Optimised C version of count_leading_zeros() taken from alac-0.1.1. This makes ALAC very close to realtime on the ipod (just the very occasional skip during disk reading - it is realtime when the disk is sleeping).

Codec makefile cleanup: remove redundant things, don't generate dependency files when cleaning.

Move code into IRAM and explicitly inline some functions (gcc was inlining them anyway, but this way is better)

Remove generic M4A parsing code from libalac and create a libm4a - so it can be used by other codecs

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.

Workaround for ALAC files that previousy wouldn't play. Libalac now skips unknown chunk IDs. Time display and seeking is broken for those files (the ones that played before still work). Patch by Alyssa Milburn.
