Change vc1_decode_i_blocks to use vc1_put_blocks_clamped and
ff_vc1_i_loop_filter.

Simple and Main Profile also need unsigned put_pixels_clamped. Add an argument
to choose between signed and unsigned put_pixels and change function name to
vc1_put_blocks_clamped.

This reverts commit 2065317d.

I committed a wrong version of this patch.
Also reverts the follow-up commits 77a3dfb3 and 8331e591.

When using hardware accelerated decoding for multi-slice field interlaced pictures,
only the first slice was decoded. This patch adds the neccesary looping over the
remaining slices that may exist in field interlaced pictures. Additionally, we align
the calculation of mby_start for the second field with the method given in VC-1 spec.

Contrary to VC-1 spec, VAAPI expects the row address of the first
macroblock row in the first slice to start from zero for the second
field in a field interlaced picture.

Overlap filtering I and BI frames for Simple and Main profile is only
dependent on PQUANT. Restrict testing for CONDOVER and OVERFLAGS to
advanced profile. Change from mb_width to end_mb_x in ff_vc1_i_loop_filter
to avoid breaking the Microsoft Screen 2 decoder.

The v_overlap_filter needs to run on the colocated block of the previous
macroblock. For the luma plane, the colocated block is located two blocks
on the left instead of one. In addition, the overlap filter needs to run
on the non-edge blocks of the first macroblock row and column.

verify that the stco atom is upgraded to co64 when the addition of moov
size to the offsets results in an overflow
Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

when the last offsets in the stco atom are close to 4GB, the addition of
the moov atom size can overflow, causing corruption near the end of the
mp4 file.
this patch upgrades all stco atoms to co64 when such an edge case is
detected. in order to accomplish this, the implementation was changed to
walk the atom tree, instead of searching for the strings 'stco'/'co64'.
this was required since when an stco atom is changed to co64, its size
changes, and the sizes of all containing atoms (moov, trak, etc.) have
to be updated as well.
