This adds a new method, exclusive to transports created by the Broadcast
Sink. It allows the user to terminate the sync to a BIS, via a 2 step
process. The first step is the call to this method, which changes the
transport's state to idle, with the second step being done by the audio
server which detects this change and releases the transport.
