consistent with the allocation currently done for PIX_FMT_GRAY8
pictures.

No significant slow-downs have been measured.

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.

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.

NetBSD is unlikely to fix their headers and the FATE box passes it
as -D_NETBSD_SOURCE on the command line anyway. In this case, it's
better to keep the hack well-contained within this file.
Closes issue 886.

This test generates many output files, and keeping them separate
is convenient.

This reverts r22151.  It prevents the seektest from running at all and
is thus of no use whatsoever.
