somewhere, I'm sure, a gtk developer cries quietly) and then
parses enough of this file to serve as a proof of concept.

Instead of writing out the progress events, use them to update a real
progress bar.
Also, we need to handle gtk events while busy with the dive computer
reading. That should *probably* be done with a threading model, because
libdivecomputer does seem to have some timing sensitivity - I'm getting
"failure to read memory block" if I make that loop do the standard
while (gtk_events_pending())
gtk_main_iteration();
thing. Besides, even if we did do that loop, it would still cause
problems when the libdivecomputer code is stuck reading a serial line
that doesn't respond or whatever.
But for now this ugly hack is "good enough" to get further.

dive parsing for each computer type, when libdivecomputer knows what
types it has? IOW, much of that boilerplate should be hidden inside of
libdivecomputer, rather than exposed to the user.
