demux, stream: ignore packets and errors on forced exit

Browse Source 
When this happens, network calls are forcibly aborted (more or less),
but demuxers might keep going, as most of them do not check for forced
exits properly. This can possibly lead to broken packets being added.
Also do not attempt to read more packets in this situation.

Also do not print a stream open failed message if opening was aborted
anyway.
