backend-native: implement volume control

System Internals / PulseAudio - Wim Taymans [gmail.com] - 31 October 2014 00:16 UTC

Parse the gain changed AT commands from the headset and fire 2 new hooks as a result. The device will connect to those hooks and change the source/sink volumes.

When the source/sink volume changes, set the gain on the microphone or speaker respectively. Make sure we do nothing if the transport can not handle the gain changes.
