Double motion vector range for HPEL interlaced picture in proper place

The existing code is not in the right place and it should cover both
interlaced frame and field pictures.

vc1: fix VC-1 Pulldown handling.
...
Pulldown flags are being set incorrectly and AVFrame->repeat_pict is not
being set. Also, skipped frames exit header parsing too early and do not
set pulldown flags appropriately. Ticks_per_frame needs to be set and
time_base adjusted so player can extend frame duration by a field time.
This fixes problems encountered when attempting to transcode HD-DVD EVOB
files with HandBrake. Also makes these files play smoothly in avplay.

doxygen: Prefer member groups over grouping into modules
...
Before this, almost all module groups have been used for grouping functions
and fields in structures semantically. This causes them to not appear
properly in the file documentation and needlessly clutters up the "Modules"
index.
Additionally, this commit streamlines some spelling and appearances.

Revert "VC1: merge idct8x8, coeff adjustments and put_pixels."
...
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.

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).
