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. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@20922 a1c6a512-1295-4272-9138-f99709370657
