@xyz reported a regression on his Sony Xperia Z3 Tablet Compact where
playback would intermittently fail to start, essentially deadlocking in
the decoder. Bisecting narrowed down the issue to this commit, which was
meant as an optimization but is not necessary.
This reverts commit a75bb5496a.

Split vtenc_init() into vtenc_init() (VTEncContext initialization) and
vtenc_configure_encoder() (creates the vt session).
This commit will allow to restart the vt session while encoding.

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.

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.
Fixes ticket #7171.
