From 49ba646d579a89d5ff0e4f3d5eea237eea22aafd Mon Sep 17 00:00:00 2001

Subject: -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.
