refactor: use msgb to receive, pass and send RTP packets
Instead of numerous arguments (buf, len and context data), use a msgb, like
most other osmo programs do, with a msb->cb pointing at a context data struct.
This opens the future for adding/stripping IuUP header data from the msgb
easily.
(Checked to pass current ttcn3-mgw-tests.)
