Remove dependency on libsndfile

Browse Source 
Wav files include the length of the data in the file header. libsndfile
expects this length to be there and be sane. Unfortunately, when piping
data from avconv, this length is dummied out because the full length is
not known yet, so libsndfile can't be used to process a pipe data
stream. This removes the libsndfile dependency and replaces the used
functions with hand written ones.
