Extend the audio HAL interface to support get/set master mute
(cherry picked from commit d245968b7ef0be5c776c9aefff3eca9e293d1b35)
> Extend the audio HAL interface to support get/set master mute

> Hand merge from ics-aah

> > Extend the audio HAL interface to allow HALs to optionally support HW
> > level master mute. This follows the same pattern as master volume and
> > is part of the fix for bug 6828363. Because of the divergences
> > between ICS and master, this change will need to be merged by hand.
