a71b7e51d2 libdivecomputer: small wording change in a warning
While in theory the DEVINFO event should give us the correct detected
product, it's also possible that the code that usually detects the
product gave up and returns an unknown model.

Try to have the message reflect that situation more accurately.

ff9506b21b Import: don't add to new trip while downloading
Since process_imported_dives() can add dives to a newly generated
trip, this need not be done in the downloading code. This makes
data flow distinctly simpler, as no trip table and no add-new-trip
flag has to be passed down to the libdivecomputer glue code.

Moreover, since now the trip creation is done at the import step
rather than the download step, the latest status of the "add to
new trip" checkbox will be considered.

11d19abc74 Dive download: add trip_table to device_data_t
Since recent commits, dive-trips are not added directly to the core,
but into separate trip tables (see ec37c71f5e).
These commits did not finish the work for the download-from-dc
case.

Add an extra trip_table field to device_data_t. If trips are created
(user selected "Download into new trip"), the trip will be created
in that table.

ec37c71f5e Core: add trip_table parameter to trip-functions
Currently trips are added to the global trip table. If we want to
make dive-import undoable, we should be able to parse trips of a
log-file into a distinct table. Therefore, add a trip_table
parameter to
	- insert_trip()
	- create_and_hookup_trip_from_dive()
	- autogroup_dives()
	- unregister_trip()
	- remove_dive_from_trip()

bfe69239df Import: unglobalize downloadTable
To make data flow more clear, unglobalize the downloadTable object.
Make it a subobject of DownloadThread. The difficult part was making
this compatible with QML, because somehow the pointer to the
download-table has to be passed to the DiveImportedModel. Desktop would
simply pass it to the constructor. But with objects generated in QML
this is not possible. Instead, pass the table in the repopulate()
function. This seems to make sense, but for this to work, we have to
declare pointer-to-dive-table as a Q_METATYPE. And this only works
if we use a typedef, because MOC removes the "struct" from "struct
dive_table". This leads to compilation errors, because dive_table is
the symbol-name of the global dive table! Sigh.

28e3413ff6 Add 'location_t' data structure
Instead of having people treat latitude and longitude as separate
things, just add a 'location_t' data structure that contains both.

Almost all cases want to always act on them together.

This is really just prep-work for adding a few more locations that we
track: I want to add a entry/exit location to each dive (independent of
the dive site) because of how the Garmin Descent gives us the

ebee0c4c24 Fix error handling for libdivecomputer import
The error handling was incorrect for the case where we successfully
opened the libdivecomputer iostream in divecomputer_device_open(), but
the dc_device_open() call failed.

When the dc_device_open() failed, we would (correctly) not do the
dc_device_close() but we would _also_ not do the dc_iostream_close() to
close the underlying file descriptor, which is wrong.

Normally this isn't all that noticeable, partly because the common case
is that dc_device_open() succeeds if you actually do have a dive
computer connected, but also because most of the time it just leaked a
file descriptor or something like that.

However, particularly for the POSIX serial device case, libdivecomputer
does a

	ioctl(device->fd, TIOCEXCL, NULL)

call to make serial opens exclusive.  This is what we want - but if we
then fail at closing the serial file descriptor, we won't be able to
retry the import at all because now the next open will fail with EBUSY.

So the error handling was incorrect, and while it doesn't usually matter
all that much, it can be quite noticeable particularly when you have
transient errors.

420aab9454 Cleanup: don't produce no-dives error message in libdivecomputer.c
If no dives were downloaded in do_libdivecomputer_import(), an
error message would be produced. To check for downloaded dives,
the function would access the global downloadTable instead of
the actual table the dives are imported to (at the moment the
same - but the interface allows for a different table).

Move the error-creation to the caller to avoid this situation.
An alternative option would be to check the actual table the
dives were supposed to be downloaded to. But from a program-logic
point of view "no dives" does not seem like an error condition.

d2b8088cd8 Actually create a UUID when creating a dive site during download
The existing code creates a deterministic ID (not exactly "unique") in order to
help us avoid merge conflicts in git-storage mode. But as a side effect, if we
re-download the same dive twice from a dive computer that supports GPS (right
now only the Garmin Descent Mk1) we are guaranteed to create the same dive site
uuid when we do this. So when we download a dive - whether we will actually
*use* that dive later or not - we will be filling in the dive site information
with the data we got from the dive computer.

... and in the process we will be overwriting any data that was filled in
manually. The name of the dive site, but also possibly even the GPS of the dive
site (maybe the user decided to edit that using the map, because while the
automatically downloaded GPS data was "correct", maybe the user wanted to
change it to be the actual under-water location using the satellite data,
rather than the place where you started the dive or where you surfaced).

In order to avoid this collision, this patch just makes the libdivecomputer
download not use the dive time, but "time of download" for the dive site time,
and thus effectively generate a new uuid for every download.

c60d2ec3e3 use libdivecomputer 'fingerprint' to avoid downloading extra data
This opportunistically uses a cache of 'fingerprints' for already
downloaded dives.

As we download data from a dive computer, we save the fingerprint and
dive ID of the most recent dive in a per-divecopmputer fingerprint cache
file.

