unfinished, iam just commiting this so the functions that should be
non static have prototypes.

Also fix function definitions to match prototypes (missing const).

These functions are not used outside their respective files, and they
lack a prototype in a header.

These macros are redundant.  All uses are replaced with the generic
DECLARE_ALIGNED macro instead.

Originally committed as revision 22233 to svn://svn.ffmpeg.org/ffmpeg/trunk

These macros naturally belong next to the generic DECLARE_ALIGNED
macro.

Originally committed as revision 22192 to svn://svn.ffmpeg.org/ffmpeg/trunk

This is generally around 12% faster than the prior method of creating a
linked list for each block as tokens are read, but can be anywhere from
8% to 28% faster depending on file and CPU.

Originally committed as revision 22190 to svn://svn.ffmpeg.org/ffmpeg/trunk

This increases the slice size to 64 pixels, due to having to decode an
entire chroma superblock row per slice.

This can be up to 6% slower depending on clip and CPU, but is necessary
for future optimizations that gain significantly more than was lost.
