audio: From RTP point of view we can use one payload for HR/FR AMR
Remove the separation of half-rate and full-rate AMR. The used rate
can be found inside the AMR payload. The signalling of what kind of
traffic channel is used can be done with the GSM 08.08 Chosen
Channel IE in the Assignment Complete message.
This way I can use a fixed payload type in the MGCP GateWay but
have a mixed TCH/F and TCH/H config. E.g. use TCH/F FR3 for some
subscribers when connected to MSC A but use AMR5.9 on a TCH/F for
MSC B when all TCH/Hs are gone.
