prepare gapk for dealing with variable-length frames
...
The existing architecture was modelled around fixed-length codec frame
sizes, which of course fails with multi-rate codecs such as AMR.

RTP: give meaningful error messages if something fails
...
In fact, it should probably be better to silently ignore all those
errors as opposed to aborting the entire processing queue? But that's
for another patch...

This enables benchmarking of the codec. It will print
the amount of CPU cycles needed for encoding/decoding a single
20ms frame on average.

gapk: make sure the output file is closed/flushed on ctrl+c
...
This is useful particularly in case you are reading from RTP and writing
to a file, and don't want truncated codec frames in your file.

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.
