Add support for encoding adpcm_ima_apm and muxing to apm.

If possible, I would like to get this functionality into the 4.3
release.

v3: [4][5][6]
* Support both extradata formats
  - fixes FATE failure + preserves compatibility
* EINVAL->ERANGE

v2: [1][2][3]
* fix mixed declarations and code
* remove unused variable
* fix array initialisation
* LOG_WARNING->LOG_ERROR
* reorder "name and probe fix"
