[Bluez-devel] UNITINFO and SUBUNITINFO in avrcp

["Frédéric Dalleau" <frederic.dalleau@access-company.com>]

This little patch enables support of UNITINFO and SUBUNITINFO commands 
in audio service.
The implementation is not very useful itself but it is mandatory in AVRCP.

PTS has some test cases to check for it.

Comments are welcome!

Frédéric.
