audio policy: add support for external audio sources Add support for activity on external audio sources. An external source reflects activity on an input audio device that must be controlled (both routing and volume) by the audio policy manager. First, the input device must be connected with setDeviceConnectionState(). Then, the source activity is indicated with startAudioSource() and stopAudioSource() APIs. startAudioSource() indicates the source device with an audio port configuration and the use case by the audio attributes. Once a source is active, its routing and volume are controlled by the policy manager as it would for a software source (AudioTrack). Change-Id: If5805d58a4356b2f681f1aabf54375f62b55b98a
