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).

This simplifies the vendor/product fields into just a single "model"
string for the dive computer, since we can't really validly ever use it
any other way anyway.
Also, add 'deviceid' and 'diveid' fields: they are just 32-bit hex
values that are unique for that particular dive computer model. For
libdivecomputer, they are basically the first word of the SHA1 of the
data that libdivecomputer gives us.
(Trying to expose it in some other way is insane - different dive
computers use different models for the ID, so don't try to do some kind
of serial number or something like that)
For the Uemis Zurich, which doesn't use the libdivecomputer import, we
currently only set the model name. The computer does have some kind of
device ID string, and we could/should just do the same "SHA1 over the
ID" to give it a unique ID, but the pseudo-xml parsing confuses me, so
I'll let Dirk fix that up.

The code pretended to support this for libdivecomputer based downloads,
but it had never been hooked up when the native Uemis downloader was
implemented. When I finally decided to close that feature gap I realized
that the original code was, shall we say, "aspirational" or "completely
bogus" and therefore never worked.
So instead of just hooking up the code for the Uemis downloader I instead
implemented this correctly for the first time for both libdivecomputer and
the native Uemis downloader.
In order not to have to mess with multithreaded Gtk development I simply
opted for a helper function that fires on a 100ms timeout and have it end
the dialog without a response. This way we can run the dialog while
waiting for the download to finish, still update the progress bar and
respond in a useful manner to the user clicking cancel.

This will hopefully not be something we need often, but if we improve
support for a divecomputer (either in libdivecomputer or in our native
Uemis code or even in the way we handle (and potentially discard) events),
then it is extremely useful to be able to say "re-download things
from the divecomputer and for things that were not edited in Subsurface,
don't try to merge the data (which gives BAD results if for example you
fixed a bug in the depth calculation in libdivecomputer) but instead
simply take the samples, the events and some of the other unedited data
straight from the download".
This commit implements just that - a "force download" checkbox in the
download dialog that makes us reimport all dives from the dive computer,
even the ones we already have, and an "always prefer downloaded dive"
checkbox that then tells Subsurface not to merge but simply to take the
data from the downloaded dive - without overwriting the things we have
already edited in Subsurface (like location, buddy, equipment, etc).
This, as a precaution, refuses to merge dives that don't have identical
start times. So if you have edited the date / time of a dive or if you
have previously merged your dive with a different dive computer (and
therefore modified samples and events) you are out of luck.

The include of libdivecomputer/utils.h breaks the compilation
of subsurface as it is no longer present in the latest version
of libdivecomputer.

For this you need to get the current libdivecomputer tree, reconfigure,
build and install it first. But this cleans up some of the silly error
handling too, and has just a single "dc_device_close()" call etc, rather
than duplicating that (and the new dc_context_free()).

Subsurface doesn't compile on OS X any more, because libdivecomputer
changed the way the header inclusion works: the include path from
pkg-config no longer includes the final "libdivecomputer" component, and
instead of doing
#include <header.h>
for libdivecomputer headers, we're now supposed to do
#include <libdivecomputer/header.h>
instead. Which is cleaner anyway.
The reason this only bit us on OS X is that I never trusted pkg-config
that much for non-system libraries on Linux (maybe it works, maybe it
doesn't, I've seen it go both ways), so on Linux we just used our own
version of the include path, and thus weren't affected by the
libdivecomputer config change.
Clean up the includes while at it - we no longer need (or want) the
device-specific header files, since we just use the generic functions.

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.

.. 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.

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.

As reported by Mauro Dreissig, the progress bar doesn't work and causes
a SIGSEGV due to a missing allocation. The code broke when Dirk
separated out the GUI from the core code, and I hadn't tried
divecomputer downloads since.

The following are UI toolkit specific:
gtk-gui.c - overall layout, main window of the UI
divelist.c - list of dives subsurface maintains
equipment.c - equipment / tank information for each dive
info.c - detailed dive info
print.c - printing
The rest is independent of the UI:
main.c i - program frame
dive.c i - creates and maintaines the internal dive list structure
libdivecomputer.c
uemis.c
parse-xml.c
save-xml.c - interface with dive computers and the XML files
profile.c - creates the data for the profile and draws it using cairo
This commit should contain NO functional changes, just moving code around
and a couple of minor abstractions.
