This patch refactors the flow for the BAP Broadcast Sink. After discovering a new Broadcast Source a short PA Sync will be tried. Depending on the BASE information present in the PA and the local PACS capabilities of the Sink, one remote media endpoint will be created for each compatible BIS. Configuring one of these endpoints results in creating a stream and a media transport for the corresponding BIS. Idle timer. This patch introduces an idle timer, responsible for processing PA Sync requests. One request is possible at a time. When a broadcast source is discovered a new request for short PA sync is enqueued. Also, when a SetConfiguration is requested for an existing BAP broadcast source endpoint another request is enqueued. The timer runs periodically and peeks for requests. In case there is no request in progress the timer marks the already peeked request to pending and starts processing it. When the request is completed, it is removed from the timer's queue, so that the next request can be processed.
