The new overlap smooting filter smoothes image pixels stored in v->block.
Switch to v->block instead of s->block for storing decoded image pixels for P
frames. Additionally, we must take incrementing *_blk_idx out of the
vc1_put_signed_blocks_clamped function.

Keyframe detection was inverted in cfe1a9d3 in order to fix keyframe
flags set for the sample attached to trac #7091. However, that sample is
errantly muxed.

As noted at
https://web.archive.org/web/20020803104640/http://www.pcisys.net:80/~melanson/codecs/film-format.txt,
the original keyframe detection logic is correct, and this patch
restores it.

For filters based on framesync, the input frame was managed
by framesync, so we should not directly keep and destroy it,
instead we make a clone of it here, or else double-free will occur.
But for other filters not based on framesync, we still need to
free the input frame inside filter_frame.

The existing version which was cherry-picked from Libav does not work
with FFmpeg framework, because ff_request_frame() was totally
different between Libav (recursive) and FFmpeg (non-recursive).
The existing overlay_qsv implementation depends on the recursive version
of ff_request_frame to trigger immediate call to request_frame() on input pad.
But this has been removed in FFmpeg since "lavfi: make request_frame() non-recursive."
Now that we have handy framesync support in FFmpeg, so I make it work
based on framesync. Some other fixing which is also needed to make
overlay_qsv work are put in a separate patch.
