[RFC v8 2/9] audio: Simplify org.bluez.Headset

["Frédéric Danis" <frederic.danis@linux.intel.com>]

Simplify org.bluez.Headset interface by removing methods, signal and
properties which should be managed by external telephony program.
In audio/headset.[ch], remove functions no more used by telephony
drivers.

Move SpeakerGain and MicrophoneGain properties to Media Transport.
