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.

This removes the tripflag name array, since it's not actually useful.
The only information we ever save in the XML file is whether a dive is
explicitly not supposed to ever be grouped with a trip ("NOTRIP"), and
everything else is implicit.
I'm going to simplify the trip flags further (possibly removing it
entirely - like I did for dive trips already), and don't like having to
maintain the tripflag_names[] array logic.

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
has been simplified.

This is a hack to convert time stored in decimal notation to proper
seconds. When using metric units the default way of JDiveLog to store
seconds is to have the amount of seconds after decimal point (1.20 is 1
minute 20 seconds). In some odd case it is reportedly possible that the
seconds are actually 100 based, thus we need to convert that to seconds
(1.33333 will become 1 minute 20 seconds).

This makes the dive trip auto-generation a separate pass from the
showing of the dive trips, which makes things much more understandable.
It simplifies the code a lot too, because it's much more natural to
generate the automatic trip data by walking the dives from oldest to
newest (while the tree model wants to walk the other way).
It gets rid of the most annoying part of using the gtk tree model for
dive trip management, but some still remains.

I'm trying to remove (or at least simplify) the gtk tree model usage for

We already kept a count of dives per trip in order to figure out when
there are no more dives left and the trip needs to be freed. Now we
explicitly keep track of the list of dives associated with the trip too,
which simplifies the "find the time of the trip" logic.
We may want to sort it in time, but for now this is mainly about trying
to keep track of the divetrip relationships explicitly. I want to move
away from the whole "use the gtk tree model to keep track of things"
approach.

Now that we have dive computer device ID fields etc, we can do a much
better job of merging the dive computer data.
The rule is
- if we actually merge two disjoint dives (ie extended surface interval
causing the dive computer to think the dive ended and turning two of
those dives into one), find the *matching* dive computer from the
other dive to combine with.
- if we are merging dives at the same time, discard old-style data with
no dive computer info (ie act like a re-download)
- if we have new-style dive computers with identifiers, take them all.
which seems to work fairly well.
There's more tweaking to be done, but I think this is getting to the
point where it largely works.

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.

Also, note that we do *not* do the "find_sample_offset()" any more when
we merge two dives that happen at the same time - since we just keep
both sets of dive computer data around.
But we keep the function to find the best offset around, because we may
well want to use it later when *showing* the dive, and trying to match
up the different sample data from the multiple dive computers associated
with the dive.
Because of that, this causes warnings about the now unused function.

This also knows how to save and restore multiple dive computers in the
XML data, but there's no way to actually *create* that kind of
information yet (nor do we display it). Tested by creating fake XML
files with multiple dive computers by hand so far.
The dive computer information right now contains (apart from the sample
and event data that we've always had):
- the vendor and product name of the dive computer
- the date of the dive according to the dive computer (so if you change
the dive date manually, the dive computer date stays around)
Note that if the dive computer date matches the dive date, we won't
bother saving the redundant information in the XML file.

When we have a preferred dive computer that overrides old information
when merging two dives, we just copy the dive computer data over.
However, we need to clear the source of the dive computer data so that
we then don't free the sample data when that old source of the newly
merged dive gets free'd.
This fixes a memory scribble (and likely SIGSEGV) for the "prefer
downloaded" case.

When this was first implemented the assumption was that a downloaded dive
that is to be merged with an existing dive would have the same time stamp.
But as Linus pointed out even back then, this does fail if a dive has been
merged with a download from a different dive computer before (think:
download from computer a, then download same dive from b, then improve
something in the parsing from computer a and try to redownload; the time
stamp could have changed).
This commit also fixes a silly omission in the merge_dives() function
(which ended up ALWAYS prefering the downloaded dive) and finally
implements the necessary changes to mark dives downloaded from a Uemis SDA
as well.

Prior to this commit, gtk often decided to collapse the trip with the
selected dive after the user imported or downloaded additional dives.
Since Subsurface tracks dives as being selected even after gtk collapses a
trip (which clears all selection state as far as gtk is concerned) this
could lead to the strange situation that the user could click on a new
dive to select it without unselecting the already selected dive - and
suddenly edit or delete did things that were entirely unwanted.
With this change we explicitly save and then restore the tree state around
import and download operations. This ensures that the same dive(s) stay
selected and trips stay expanded and therefore avoids the issues described
here.

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.

The divecomputer download code will stop at a matching dive (unless
you check the "Download all dives" option when downloading).
However, the matching dive is an *exact* match, which works well when
you have a single dive computer, but is a big pain when you have
multiple. What happens is that the date of the dive will be determined
by whatever dive computer you used first, and then downloading from
other dive computers will not match exactly, but will merge (if the
computers are within a minute of each other).
And that will continue to happen every time you try to download from
that other dive computer.
So use the same logic as for the automatic dive merging: consider
"within one minute" to be a matching dive. So don't download dives
that will be merged - unless the user asks for it.
We do want to have some way of saying "force download of all dives
from today" or something like that, I suspect. Because while I don't
want to re-download *every* dive, I might want to force-merge the last
<N> dives.

And again buffer_insert contained the blatant bug.
The code wasn't copying the trailing '\0' when extending the string, which
usually didn't end up blowing up the code (and therefore kept the bug
hidden until now) because of the way realloc reused memory - we just had
trailing garbage strings. But sometimes we weren't so lucky and the strlen
in a subsequent call of buffer_insert would run past the end of the
allocated buffer.

This may seem like an esoteric corner case, but it will actually happen
reliably when re-downloading dives from the Uemis SDA:
If the user selects "Force downloada of all dives" in the "Download from
divecomputer" dialog and if the SDA runs out of space and needs to be
unmounted and remounted, then for the 'Retry' the 'force' flag should be
cleared - or the user will once again start from the first dive which
almost certainly is not what they expect.

Start every step with much longer timeouts (until we get the first

The GPS parsing and saving was using sscanf and sprintf respecively, and
since it is using floating point values (boo!) that affects both of
them. In a C/US locale, we use a period for decimal values, while most
European locales use a comma.
We really should probably just fix things to use integer values (degrees
and nanodegrees?) but this is the simplest fix/workaround for the issue.
Probably nobody ever really noticed until I tested the Swedish locale
for grins, since we don't have a good way to actually set the GPS
coordinates yet. I've got a few dives with GPS information that I
entered manually.

Most of the dive computers I have access to don't do the whole surface
event thing at the beginning or the end of the dive, so when you merge
two consecutive dives, you got this odd merged dive where the diver
spent the time in between at a depth of 1.2m or so (whatever the dive
computer "I'm now under water" depth limit happens to be).
Don't do that. Add surface events at the end of the first dive to be
merged, and the beginning of the second one, so that the time in between
dives is properly marked as being at the surface.
The logic for "time in between dives" is a bit iffy - it's "more than 60
seconds with no samples". If somebody has dive computers with samples
more than 60 seconds apart, this will break and we may have to revisit
the logic. But dang, that's some seriously broken sample rate.

We generate the average temperature statistics by adding up the
(converted to user unites - not in millikelvin) temperatures and then
dividing by the number of dives we've added up over.
HOWEVER.
We did that summing of the temperatures into an integer variable, even
though the converted temperatures are floating point. So things got
rounded down to integers and the average temperature was just bogus
(although reasonably close).
We could do the summing of the temperatures in millikelvin and only
doing the conversion to the user at the very end. But the smaller patch
is to just change the accumulator to a double value.
