85aad9b397 Extend av_log2 in codeclib into a generic for scanning for set bits, which can provide either log2 or leading-zero-count output, and can force mapping 0 input to 0 output if needed (otherwise 0 input produces undefined result). Replace av_log2 in lib/codeclib.h, floor_log2 and wl_min_lzc in libfaad/common.c and common.h, and count_leading_zeros in libalac/alac.c with macros using bs_generic.

2e6d604bb6 Stop hiding errors by redirecting stderr to /dev/null. If we really need to do re-introduce somewhere we should rather make it dependent on the V variable so that make V=1 would still show the error and only "normal" builds would hide it.

c6b3d38a15 New makefile solution: A single invocation of 'make' to build the entire tree. Fully controlled dependencies give faster and more correct recompiles.
Many #include lines adjusted to conform to the new standards.

aaacb7010f Remove the mallocs for the codecdata in the m4a parser and assume a maximum size of 64 bytes (see comments in source). Also clean up the alac_set_info() function a little and make it alignment-safe. We still need to remove the seektable related mallocs. Please report if any AAC or ALAC files stop playing in Rockbox after this commit - but it is not expected to cause problems.

02da4e6130 Update several codec Makefiles so that the codec libs build again on Coldfire targets, after the recent move of system-related things to the target tree. (Note to admins: make errors aren't detected on the CVS build page. :))

a796260a6b Next step of Makefile tuning: * Use 'make' internal commands for printing messages. Saves build time especially on cygwin. * SILENT variable used in more places. * Bitmap build system uses one Makefille less.

347992e9d9 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).

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.

9f41c6c11e 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.
