mgw: accept zero-length RTP payload as BFI Mainline OsmoBTS now has an option (rtp continuous-streaming) that causes it to emit an RTP packet every 20 ms without gaps, sending a BFI marker in the form of zero-length RTP payload when it has nothing else to send. These codec-independent BFI markers don't indicate TAF, but this provision is a good start. Accept this BFI packet format in themwi-mgw.

/*
 * There are times when we hold open some UDP sockets, but can't do
 * anything with incoming packets other than discard them.  This
 * situation holds for dummy one-sided endpoints, for gateway
 * endpoints that haven't been fully connected yet, and for all RTCP
 * packets at the moment.
 *
 * In this module we implement the generic UDP "black hole" sink.
