Merge upstream updates from Jef Driesen:
- Deepblu Cosmiq+ support has been merged upstream
- Oceans S1 support has been merged upstream
- Various new models supported: Cressi Donatello, Scubapro G2 TEK, new
Excursion v6+ firmware.
- misc core changes, most notably supporting a new annoying specialized
binary format for "decomode", because Jef still can't deal with
strings.
- lots of small details

Report the decompression algorithm (Buhlmann, VPM, RGBM or DCIEM), and
if available also the parameters. For now only the conservatism setting
is supported, and for the Buhlmann algorithm also the Gradient Factors
(GF).

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.

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.
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.
