Merge branch 'master' of git://git.libdivecomputer.org/libdivecomputer into Subsurface-branch

Browse Source 
Merge with upstream libdivecomputer from Jef:

 - Jef merged my Scubapro G2 work, but renamed everything, and didn't
   get the newer IO model code. Very annoying.

   I went along with changing the G2 model family name to
   DC_FAMILY_UWATEC_G2 just to keep some of the basic infrastructure
   more easily mergeable.  But his uwatec_g2 version is not usable.

 - Cochran updates from John Van Ostrand

 - Misc improvements from Jef:
    * divesystems idive improvements
    * Oceanic OCS freedive mode
    * ppO2 callback cleanup

 - Some transport type work:
    * changes to IRDA configuration
    * basic bluetooth rfcomm transport mode

* 'master' of git://git.libdivecomputer.org/libdivecomputer: (35 commits)
  Removed unused code
  Fixed duplicate gasmix event reports
  Added decompression event handling for the Commander
  Fix bad profiles when profile ringbuffer wraps around
  Changed cochran_comander_profile_size function parameters
  Fixed location and encoding of Commander II pointers
  Use a local variable for the layout pointer
  Add new EMC device model string
  Add support for Pre-21000 s/n Commander dive computers
  Fix problems with wrapped logbook ringbuffer
  Retry read operations on failure
  Change profile download to be incremental
  Fix the id string offset
  Fix the progress events
  Use the trimix data format
  Use the correct model number
  Enable more fine grained progress events
  Abort with an error if the buffer is too small
  Use the standard libdivecomputer error codes
  Scubapro G2: add missed command packet logging
  ...