The next time we download from that dive computer, we will load the
cache file for that dive computer if it exists, verify that we still
have the dive that is referenced in that cachefile, and if so use the
fingerprint to let libdivecomputer potentially stop downloading dives
early.

This doesn't much matter for most dive computers, but some (like the
Scubapro G2) are not able to download one dive at a time, and need the
fingerprint to avoid doing a full dump.  That is particularly noticeable
over bluetooth, where a full dump can be very slow.

NOTE! The fingerprint cache is a separate entity from the dive log
itself.  Unlike the dive log, it doesn't synchronize over the cloud, so
if you download using different clients (say, your phone and your
laptop), the fingerprint cache entries are per device.

So you may still end up downloading dives you already have, because the
fingerprint code basically only works to avoid duplicate downloads on
the same installation.

Also, note that we only have a cache of one single entry per dive
computer and downloader, so if you download dives and then don't save
the end result, the fingerprint will now point to a dive that you don't
actually have in your dive list.  As a result, next time you download,
the fingerprint won't match any existing dive, and we'll resort to the
old non-optimized behavior.

c4c57b287e Increase size of name_buffer to fit any integer
In libdivecomputer.c, name_buffer is formatted with calls like
 snprintf(name_buffer, 9, "%d cuft", rounded_size);
This works fine in the regular case, but it generates compiler
warnings, since theoretically the integer might produce up to
11 digits, leading to a truncation of the string.

Increasing the size of name_buffer to 17 chars silences these
warnings. This may seem like pointless warning-silencing.
Nevertheless, in the case of invalid data, it might make debugging
easier since, in the above case, the "cuft" is never truncated.
In total, it seems that this is a benign change with potential,
though in a very unlikely case, positive effects.

adb4b66a05 Try to sanely download multiple concurrent cylinder pressures
This tries to sanely handle the case of a dive computer reporting
multiple cylinder pressures concurrently.

NOTE! There are various "interesting" situations that this whole issue
brings up:

 - some dive computers may report more cylinder pressures than we have
   slots for.

   Currently we will drop such pressures on the floor if they come for
   the same sample, but if they end up being spread across multiple
   samples we will end up re-using the slots with different sensor
   indexes.

   That kind of slot re-use may or may not end up confusing other
   subsurface logic - for example, make things believe there was a
   cylidner change event.

 - some dive computers might send only one sample at a time, but switch
   *which* sample they send on a gas switch event.  If they also report
   the correct sensor number, we'll now start reporting that pressure in
   the second slot.

   This should all be fine, and is the RightThing(tm) to do, but is
   different from what we used to do when we only ever used a single
   slot.

 - When people actually use multiple sensors, our old save format will
   start to need fixing.  Right now our save format comes from the CCR
   model where the second sensor was always the Oxygen sensor.

   We save that pressure fine (except we save it as "o2pressure" - just
   an odd historical naming artifact), but we do *not* save the actual
   sensor index, because in our traditional format that was always
   implicit in the data ("it's the oxygen cylinder").

so while this code hopefully makes our libdivecomputer download do the
right thing, there *will* be further fallout from having multiple
cylinder pressure sensors.  We're not done yet.

1e38d9239a Start cleaning up sensor indexing for multiple sensors
This is a very timid start at making us actually use multiple sensors
without the magical special case for just CCR oxygen tracking.

It mainly does:

 - turn the "sample->sensor" index into an array of two indexes, to
   match the pressures themselves.

 - get rid of dive->{oxygen_cylinder_index,diluent_cylinder_index},
   since a CCR dive should now simply set the sample->sensor[] indices
   correctly instead.

 - in a couple of places, start actually looping over the sensors rather
   than special-case the O2 case (although often the small "loops" are
   just unrolled, since it's just two cases.

but in many cases we still end up only covering the zero sensor case,
because the CCR O2 sensor code coverage was fairly limited.

It's entirely possible (even likely) that this migth break some existing
case: it tries to be a fairly direct ("stupid") translation of the old
code, but unlike the preparatory patch this does actually does change
some semantics.

For example, right now the git loader code assumes that if the git save
data contains a o2pressure entry, it just hardcodes the O2 sensor index
to 1.

In fact, one issue is going to simply be that our file formats do not
have that multiple sensor format, but instead had very clearly encoded
things as being the CCR O2 pressure sensor.

But this is hopefully close to usable, and I will need feedback (and
maybe test cases) from people who have existing CCR dives with pressure
data.

11a0c0cc70 Unify sample pressure and o2pressure as pressure[2] array
We currently carry two pressures around for all the samples and plot
info, but the second pressure is reserved for CCR dives as the O2
cylinder pressure.

That's kind of annoying when we *could* use it for regular sidemount
dives as the secondary pressure.

So start prepping for that instead: don't make it "pressure" and
"o2pressure", make it just be an array of two pressure values.

NOTE! This is purely mindless prepwork.  It literally just does a
search-and-replace, keeping the exact same semantics, so "pressure[1]"
is still just O2 pressure.

But at some future date, we can now start using it for a second sensor
value for sidemount instead.
