audiopolicy: Add AudioSessionInfo API
* This patch introduces a new API which allows applications to
query the state of the audio effects system, and receive
callbacks with the necessary information to attach effects
to any stream.
* In the future, this may come as part of the AudioPort system,
but since that's an active area of development by Google, we
will dodge it for now.
* The policy now simply keeps a refcounted list of objects which
hold various bits of stream metadata. Callbacks are sent on
stream open/close to applications which might be listening
for them.

audiopolicy: Constrain session events to music streams
* We're really only interested in music streams right now, but
events are being generated for all streams (system sounds, etc).
* Constrain for now, in the future we will filter based on client
registrations.

audiopolicy: Use audio_session_t consistently for AudioSessionInfo
In N, the usage of audio_session_t was made more consistent in the
commit d848eb48c121c119e8ba7583efc75415fe102570.
Do the same for the AudioSessionInfo API.
