4e7161efd6 Do some basic sanity testing on the libdivecomputer gasmix data
It's quite often obvious crap for the "doesn't exist" or "plain air" case.

So if it's reporting 100% O2, we just ignore it.  Sure, it could be
right, but for the dives I have I know it's just libdivecomputer being
wrong.

Same goes for obvious crap like 255% Helium.

42f627b8b1 Libdivecomputer: start actually importing the dive data
So this actually reports the dive data that libdivecomputer generates.
It doesn't import special events etc, but neither do we for the xml
importer.

It is also slow as heck, since it doesn't try to do the "hey, I already
have this dive" logic and always imports everything, but the basics are
definitely there.

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.

d5b7f7dc06 Libdivecomputer integration, part n+1
This actually gets me far enough that it prints out all the dives on my
dive computer.  It doesn't actually turn them into real dives yet,
though - only a series of ugly 'printf's so far.

And it hangs after printing the last dive. So I'm doing something wrong.

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
it all.

9cb60c9106 Start some very initial libdivecomputer integration
Ok, so this is quite broken right now: it doesn't actually really *do*
anything, and it now requires that you have libdivecomputer all set up
and installed.

That is fairly easy:

	mkdir ../src
	cd ../src
	git clone git://libdivecomputer.git.sourceforge.net/gitroot/libdivecomputer/libdivecomputer
	cd libdivecomputer
	autoreconf --install
	./configure
	make
	sudo make install

but you may feel that this is not exactly useful considering that
nothing actually *works* yet.

Some day.

0282d515db Work around more Diving Log bugs..
The Diving Log temperature reading is in Fahrenheit for the samples (for
the per-dive water/air temperature it's in Celsius).  But it seems to
have a bug where a lack of a sample has been turned into 32 Fahrenheit
(which is 0 celsius).  This is despite the dive itself having a water
temperature of 8 degF.

Just throw away those bogus freezing temperatures.  Sure, they can
happen, and ice divers are crazy - but in this case I know it's just an
error in the log, and it looks very much like a Diving Log bug.

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.

61d0aa10e1 Parse 'Diving Log' cylinder working pressure
Oh Gods. Why are all other scuba programs so f*&% messed up?

The Diving Log cylinder working pressure is in bar - which is all good.
But their pressure *samples* are in PSI.  Why the h*ll do people mix up
units in the same damn file like that? I despair at the pure
incompetence sometimes.

I suspect the pressure samples aren't "really" in PSI: they are probably
in some user-specified 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.

1fe687a16c Add new cylinder models to the cylinder model store
We also need to actually fill the model store with the cylinder models
we have in our dive lists to begin with.

This makes it all *trivial* to add a new cylinder model: just use a new
description, fill in the size and working pressure, and you're done.
The type automatically gets filled in, unless that description already
existed (in which case we leave it alone).

c43e1ad21b Let people manage their cylinders in cuft and psi
If the output units are set to cuft and psi, then we should show the
cylinder size and pressure properly.

NOTE! In the absense of pressure data, we *always* show the cylinder
volume in liter.  There's no way to convert it to imperial units, since
the imperial units are not in physical size, but in air volume
normalized to surface pressure..

b17c7f0709 Now that we don't mess up import, we can save the cylinder working pressure
We used to have the heuristic that if we saw a cylinder working
pressure, then the cylinder size would be in cuft.  Which meant that we
couldn't export our working pressures, because it would mess things up
on import.

But working pressure is actually nice to know, if you ever work with
cylinders in imperial units.  So now that the import is fixed, add the
working pressure to the export.
