mgcp: Remove the old MGCP based transcoding interface
Back in the day we worked around a field proven jitter buffer by
transcoding AMR to AMR with the MTN4200 and by this fixing RTP
timing as this device had:
a.) A working and stable time (generating RTP every N ms)
b.) A working jitter buffer
The code has probably rotted, it never retried MGCP commands sent
to the transcoder and it is not deployed either. Simplify the code
by removing it. If we ever need it back we can use the new transcoding
API to keep the state there. I think this code will not be missed
but the PerformanceTechnology Hard- and Firmware was rather nice.

mgcp: Simplify and shorten routine names
Now they are included in a struct we can just call them setup, process
and get_net_downlink_format to manage the lifetime.

mgcp: Move the transcoding routines into a struct
We will have the NOOP implementation (e.g. used by the NAT), the
SW implementation (using software codecs), a HW assisted one that
will use a DSP to do transcoding and in theory the RTP based one
(but I will remove that code).
