ec3a968df9 android/usb: pass in the UsbDevice when downloading
This finally allows us to download from not just the first device, but specifically
the device that the user picks.

Passing the object through a void pointer is not nice - but since this traverses
C code other solutions (like passing an index into the list) seemed even worse.

cb28158b9a Add timestamps to libdivecomputer.log
Since I learned while trying to implement this that getting sub-second
resolution time in portable C99 is hard (especially for someone who is
used to the comfort of std::chrono and Howard Hinnants date library) the
timer-implemetation from libdivecomputer is now copied to the subsurface
source.

7c9f46acd2 Core: remove MAX_CYLINDERS restriction
Instead of using fixed size arrays, use a new cylinder_table structure.
The code copies the weightsystem code, but is significantly more complex
because cylinders are such an integral part of the core.

Two functions to access the cylinders were added:
get_cylinder() and get_or_create_cylinder()
The former does a simple array access and supposes that the cylinder
exists. The latter is used by the parser(s) and if a cylinder with
the given id does not exist, cylinders up to that id are generated.

One point will make C programmers cringe: the cylinder structure is
passed by value. This is due to the way the table-macros work. A
refactoring of the table macros is planned. It has to be noted that
the size of a cylinder_t is 64 bytes, i.e. 8 long words on a 64-bit
architecture, so passing on the stack is probably not even significantly
slower than passing as reference.

36aab0fe95 Add 'download_error()' helper for libdivecomputer download error reporting
In the previous commit, we just continued downloading dives when
download errors happened, but that also makes problems a lot easier to
miss because now they are possibly just transient reports in the
progress bar that get overwritten by the next dive being downloaded.

So this turns a number of these errors from using 'dev_info()' to use a
new 'download_error()' reporting model, which then uses the generic
subsurface error reporting functionality that is sticky and can handle
multiple errors.

It also adds a few 'dev_info()' calls for actual informational messages
about the state of downloading, although the new ones will probably
mainly end up happening before the progress bar is actually shown.  But
it might improve on some of the progress messages.

958dce3326 Keep parsing dives even if one dive parse failed
Eric Charbonnier reported a problem downloading the dives from his
OSTC2, and Jef debugged the libdivecomputer log and says:

 "Your ostc has 75 dives, but subsurface downloaded only one, and then
  stopped the download. That's because that first dive appears to be
  corrupt and fails to parse:

    ERROR: Buffer overflow detected! [in /win/subsurface/libdivecomputer/src/hw_ostc_parser.c:981 (hw_ostc_parser_samples_foreach)]

  Subsurface (incorrectly) considers that a fatal error and stops the
  entire download. From a user point of view, it would be much better to
  ignore the problematic dive, and continue downloading the remaining"

Subsurface used to just stop downloading if there were parsing errors,
but Jef further says:

 "How parser errors are handled is up to the application. Aborting the
  download is probably the worst option here. If a dive fails to parse
  (because the dive data is corrupt, the parser contains a bug, etc),
  that does not necessary mean the remaining dives can't be downloaded"

so let's change the logic to just continue downloading, and hope other
dives work better.

We might want to do better error reporting, right now the errors tend to
just cause "dev_info()" reports, which just set the progress bar text.
So you'll see it in the progress bar as it happens, but it won't get
really ever noted as an error, and it's easy to miss.

But that error reporting is a separate issue, and this just does the
"continue to the next dive" part.

00944f7a02 Core: pass dive, cylinder-id to fill_default_cylinder
The fill_default_cylinder() function calculated the MOD based
on the currently displayed dive. This does not seem to make sense:
- When importing dives, why would we care about the altitude and
  salinity of the currently displayed dive, possibly from a different
  trip.
- The planner is supposed to be thread-safe and should not touch
  global variables.

Of course this means that the importing-functions have to fill
out altitude and salinity before creating the default cylinder,
but this is their problem. For a freshly created dive they will
get the default values, which still seems less random than the
values from the displayed dive.

not directly change the divelist. Therefore, they shouldn't

ff9506b21b Import: don't add to new trip while downloading

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

rather than the download step, the latest status of the "add to

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.

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.

Move the error-creation to the caller to avoid this situation.

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.

