While having the background "come down" seemed like a good visualization
of the ceiling, some divers appear to prefer something more dramatic. This
adds an option to the Tec Settings to have the ceiling shown in red
instead of the default background color.

Subject: [PATCH 2/2] Tune the dive joining surface event insert code
So this makes us do surface events only if the samples are more than one
minute apart, and are shallow enough (randomly selected at 5m).
We can add more heuristics. Maybe we should compare the 1-minute sample
time limit of the previous sample to the time to the sample before that:
if some computer (or manually entered dive) has a long time between
*all* samples, we'd make the cut-off time longer.
Baby steps.

This doesn't really change the logic of the merging, but it does mean
that the end result tends to be less unexpected: when downloading dives
that end up being merged with pre-existing dives (because you have
multiple dive computers, for example), the newly downloaded dive data
will tend to be appended to the old dive data, rather than showing up
first.

Loading these two XML files created a divelist with two trips that each
started at the same time but that were NOT linked together (because the
code in insert_trip detected that they started at the same time). Since
the trips were not linked together, trying to then merge those two trips
from the UI got us into an infinite loop, trying to move a dive from one
trip into the same trip (as the code couldn't find the trip that wasn't
linked into the dive_trip_list).

This actually makes us internally use 'micro-degrees' for latitude and
longitude, and we never turn them into floating point either at parse
time or save time.
That said, the Uemis downloader internally does still use atof() when
converting things, which is likely a bug (locale issues and all that),
but I'll ask Dirk to check it out.

I hate using floating point, this tries to at least make parts of it be
integer logic, and avoid the whole locale issue. This still keeps the
latitude and longitude internally as a floating point value, and parses
it that way, but I'm slowly moving towards less and less FP use.
We're going to use micro-degrees for location information: that's
sufficient to about a tenth of a meter precision, and it fits in a
32-bit integer.
If you specify dive sites with more precision than that, you may have

Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
We have been very careful not to mess with the numbering that a user may

dives appears to be the first time download from a dive computer. Right
now all dives show up with number '0' and that's just really ugly and a
bad experience for a first time user.
With this change if a user starts with an empty data file and downloads
dives from a computer for the first time, Subsurface will give them
numbers starting with '1'.

This patch does 4 small divelist.c changes in the following
order of importance:
1) In find_trip_by_time() now there is a check if a trip is actually found
before looking at the "when" flag.
2) Make remember_tree_state() slighly safer. If for example we have recently
deleted a trip from the linked list, it may still exist in the GTK tree model,
thus we want to check when calling find_trip_by_time() if there is an actual
match before setting the "expanded" flag for a trip.
3) When merging two trips in merge_trips_cb(), only use the tree model
to retrieve the timestamps (DIVE_DATE) and then find matching trips with
find_matching_trip(). Once we have pointers to the two trips to be merged,
move dives from one to another iterating with add_dive_to_trip().
4) In merge_trips_cb() - remember the tree state, repopulate the tree and
restore tree state, since now we are not adding/removing rows directly.

This tunes the heuristics for when to merge two dives together into a
single dive. We used to just look at the date, and say "if they're
within one minute of each other, try to merge". This looks at the
actual dive data, and tries to see just how much sense it makes to
merge the dive.
It also checks if the dives to be merged use different dive computers,
and if so relaxes the one minute to five, since most people aren't
quite as OCD as I am, and don't tend to set their dive computers quite
that exactly to the same time and date.
I'm sure people can come up with other heuristics, but this should
make that easier too.
NOTE! If you have things like wrong timezones etc, and the
divecomputer dates are thus off by hours rather than by a couple of
minutes, this will still not merge them. For that kind of situation,
we'd need some kind of manual merge option. Note that that is *not*
the same as the current "merge two adjacent dives" together, which
joins two separate dives into one *longer* dive with a surface
interval in between.
That kind of manual merge UI makes sense, but is independent of this
partical change.

This commit changes the code that was recently introduced to deal with
deco ceilings. Instead of handling these through events we now store the
ceiling (which in reality is the deepest deco stop with all known dive
computers) and the stop time at that ceiling in the samples.
This also adds support for NDL (non stop dive limit) which both dive
computers that appear to give us ceiling / deco information appear to
give us as well (when the diver isn't in deco).
If the mouse hovers over the profile we now add support for displaying the
NDL, the current deco obligation and (if we are able to tell from the
data) whether we are at a safety stop.

The downloader has been integrated into Subsurface for a while and with

Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
The initial downloader reused the XML parsing of SDA files that was
implemented early in order to support the information extracted from the
SDA with the java applet. But creating this intermediary XML file and
handing it off to the XML import function always seemed like an ugly way
to do things. This became even more obvious when adding more features to
the Uemis downloader.
This commit completely changes the downloader to instead create dives and
record them directly.
This also adds support for divespots (which are stored in a seperate
database that needs to be queried after the divelog and dive entries have
been combined - the Uemis firmware clearly was written by monkeys on
crack - oh wait: I'm trusting these same people to get the deco right?).
This commit leaves the SDA import capability in the XML parser intact.
I'll remove that later. Because of this it actually adds a few lines of
code, but the overall change will be a substantial code deletion.

Actually, it's even better than that. Thanks to the new divecomputer
datastructure we can now simply look up in the dive_table which dives have
been downloaded from this specific Uemis SDA.
This patch removes the old gconf based code - which leads to one
unfortunate problem: the first time a Uemis SDA owner runs this version of
Subsurface against their data file ALL dives will be downloaded again
(which may not be a bad thing as we have improved a few other details of
Uemis support so now they get their deco information, surface pressure and
other data that we have started to support since 2.1). Still, this is not
ideal. But I didn't want to keep the legacy code around since this new
solution is so much cleaner.

I was a little too eager to add the deco feature to Subsurface. Jef and I
went back and forth a few more times and the definition of those events
changed. I guess I shouldn't have commited that code until the
corresponding libdivecomputer code had been pushed.
This commit now brings us in sync with the current master of
libdivecomputer (but should compile with 0.2 as well - only deco events
won't work then).
One issue that I see is that deco / ndl aren't really a good fit for the
event model. I actually disabled the drawing of the little yellow
triangles for ndl events as for example on the Uemis those events are
created whenever the remaining non stop time changes - and that can be
every few seconds.
The correct solution may be to treat this as a function of the samples,
but for now this works and is tested with both OSTC and Uemis SDA.

This actually triggers for one of our insane test dives (test15): it has
no samples, so we created a fake dive computer entry with the a fake
profile in it, but we didn't copy the events over.
Having a dive with no samples, yet having events from the dive computer,
sounds pretty bogus. But that test-case did show that when that bogus
situation happens, we had two independent buglets: (a) we didn't insert
the entries in the fake dive computer entry we used and (b) we would
then mix up the events of the fake dive computer entry with the first
dive computer of a dive.
Fix this, just to make test15 happy again. And eventually, when we
actually plot the information for multiple dive computers, fixing case
(b) would become necessary even for real dives.

Both dives and dive trips have the same 'tripflag' thing, but they are
used very differently. In particular, for dive trips, the only case
that has any meaning is the TF_AUTOGEN case, so instead of having that
trip flag, replace it with a bitfield that says whether the trip was
auto-generated or not.
And make the one-bit bitfields explicitly unsigned. Signed bitfields
are almost always a mistake, and can be confusing.
Also remove a few now stale macros that are no longer needed now that we
don't do the GList thing for dive list handling, and our autogen logic

It simplifies the code a lot too, because it's much more natural to
