Rough merge of upstream libdivecomputer.
This is mainly about making the new iostream code upstream, although we
don't actually use it.
It abstracts out the the old serial and usbhid code, but we end up still
using our own 'custom_io' interface because the iostream code doesn't do
it right.
* jef/master:
Correctly determine git SHA if libdivecomputer is a git submodule
Don't accept a NULL pointer as parameter
Add support for semi-closed circuit diving
Detect dives with invalid profile data
Implement the serial communication functions as no-ops
Move the socket code to a common file
Add support for a custom I/O implementation
Port the USB HID code to the new I/O interface
Port the bluetooth code to the new I/O interface
Port the IrDA code to the new I/O interface
Port the serial code to the new I/O interface
Add a new abstract I/O interface
Post release version bump to 0.7.0
Sync up with upstream cersion 0.6.0.
Annoying merge, mainly because a lof of the changes Jef had done are
actually changes that came from our Subsurface branch, but in a
different form, because Jef doesn't actually take patches directly from
us.
Why? I don't know.
* tag 'v0.6.0' of git://git.libdivecomputer.org/libdivecomputer:
Release version 0.6.0
Fix some potential buffer overflows
Fix some casts with constant pointers
Enable some useful compiler warnings by default
Generate html documentation from the manpages
Fix the decoding of the ndl/deco information
Decode the firmware version for the iDive series
Add support for the Suunto Eon Core
Locate the most recent dive
Add EON Steel time sync capability
Improve the progress events
Detect the model number using the hardware type
Shearwater: add support for remaining gas time
Shearwater: extract tank sensor data for log version 7
Shearwater: extract log version from header
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.

Merge with upstream libdivecomputer from Jef:
- more Cochran work from John Van Ostrand
- new 'timesync' interface to synchronize the clock on a dive computer
- support for Aqualung i200
- misc updates (Cressi Leonardo fix, OSTC 3+ renaming, fix surface pressure on iX3M, idive salinity parsing)
- HIDAPI work.
It turns out that HIDAPI is not compatible with libusb in the actual
packet sending path, so this will need some more cleanups - Jef doesn't
see the issue because he doesn't have a generic packet IO layer and
doesn't share packets with the BLE code.

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.
This teaches the dctool about the subsurface special field strings, and
saves them in the xml output in a way which is compatible with
subsurface.

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.
