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.

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"

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

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

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.

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 did that summing of the temperatures into an integer variable, even

rounded down to integers and the average temperature was just bogus

We could do the summing of the temperatures in millikelvin and only

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.
