Subject: [PATCH] client/player: Expose transport 'Unselect' method to the user

This exposes the 'Unselect' method for Broadcast transports. This
allows the user to terminate the sync to a specific 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.
