8c18add46b Do libdivecomputer imports in a separate thread
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.

5804c2970e Support gps coordinates for the location info
Sadly, no way to show them yet.  But it would be nice to let people
enter them (and it would be doubly nice to have a dive computer that
does it at the surface), and then perhaps just do the "point browser at
google maps" thing.

Saving/parsing tested by hand-feeding the location of Enenui (Molokini
Crater) from google maps by hand into my divelog.

3a6652634b Rename the project 'subsurface'
I never really liked 'diveclog' as a name - it's not like the C part is
all that important.  And while I could try to just make up another slang
word for despicable person (in the tradition of naming all my projects
after myself), I just can't see it.

So let's just call it "subsurface".

efb1fa44b8 Print the end temperature of the dive
Currently we print the temperature every five minutes. Especially with
dive computers that keep rather frequent temperature samples that means
that we have one more interesting data point that we don't label: the
surface temperature at the end of the dive.

This patch adds some logic to try to print the last temperature sample
that was recorded before the dive ended - unless that same value has
already been printed (to avoid silly duplications on dive computers with
less frequent sampling)

518ec33ba3 First pass to parse uemis Zurich '.SDA' files
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.

ce86289eed Add the capability to print a dive profile
Ok, this is the ugliest f*&$ing printout I have ever seen in my life,
but think of it as a "the concept of printing works" commit, and you'll
be able to hold your lunch down and not gouge out your eyeballs with a
spoon.  Maybe.

I'm just doing the cairo display as-is for the printout, which is a
seriously bad idea.  I need to not try to do colors etc, and instead of
having white lines on a black background I just need to make thelines be
black on white paper.

But that would involve actually changing the current "plot()" routine,
which is against the point of the exercise right now.  This really is
just a demonstration of how to add printing capabilities.

c7b9387d4b Separate the notion of creating the cylinder widgets from showing them
Now we always create the MAX_CYLINDER sets of cylinder widgets.  But we
don't actually pack them into the frame - that's a separate phase.

Right now we still do the stupid "always just pack two cylinders" thing,
but the idea is that we can pack just as many as the dive needs on a
per-dive basis.

This just always shows two cylinders, which is obviously bogus, but it's
a good test-case for the multi-cylinder case.

I need to figure out how to dynamically show the right number of
cylinders, but that also involves the notion of adding a cylinder in
order to fill out information that didn't use to exist.

That's lower priority - now the infrastructure seems to be there.

So if it's reporting 100% O2, we just ignore it.  Sure, it could be

wrong.

d45db9fac7 libdivecomputer integration: add a progress bar
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.

6b0bb87f5b Further work on libdivecomputer integration
.. this now registers the dive parsing callback, and starts to parse the
data.  So I can see the last divetime on my Suunto Vyper Air now.

Still a lot more boilerplate stuff to go, though.  The libdivecomputer
interfaces really are pretty insane: why should the caller set up the
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.

But whatever.  I'm taking pieces from "examples/universal.c" as I go
along (it's under LGPL 2.1).  I want to do it in small chunks just to
feel that I understand what's going on, rather than just blindly copying

	cd libdivecomputer

	./configure

nothing actually *works* yet.

The Diving Log temperature reading is in Fahrenheit for the samples (for

temperature of 8 degF.

Just throw away those bogus freezing temperatures.  Sure, they can

0c4e1697db Be more careful about unit changes
When we change units, we need to flush any currently active dive
information in the old units, and then carefully reload it in the new
units.

Otherwise crazy stuff happens - like having current cylinder working
pressure values that are in PSI because that *used* to be the output
unit, but then interpreting those values as BAR, because we changed the
units.

Also, since we now properly import working pressure from Diving Log,
stop importing the (useless) cylinder description.  The Diving Log
cylinder descriptions are things like "Alu" or "Steel".  We're better
off just making up our own.

Finally, since Diving Log has cylinder size in metric, make sure that we
do the "match standard cylinder sizes" *after* we've done all the
cylinder size conversions to proper units.

d1b30212ff Add more static cylinder types - and pick them up from the dive log
This adds a few more predefined cylinder types to the static list, but
perhaps more importantly, if we try to show a cylinder description that
we haven't seen before, we automatically add that description to the
list as well.

This way, if people have their own cylinder types, our cylinder
management will automatically figure them out and make it easy to enter
them.

NOTE! It might be best to add the new cylinder description at dive log
load time, rather than at 'show' time.
