This tries to make our fingerprinting code work better, by avoiding
using the "deviceid" field that has always been unreliable because we've
calculated it multiple different ways, and even for the same version of
subsurface, it ends up changing in the middle (ie we calculate one value
initially, then re-calculate it when we have a proper serial number
string).
So instead, the fingerprinting code will look up and save the
fingerprint file using purely "stable" information that is available
early during the download:
- the device model name (which is a string with vendor and product name
separated by a space)
- the DC_EVENT_DEVINFO 32-bit 'serial' number (which is not necessarily
a real serial number at all, but hopefully at least a unique number
for the particular product)
but because the model name is not necessarily a good filename (think
slashes and other possibly invalid characters), we hash that model name
and use the resulting hex number in the fingerprint file name.
This way the fingerprint file is unambiguous at load and save time, and
depends purely on libdivecomputer data.
But because we also need to verify that we have the actual _dive_
associated with that fingerprint, we also need to save the final
deviceid and diveid when saving the fingerprint file, so that when we
load it again we can look up the dive and verify that we have it before
we use the fingerprint data.
To do that, the fingerprint file itself contains not just the
fingerprint data from libdivecomputer, but the last 8 bytes of the file
are the (subsurface) deviceid and the diveid of the dive that is
associated with the fingerprint.

In one weird case (suunto), the code in libdivecomputer.c
generates a device node directly instead of going the usual
way (setting the data in the dc-structure of the imported
dive). It is unclear to me whether that has to be that way,
as it depends on the chronological order of callbacks to
event_cb() and dive_cb().
Therefore add a device_table pointer to device_data_t
so that the downloader can add the device to this table. This
only adds the pointer, but does not yet use it in the
downloading code.

This was only set but never read. Therefore, remove it. Divecomputer

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

Some divecomputer backends (ok, right now really only the Aqualung i770R

This is part of the whole "let's support the notion of dive computers
being exported as USB storage devices" push.
With an older libdivecomputer, we'll just fall back on failing the
operation, but we still want to support the generic notion of
DC_TRANSPORT_USBSTORAGE since we have our own internal Uemis downloader.
That one won't ever get to the open phase, since it's caught earlier.

This removes some special-case code for Uemis, replacing it with simply
passing in the device transport information.
This makes device enumeration work for the Garmin Descent (if it is
listed by libdivecomputer as a USB storage device, that is).
I don't actually do any of the libdivecomputer parsing yet, and only
have a stub for the Garmin Descent, but now the directory selection
works with that stub. The actual download obviously does not.

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.

This converts our old custom IO model to the new model that

to make things build, with further work by me.
The FTDI code is temporarily disabled here, because it will need to be
integrated with the new way of opening devices.
The ble_serial code goes away entirely, since now libdivecomputer knows

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.

Instead of being "custom serial", it's a IO model that allows serial or
packet modes, independently of each other (ie you can have a bluetooth
device that does serial over BT rfcomm and packet-based communication
over BLE GATT with the same serial operations that describe both cases).

Having subsurface-core as a directory name really messes with

autocomplete conflict and also was inconsistent with the desktop-widget
name for the directory containing the "other" UI.
And while cleaning up the resulting change in the path name for include
files, I decided to clean up those even more to make them consistent
overall.
This could have been handled in more commits, but since this requires a
make clean before the build, it seemed more sensible to do it all in one.
