The Sporasub SP2 uses a very simple communication protocol and memory
layout, but with some unusual aspects:
Dives are artifically limited to a maximum of 6000 samples.
Unlike all other dive computers, the dives are not stored in some kind
of ringbuffer structure. Once the memory is full, no new dives can be
recorded. The existing dives need to be erased first, and the dive
computer will start recording again at te start of the memory area. The
Sporasub application has an "Auto-clear watch memory after data
transfer" feature for this purpose.
I didn't implement a more efficient download algorithm because
downloading a full memory dumps takes less than 10 seconds.

Comparing signed and unsigned integer expressions can have unexpected
results because the signed integer will get promoted to an unsigned
integer. To avoid the warning, add an explicit cast to the unsigned
type, along with a check to catch negative values.
String literals have the type 'char[N]' by default. Allthough they are
not really 'const', modifying a string literal is undefined behaviour.
Therefore, to avoid mistakes, libdivecomputer uses the -Wwrite-strings
compiler option to change the default type to 'const char[N]'.
The cast that triggers the -Wcast-qual warning can be avoided by using a
character array instead of string literal.

Add initial support for the Oceans S1.
This expands a bit on the generic functions for the field-cache code,
and uses that to then add a fairly minimal Oceans S1 downloader.
And while it's minimal, it downloads about everything the S1 offers,
which is mainly just depth and temperature.
There are a few fields that it currently doesn't use, notably the
events and NDL information that the dive computer presumably reports in
the auxiliary data that comes in the sample, but without documentation
and more testing I'm not comfortable parsing that.
There's also some "current dive computer state" that isn't imported,
like the battery status. I know how to read it, but it's not per-dive
data that could be added as extra fields: it's literally just the
current dive computer battery state at the time of the download.
The Oceans team said they'll provide more information about the
download, so this might be expanded in the future, but it seems fairly
usable even in this form.
Thanks to Dhaval Giani for sending me his Oceans S1 as a loaner, and to
Seth Garrison for doing the initial BLE packet dumps that made me think
it was fairly easily doable.

This uses pretty much all of our new infrastructure: the USB storage
iostream for the actual IO, the field-cache for the divecomputer fields,
and the string interface for the events.
It's also a very fast downloader.

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).

This adds the infrastructure for the "field cache", which is just
various helpers for the dc_get_field() interface.
This includes the 'dc_field_cache_t' structure that a libdivecomputer
backend can just add to its parser data structure, and a few macros to
make it very easy to initialize the fields and then return them in the
'get_field()' callback.
And part of it is the infrastructure support for the 'dc_field_string_t'
type, which adds the support for string fields. That will be used to
return various string-formatted data from the dive computer, like deco
models, serial numbers, etc.
And no, a serial number is most definitely not a "number". It's a string.
Right now there are no users of this yet, that comes next.

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.
When two or more identical (or very similar) dive computers are
connected, the USB VID/PID can be ambiguous. That's because the VID/PID
identifies the type of the USB device, and not the individual device.
But each USB HID device descriptor returned by the device discovery
represents a single connected device, and thus guarantees to open the
correct USB device.
To obtain the same behaviour as before, an application can simply open
the first discovered device.
Setting a default transport type avoids the need to explicitely set a
transport using the the new --transport command-line option. This also
preserves backwards compatibility with previous versions where the
option didn't exist yet.
The dctool example application is updated to the latest changes:
- The I/O stream is opened and closed by the application.
- A new (mandatory) option is added to select the desired transport
type. This is nessecary because several dive computers support
multiple transport types now.
Currently the dive computer backends are responsible for opening (and
closing) the underlying I/O stream internally. The consequence is that
each backend is hardwired to a specific transport type (e.g. serial,
irda or usbhid). In order to remove this dependency and support more
than one transport type in the same backend, the opening (and closing)
of the I/O stream is moved to the application.
The dc_device_open() function is modified to accept a pointer to the I/O
stream, instead of a string with the device node (which only makes sense
for serial communication). The dive computer backends only depend on the
common I/O interface.
The device descriptor is either mandatory for a certain command (with
DCTOOL_CONFIG_DESCRIPTOR) or always NULL. But for some commands it will
be useful to support an optional descriptor as well. To support this, we
always try to lookup the device descriptor whenever the corresponding
command-line options are set.
Add a new type to distinguish between closed circuit (CCR) and
semi-closed circuit (SCR) diving. Some dive computers from HW and
DiveSystem/Ratio support this.
Because the CCR/SCR abbreviations are more commonly used, let's take the
opportunity to also rename the existing DC_DIVEMODE_CC. To preserve
backwards compatibility, a macro is added to map the old name to the new
one.

Allthough most dive computers always use local time and don't support
timezones at all, there are a few exceptions. There are two different
sources of timezone information:
- Some of the newer Uwatec/Scubapro devices use UTC internally and also
support a timezone setting. This UTC offset is currently taken into
account to obtain the dive date/time, but the UTC offset itself is
lost.
- Uwatec/Scubapro and Reefnet devices rely on the clock of the host
system to synchronize the internal device clock and calculate the
dive date/time. The consequence is that the resulting date/time is
always in the timezone of the host system.
In order to preserve this timezone information, the dc_datetime_t
structure is extended with a new "timezone" field, containing the UTC
offset in seconds. Devices without timezone support will set the field
to the special value DC_TIMEZONE_NONE.
The dc_datetime_localtime() and dc_datetime_gmtime() functions will
automatically populate the new field with respectively the local
timezone offset and zero. The dc_datetime_mktime() function will take
into account the new timezone field for the conversion to UTC. The
special value DC_TIMEZONE_NONE is interpreted as zero.
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*.

cosmetic changes to match the existing coding style.]

For applications supporting offline parsing (like libdivecomputer's own
dctool application), some device specific knowledge is still required in
order to map a particular model to the corresponding backend. The new
convenience function will take care of that internally.
The already existing dc_parser_new() function does the same, but
requires an open device handle, which makes it unsuitable for offline
parsing.
When the device family is provided without an explicit model number, we
simply choose the first available model. But since new models are being
added all the time, this default model is not guaranteed to remain the
same. That's not desirable because it can alter the behaviour of the
application.
The introduction of the Aeris 500AI is an example of this problem. The
default model in the vtpro family used to be the Oceanic Versa Pro. But
because the Aeris 500AI has a lower model number, it automatically
became the new default model. Since both use a different protocol
variant (MOD vs INTR) they are not interchangable.
The default model is now hardcoded. The best option is of course to
provide the model number explicitly!
Libdivecomputer always uses metric units internally. But when reverse
engineering a device that stores everything using imperial units, it's
very convenient to be able to switch the output to imperial units too.
The existing output code is removed and replaced with the new XML and
RAW output formats. The desired output format can be selected with a new
command-line option. The XML format remains the default output format.
The RAW output format exports each dive to a raw (binary) file. To
output multiple files, the filename is interpreted as a template and
should contain one or more placeholders.
