Short windows are of length 256 and begin at sample 448.

This keeps the encoder from switching away from an wight short sequence
prematurely when attacks are detected two frames in a row. It also allows for
the legal and useful LONG_STOP_SEQUENCE to LONG_START_SEQUENCE transition.

16 subblocks (since we no longer need that), which should also lead to a
minor speedup.

Originally committed as revision 23854 to svn://svn.ffmpeg.org/ffmpeg/trunk

we apply them as 16x8/8x16/8x8 subblocks where possible. Since this allows
us to use width=8/16 instead of width=4 MC functions, we can now take more
advantage of SSE2/SSSE3 optimizations, leading to a total speedup for splitMV
filter of about 10%.

Two macros (WRITE_ARRAY and WRITE_ARRAY_2D) take the prefix (modifiers)
(not all tables are static, and they might not be constant either), the
type, and the name of the array. It'll be copied with same name and type,
and with the correct size of the currently-defined object.

This drops one parameter from the functions' macros, and require structures
to be typedeffed, but ensures that it is possible to map 1-to-1 the type to
the function name.

This functionality is better accessed through tools like oprofile.

Originally committed as revision 23808 to svn://svn.ffmpeg.org/ffmpeg/trunk

gprof is far too intrusive to be of use as a profile for ffmpeg,
and it fails to build in many configurations.  Oprofile is a
better tool for profiling on Linux.
