Some of the more common errors (caused by packet loss, network jitter, ...)
should be reported with INFO unless there is some indication about how
to fix the problem.
Fixes#4559
Always listen on the receive socket. Find the stream with the given
stream_name of the packet and create it if it doesn't exist.
Also take the sample-rate, channels and format from the packet
parameters instead of the config.
Fixes#4400
