mgcp: Add RTP audio transcoding
This patch implements audio transcoding between the formats GSM,
PCMA, L16, and optionally G.729.
The feature needs to be enabled by using the autoconf option
'--enable-mgcp-transcoding'. In this case mgcp_transcode.c will
be compiled and linked to osmo-bsc_mgcp, and the transcoding
functions provided will be registered as processing callbacks.
If G.729 support is required, libcg729 needs to be installed and
'--with-g729' must be passed to ./configure.
