Interface between audio server and vibrator service
The haptic playback should be controlled by vibrator service. Via the
interface, audio server could notify vibrator service about starting or
stopping haptic playback and get vibrator intensity from vibrator
service. Vibrator service could call mute/unmute to control the haptic
playback.
