Add enums for handling libsndfile mp3 encoding
MP3 support was introduced in libsndfile 1.1.0 . It will be a simple alternative to using external ffmpeg. To avoid dependency on the new libsndfile or config-time checking, hardcode the constants from sndfile.h . The actual availability will have to be checked at runtime.
