audio policy: volume control reorganization Output volume and routing control by AudioOutputDescriptor is reorganized to prepare hardware source volume and routing control. AudioOutputDescriptor contains all volume, device and activity state common to software (audio flinger mixers) and hardware sources (tuners, A2DP, HDMI). A new class SwAudioOutputDescriptor is derived from AudioOutputDescriptor and is specific to software sources. Low level routing and volume control methods receive an AudioOutputDescriptor parameter instead of an IO handle. mPrimaryOutput is now an AudioOutputDescriptor.
