This reverts commit f8bed30d8b. The reason
for this is that the overlap filter, which runs after IDCT, should run
on unclamped values, and thus IDCT and put_pixels() cannot be merged if
we want to attempt to be bitexact.
The attached patch fixes the jerky playback of VC-1 content with pulldown. The pulldown flags were incorrectly set. They must be correct in order to display the frames with the correct timing as mentioned in the specifications: "SMPTE 421M: VC-1 Compressed Video Bitstream Format and Decoding Process". More precisely the following tables:
Table 20: Progressive P picture layer bitstream for Advanced Profile
Table 22: Progressive B picture layer bitstream for Advanced Profile
Table 23: Progressive Skipped picture layer bitstream for Advanced Profile
Table 82: Interlaced Frame I and BI picture layer bitstream for Advanced Profile
Table 83: Interlaced Frame P picture layer bitstream for Advanced Profile
Table 84: Interlaced Frame B picture layer bitstream for Advanced Profile
Table 85: Picture Layer bitstream for Field 1 of Interlace Field Picture for Advanced Profile

Merging these functions allows merging some loops, which makes the
results (particularly after SIMD optimizations) much faster.
(cherry picked from commit f8bed30d8b)
In all 3 cases, the decoding continues and thus a warning would be sufficient.
Helps application that catch them with own log handers to handle them
accordingly.

Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

Includes mmx2 asm for the various functions.
Note that the actual idct still does not have an x86 SIMD implemtation.
For wmv3 files using regular idct, the decoder just falls back to simple_idct,
since simple_idct_dc doesn't exist (yet).

only avctx->{width,height} and don't touch coded_{width,height} when parsing
them. This fixes the case when coded and display dimensions differ by more
than one macroblock.

AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows
passing of packet-specific flags from demuxer to decoder, such as the keyframe
flag, which appears necessary to playback corePNG P-frames.
