f1844c4166 1) Always enable the DSP. 2) Change codec to output one 32-bit array per channel containing samples left-shifted to 28-bits (instead of 16-bit interleaved samples). 3) Remove the two 16KB internal predicterror_buffer arrays (we use the output arrays instead) 4) Small internal rearrangement of the code.

c91e0bbfc9 Cleaned up the messy codec header and library system by merging codec.h, lib/codeclib.[ch] and lib/xxx2wav.[ch] into just codeclib.[ch]. Deleted much of the unused code in the xxx2wav portion. All codecs should now only include codeclib.h, and whatever codec specific headers are needed.
