Add IAudioManager methods for tracking client recording activity
audio_unique_id_t IAudioManager::trackRecorder(IBinder token)
- registers a client recorder withing Audio Service,
returns a unique tracking recording ID (RIID);
Audio Service tracks the lifetime of the recorder using
the provided token.
oneway recorderEvent(int riid, int event)
- updates the current state of the client;
only "started" and "stoped" states are considered.
