TRAU frame RTP conversion
This adds code that converts codec frames between (decoded) TRAU format
and RTP payload format. The FR + EFR functions have been lifted from
OsmoNITB and exended slightly.
The HR functions have been written from scratch. There is also
incomplete code for AMR that needs to be completed + tested.
