Instead of writing packets sequentially and losing sync on any
frame gap, compute the write position from the VBAN header's
n_frames field. Out-of-order packets land at the correct
ringbuffer offset, matching how module-rtp handles this.
Only advance the writeindex when a packet extends the frontier
so that late arrivals fill gaps without moving the pointer
backwards.

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
