Some divecomputer backends (ok, right now really only the Aqualung i770R
and i300C) want to know the bluetooth name of the dive computer they
connect to, because the name contains identifying information like the
serial number.
This just adds the support for that to our Qt BLE code.

process_imported_dives() is more efficient for downloaded than for

Dive importing is now performed via a distinct table which is
merged into the main dive table. Thus, it is known which of the
dive is new and which is old. This information can now be
implicitely encoded in the parameter-position of merge_dive()
[i.e. pass old as first and new as second dive].
This makes marking of downloaded dives via a flag unnecessary.

Dives were directly imported into the global dive table and then
merged in process_imported_dives(). Make this interface more flexible,
by passing an independent dive table.
The dive table of the to-be-imported dives will be sorted and merged.
Then each dive is inserted in a one-by-one manner to into the global
dive table.
This actually introduces (at least) two functional changes:
1) If a new dive spans two old dives, it will only be merged to the
first dive. But this seems like a pathological case, which is of
dubious value anyway.
2) Dives unrelated to the import will not be merged. The old code
would happily merge dives that were not even close to the
newly imported dives. A surprising behavior.

The old surface interval calculation had fundamental issues:
1) process_all_dives(), which calculates the statistics over *all*
dives was used to get the pointer to the previous dive.
2) If two dives in the table had the same time, one of those would
have been considered the "previous" dive.
3) If the dive, for which the surface interval is calculated is
not yet in the table, no previous dive would be determined.
Fix all this by creating a get_surface_interval() function and
removing the "get previous dive" functionality of process_all_dives().
Remove the process_all_dives() call from TabDiveInformation::updateData().

Because some BLE operations can be very slow (device and service
discovery etc), we have some rather excessive default timeout for BLE
(currently set to 12 seconds).
But once we actually have started doing IO, that long timeout can be a
big performance problem, when the libdivecomputer backend has support
for retry and packet loss.
For that reason, libdivecomputer has a 'set_timeout()' function that
allows the divecomputer backend to say how quickly it expects the dive
computer to answer before the backend will start resending packets.
Let's just implement that for the actual IO side of BLE too. The
default timeout value remains the general BLE timeout, and this only
affects the actual IO phase, but it improves things enormously for the
case where there is packet loss at that point.
For example, on the Aqualung i770R, the timeout for packet loss ends up
now being just one second rather than the full 12 seconds of default BLE
timeout. Which gets the retry going much faster.

In commit 30fb7bf35c ("qt-ble: set up infrastructure for better
preferred service choice") I moved the service filtering from the
addService() callback into the "select_preferred_service()" function
that picks the right service for the device.
That was nice for debugging, since it meant that we showed the details
of _all_ services, but it also meant that we ended up starting service
discovery on _all_ services, whether they looked at all interesting or
not.
And that can make the BLE device discovery process quite a bit slower.
The debugging advantage is real, but honestly, service discovery can
generally be better done with specialized tools like the Nordic nRF app,
so the debugging advantage of just listing all the details of all the
services is not really worth the discovery slowdown in general.
So move the basic "filter by uuid" back to the service discovery phase,
and don't bother starting service detail discovery for the services that
we can dismiss immediately just based on the service UUID.

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.

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.

The Uemis downloader determines the dive-number to be downloaded
by either checking the download-table [interrupted connection] or
the global dive table [fresh download].
The downloadTable is passed in the device data structure, but
in the function to determine the latest dive, the global
downloadTable is accessed directly [thus supposing that this
table was passed in device data].
Instead, use the table from device data to avoid funny surprises

Currently, we can only delete dives that are indexed in the main

The existing BLE dive computers treat BLE as the packetized protocol it
is, and read whole packets at a time.
However, the Mares BlueLink backend treats it as just a basic "serial
over BLE" transport, and for historical reasons reads the reply packets
in smaller chunks.
This allows that kind of IO behavior, where if the divecomputer backend
reads just a part of a packet, we'll split the packet, return the part
the user asked for, and push back the leftover packet onto the received
packet queue.

XMP is a media-metadata standard based on XML which may be used
across a variety of media formats. Some video-processing software
writes XMP data without updating the native metadata fields.
Therefore, we should aim at reading XMP metadata and give priority
of XMP data over native fields.
Pros:
- Support for *all* common media formats.
Cons:
- XML (complex, verbose, chaotic).
- Does not even come close to fulfilling its promise of being
well defined (see below).
Implement a simple XMP-parser using libxml2. Connect the XMP-parser to
the existing Quicktime/MP4 parser.
First problem encountered: According to the spec, XMP data supposed
to be put in the 'XMP_' atom. But for example exiftools instead
writes an 'uuid' atom with a special 16-byte uid. Implement both,
more options will probably follow.
Second problem: two versions of recording the creation date were found
1) The content of a <exif:DateTimeOriginal> tag.
2) The xmp::CreateDate attribute of a <rdf:Description> tag.
Here too, more versions are expected to surface and will have
to be supported in due course (with an obvious priority problem).

We used to just blindly pick "first" and "last" characteristic from the

So re-organize the code to actually look at the properties of the
characteristics. I don't have a BlueLink to test with, but my EON Core

We used to just pick the first non-standard service we found (with a
special case for the Heinrichs Weikamp dive computers that have an
actual registered standard service).
We then waited for that service to finish discovery, and started using
it.
This changes the logic to wait for _all_ services to finish discovery,
and then after that we pick the one we like best. Right now the rule
for picking a preferred service is the same one we had before, but the
difference is that we now have the full discovery data, so we *could* do
something better.
Plus this makes our debug messages a lot more legible, when we don't
have the mix of overlapping service discovery with the actual IO we do
to the preferred service.
NOTE! This doesn't much matter for most of the dive computers that we
currently support BLE for. They don't tend to have a lot of odd
services.
But at least both the Mares BlueLink and the Garmin Descent both have
multiple services and it's not obvious which one to use, and this will
make it not only easier to debug those, it will make it easier to pick
the right preferred service descriptor to use.

process_dives() is used to post-process the dive table after loading
or importing. The first parameter states whether this was after
load or import.
Especially in the light of undo, load and import are fundamentally
different things. Notably, that latter should be undo-able, whereas
the former is not. Therefore, as a first step to make import undo-able,
split the function in two versions and remove the first parameter.
It turns out the the load-version is very light. It only sets the

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.

On import of dive media, the timestamp is read from the

The pictures are then listed in a dialog.

out that the picture is not valid again in picture_get_time()
to display the proper timestamp.
Even though metadata-extraction is reasonably fast, this is
a bit of an embarrassment.
Instead, read the timestamps only once in the constructor of
