gapk: Add support for RTP input/output streams

Instead of having only file-based I/O, this enables gapk to receive and
send RTP streams, e.g. from live GSM network equipment like
sysmoBTS/nanoBTS.

Support is currently simplistic.  On transmit, there is hard-coded codec
type of full-rate GSM.  On receive-side, we should auto-detect the
format based on frame size and/or payload type, but we don't do that yet
at all.
