The tests previously rounded the timestamps. Its better in a fate test to preserve
the data from the demuxer and decoder.

The horizontal pass get ~2x performance with the patch
under single thread.

Tested overall performance using the command(avx2 enabled):
./ffmpeg -i 1080p.mp4 -vf gblur -f null /dev/null
./ffmpeg -i 1080p.mp4 -vf gblur=threads=1 -f null /dev/null
For single thread, the fps improves from 43 to 60, about 40%.
For multi-thread, the fps improves from 110 to 130, about 20%.

READ has already been undefined at this point; it is obviously intended

While the VAProcColorProperties structure was added in libva 2.1, the
colour primaries/transfer/space fields were not added until libva 2.3.

Matroska EBML IDs can be only four bytes long maximally, so it is
natural to use uint32_t for them. By doing this and rearranging the
elements of the MatroskaLevel1Element structure, one can reduce the size
of said structure.

Notice that this field is not read via the generic reading process for
EBML_UINT, so one is not forced to use an uint64_t for it.

generated some warnings with clang and will cause alignment problems
with some parameter buffer types.

    return -(errorcode);
}
/* normal actions */
