codec_pref: handle S0-S15 in ASSIGNMENT REQUEST
Opposed to all other codecs that are common in GSM, AMR requires a codec
configuration that is expressed by a bitmask (S0 to S15) in the speech
codec list in the ASSIGNMENT REQUEST. Also the BSC acknowledges those
configuration in the ASSIGNMENT COMPLETE message.
At the moment osmo-bsc ignores all incoming configuration bits. The bits
in the ASSIGNMENT COMPLETE speech codec (choosen) field are hardcoded.
- Store the configuration bits while parsing the ASSIGNMENT COMPLETE
- Create an intersection with the configuration that is actually
supported by the BSS
- Return the resulting (chosen) configuration bits with the assignment
complete message.
- Use the (highest of the) agreed codec rates in RSL channel activation.
