Rearrange the MDCT library lookup tables so that codecs can access them. Access them in cook. Remove old cook trig tables. Replace old 32x16 bit fixed point multiply code with faster ASM ARM/Coldfire versions using full 32 bit precision. Improves performance signficantly on PP5024 (~200% realtime for a 64k file) while saving a lot of memory and improving accuracy.

-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.
