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.

Now that we have more complete dive computer information, we can use
that to match the dives we download, and stop with the hacky "Would we
merge this" check.
For XML files without the explicit dive computer information, go back to

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.

We used to avoid some extra allocations by just allocating the dive
samples as part of the 'struct dive' allocation itself, but that ends up
complicating things, and will make it impossible to have multiple
different sets of samples (for multiple dive computers).
So stop doing it. Just allocate the dive samples array separately.

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.
Oops.

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
response back), but then use shorter timeouts once we have started
receiving data.
This uses up fewer of the ANS files and allows us to get more dives
downloaded before the SDA has to be unplugged to reset communications,
yet at the same time it still improves the overall download time.

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.

If the surface interval between two dives is more than half an hour,
don't try to call it a single dive. Just the dive profile will be
looking ridiculous.
Things like tank refills etc could also be a good thing to check (again,
the dive profile would look ridiculous), but the cylinder pressure going
up a small amount is actually normal (ie cylinder warming up in warmer
water on the surface). So I don't know what the proper limit for that

When we calculate the interval for the tick-marks for the dive, we need
to limit 'i' to be within the size of the array. The code does that
with a "i < 8" check, but the fact is, we must never increment past the
last entry, which is 7 (the size of the array is 8, but the last valid
index is 7).
This only happens for unrealistically long dives. Which you can trigger
either by inputting insane values for a manually created dive, or by
merging two dives that are consecutive, but not close to each other
time-wise (eg on different days ;)

This extends on our current tooltip logic (which shows events when you
mouse over them) to show tooltips for the whole profile area.
If you mouse over an event, that is still shown in the tooltip, but
even in the absense of events, the tooltip will be active, and mousing
over the profile area will show the time, depth and pressure.
This can certainly be improved upon further, but even in this form it is
useful.

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.

This introduces the notion of merging two disjoint dives: you can select
two dives from the dive list, and if the selection is exactly two dives,
and they are adjacent (and share the same dive trip), we support the
notion of merging the dives into one dive.
The most common reason for this is an extended surface event, which made
the dive computer decide that the dive was ended, but maybe you were
just waiting for a buddy or a student at the surface, and you want to
stitch together two dives into one.
There are still details to be sorted out: my Suunto dive computers don't
actually do surface samples at the beginning or end of the dive, so when
you stitch two dives together, the profile ends up being this odd "a
couple of feet under water between the two parts of the dive" thing.
But that's an independent thing from the actual merging logic, and I'll
work on that separately.

This just re-organizes the dive merging code so that we expose a new
"merge_dives(a, b, offset)" function that merges two dives together into
one with the samples (and events) of 'b' at the specified offset after
'a'.
We'll want to use this if a dive computer has decided that the dive
ended (due to a pause at the surface), but we really want to just turn
the two computer dives into one long one with an extended surface swim.
