a8d1cfdec8 Approx 10% speedup in cook on files tested: Remove some inner loops in favour of memcpy/memset/vect_add calls; remove multiplication from index arithmetic in loops in favour of pointer arithmetic; make use of the MULT31, MULT31_SHIFT15 and CLIP_TO_15 implementations from codelib instead of having their own implementations in cook

bd9156a4ad Remove a divide in the cook's init function. Harmless but might as well drop it.

e184ef1027 Adding support for rm playback. Only cook codec is supported for now and no seeking.

49ba646d57 -Remove all dynamic allocations, hence remove cook_decode_close() which was basically 
needed for freeing allocated memory.
-Remove any ffmpeg-specific attributes (av_const,av_always_inline .. etc.).
-Move some math functions to cook_fixpoint.h - libavutil/common.h is no longer 
needed.
-Remove libavutil/mem.[c/h], libavutil/common.h and libavutil/internal.h.
-Fix a warning in cookdata_fixpoint.h.

f2c18d6922 -Remove calls to av_log() and use DEBUGF/printf instead, thuse removing 
libavutil/log.[c/h] and libavutil/avutil.h.
-Take necessary defines to bitstream.h from libavutil/intreadwrite.h to 
remove the latter.

0cb3ad58b3 -Took cook_random() from an old cook.c revision [6 mar 2007], which is a 
simple RNG, to eliminate the need for lfg.c/h.
-Remove lfg.c/h and md5.c/h as they are no longer needed and use the 
more common form of my name in docs/COMMITTERS.

67695617a1 The first part of Mohamed Tarek's Google Summer of Code work to implement RealAudio support in Rockbox. This is a self-contained Cook decoder using the original ffmpeg (still floating point) decoder and a new RM parser started by me in 2008 and continued by MT over the past few months. This is the equivalent of libcook.patch1 from FS#10182, but with further cleaning by both MT and me to minimise the differences to the original ffmpeg files. See README.rockbox for more details.

69db01e72f Initial commit of the minimal set of ffmpeg (r18079) files required for Cook (realaudio) decoding. These are the unmodified versions from ffmpeg, committed as a base for future changes.
