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.
