    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).
