Initial check-inmarlin_12.91.0marlin/12.91.012.91.0

GLib based interface library for BlueZ, factored out of the
agl-service-bluetooth binding code.  See README.md for build and usage
notes and the mapping of the new source files to those in the binding
if that is for some reason required.

Currently untested functionality:
* autoconnect on startup
* mediaplayer controls

Bug-AGL: SPEC-4182
