This ends up being just a file interface for dive computers that expose
their data as a filesystem that can be mounted.
Right now that's only the Garmin Descent Mk1, although technically the
Uemis Zurich also did that (but oddly, and the backend was never merged
into libdivecomputer).

The Uwatec Smart, Meridian and G2 backends are almost identical, except
for the low-level packet sending and receiving code. With the new I/O
layer, those three backends can easily be unified in a single backend.
The Meridian and G2 are completely removed, only the family types are
kept for backwards compatibility.
Several dive computers support multiple transports. For example the
Suunto Eon Steel supports both USB HID and BLE. All devices using
bluetooth classic communication support both the native bluetooth
transport and the legacy serial port emulation.
To support this feature, the values of the dc_transport_t type are
changed into bitmasks, and the dc_descriptor_t struct is extended with a
bitfield with all the supported transports.
Add a function to query the underlying transport type. This allows the
dive computer backends to implement transport specific behaviour where
necessary.
For the built-in I/O implementations, the transport type is obviously
always hardcoded, but for a custom I/O implementation the application
needs to provide the correct type. Hence the transport type can't be
hardcoded in the vtable and needs to be passed as a parameter.
The back-end parser seems to be the same as for the Uwatec Smart (aka
Galileo Sol). At least that's the assumption right now.
The downloader just uses USB HID (very similar to EON Steel) rather than
the horrible IrDA thing.
There's also eventually a BLE thing, but that's for the future.
This is an unholy mixture of the Uwatec Smart downloader logic and the
EON Steel usbhid transfer code. The back-end is pure Uwatec Smart
(model 0x11, same as Galileo Sol).
I'm not at all sure this gets everything right, but it downloads
*something*.
[Jef Driesen: Renamed the backend to uwatec, and made some smaller
cosmetic changes to match the existing coding style.]

Basic Suunto EON Steel downloading copied from my test application.
This parses all the core dive data, including sample data (time, depth,
cylinder pressure, deco information etc).
The deco information returns ceiling and TTS rather than ceiling and
"time at ceiling", because that's what the dive computer has, and I
don't see any other way to return the information.
We don't report any events yet, though.

The Uwatec Meridian protocol is identical to the Uwatec Smart/Galileo
protocol, except for some additional framing around each data packet,
and the switch from IrDA to usb-serial communication. For parsing, the
data format appears to be identical to the Galileo data format.
Although the communication protocol of the OSTC3 is nearly identical to
that of the Frog, the different size parameters make it hard to share
the code easily. On top of that, if we ever implement native bluetooth
communication support, we'll need a completely separate backend anyway.
Therefore the Frog backend is simply duplicated, with a few OSTC3
specific changes applied here and there.
The existing ostc parser is upgraded to support the new OSTC3 data
format.
The Petrel (with updated firmware) supports an enhanced communication
protocol, which is more efficient and powerfull than the legacy Predator
compatibility mode. The new protocol uses data compression for faster
transfers and supports the ability to selectively download individual
dives. Last but not least, the new protocol isn't limited to the last
128kB of logbook data, but can access the full logbook capacity (16MB).
This is only a preliminary version. There is certainly some room for
improvement, but the basic functionality is already in place. That
should be sufficient for daily use, and possibles issues can always be
fixed when discovered.
