Internal API, available through AudioManagerInternal, to flag
a UID as having lost the ability to play audio. When that
happens, all players associated with this UID are paused, and
future players are immediately paused when they report they
started.
Users of this API must "enable" a previously banned UID when
it is no longer in use.
Test: upcoming manual test with background apps
