Merge git://git.libdivecomputer.org/libdivecomputer into Subsurface-branch

Browse Source 
Merge with Jef's upstream libdivecomputer:

 - some OSTC parsing fixes, including getting the initial CNS into the
   first sample

 - syntactic cleanups to the Scubapro Aladin Sport Matrix support to
   match upstream

* git://git.libdivecomputer.org/libdivecomputer:
  OSTC: initialize initial CNS from header
  Use an out-of-range value as undefined
  Support for the Scubapro Aladin Sport Matrix.