Also add another helper: "legacy_format_o2pressures()" which checks the

pressure sensor to use for that legacy format.

Because both the XML and the git save format will need a way to save the

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.

d01b7bf891 Switch over to SSRF_CUSTOM_IO v2
I hate changing the IO interfaces this often, but when I converted the
custom serial interface to the more generic custom IO interface, I
intentionally left the legacy serial operations alone, because I didn't
want to change something I didn't care about.

But it turns out that leaving them with the old calling convention
caused extra problems when converting the bluetooth serial code to have
the BLE GATT packet fall-back, which requires mixing two kinds of
operations.

Also, the packet_open() routine was passed a copy of the 'dc_context_t',
which makes it possible to update the 'dc_custom_io_t' field on the fly
at open time.  That makes a lot of chaining operations much simpler,
since now you can chain the 'custom_io_t' at open time and then
libdivecomputer will automatically call the new routines instead of the
old ones.

That dc_context_t availability gets rid of all the

	if (device && device->ops)
		return device->ops->serial_xyz(..);

hackery inside the rfcomm routines - now we can just at open time do a simple

	dc_context_set_custom_io(context, &ble_serial_ops);

to switch things over to the BLE version of the serial code instead.

Finally, SSRF_CUSTOM_IO v2 added an opaque "dc_user_device_t" pointer
argument to the custom_io descriptor, which gets filled in as the
custom_io is registered with the download context.  Note that unlike
most opaque pointers, this one is opaque to *libdivecomputer*, and the
type is supposed to be supplied by the user.

We define the "dc_user_device_t" as our old "struct device_data_t",
making it "struct user_device_t" instead.  That means that the IO
routines now get passed the device info showing what device they are
supposed to download for.

That, in turn, means that now our BLE GATT open code can take the device
type it opens for into account if it wants to.  And it will want to,
since the rules for Shearwater are different from the rules for Suunto,
for example.

NOTE! Because of the interface change with libdivecomputer, this will
need a flag-day again where libdivecomputer and subsurface are updated
together. It may not be the last time, either.

fe5f15bdc5 Add support for libdivecomputer using DC_SAMPLE_GASMIX
New libdivecomputer versions use DC_SAMPLE_GASMIX to indicate a gas
change (which contains the cylinder index we're changing to) rather than
SAMPLE_EVENT_GASCHANGE*.

Unlike the old GASCHANGE model, and despite the name, DC_SAMPLE_GASMIX
does not actually say what the mix is, it only specifies a cylinder
index.  We had already extended SAMPLE_EVENT_GASCHANGE2 to have the
cylinder index in the otherwise unused "flags" field, so this is not all
that different from what we used to do.

And subsurface internally already had the logic that "if we know what
the cylinder index is, take the gas mix from the cylinder data", so
we've already been able to transparently use _either_ the actual gas mix
or the cylinder index to show the event.

But we do want to make it an event rather than some sample data, because
we want to show it as such in the profile.  But because we are happy
with just the cylinder index, we'll just translate the DC_SAMPLE_GASMIX
thing to the SAMPLE_EVENT_GASCHANGE2 event, and nothing really changes
for subsurface.

libdivecomputer has made other changes, like indicating the initial
cylinder index with an early DC_SAMPLE_GASMIX report, but we've seen
that before too (in the form of early SAMPLE_EVENT_GASCHANGE events), so
that doesn't really end up changing anything for us either.

HOWEVER, one thing that is worth noticing: do *not* apply this patch and
then use an old libdivecomputer library that sends both the
DC_SAMPLE_GASMIX samples _and_ the deprecated SAMPLE_EVENT_GASCHANGE
events.  It will all *work*, but since subsurface will take either,
you'll then get duplicate gas mix events.

It's not like that is in any way fatal, but it might be a bit confusing.

983561b353 ostctools_import: Switch to using dc_parser_new2
Instead of creating the individual parsers, and keeping track of their
arguments, this just uses the "new" dc_parser_new2 function ment for
buffer parsing.

70e2404492 Stop accessing the internals of dc_descriptor_t
This removes our own declaration of dc_descriptor_t and all our accesses
to its internals, and switches to use the libdivecomputer functions to
access those instead.
