audiopolicy: Add notification when default effects are updated
* In M, we now have the ability to define a default set of audio effect
on a per-stream basis. This allows us to get around the problem of
apps not sending the control intents so we can implement smart
global effects for specific media types.
* We still need a session id in order to get a handle and configure them
from an app like AudioFX, so we'll need to add some plumbing in
order to send an event to interested applications.
* This patch implements the native side of this. The Java layer will
call down thru AudioSystem and register a callback which will be
invoked by the audio policy when default effects are updated on
a stream. This callback will receive both the stream type as well
as the session id.
* Attaching this listener requires that the caller hold the
MODIFY_AUDIO_ROUTING permission.
