18b6a69ce9 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.

c402ce418a Remove lowres support from wmv2 decoder
lowres option crashes with wmv2 files which I have for test,
so I think it's better to remove the support to the time when
lowres will be really supported by this codec

3b4621acbb Fix init_get_bits length argument for init_get_bits.
Do not use rlelen for buffer size in init_get_bits, it is
only the size of the data for the first field.
Since it is not reliable, just use the size of the whole buffer.
Additional comments add removal of unused rlelen variable by
Reimar Döffinger.

cf16104ad1 Change guess_palette so its output matches the most common palette.
This means it uses full brightness range and brightness
increasing instead of decreasing with index of non-opaque
color.

ad1862d64a ALPHA: Replace sized int_fast integer types with plain int/unsigned.
int/unsigned is the natural memory access type for CPUs, using sized types
for temporary variables, counters and similar just increases code size and
can possibly cause a slowdown.

Although AC-3 allows it, it's not very useful. The encoder uses the same code

It was only needed at low bitrates, which now already use a low bandwidth, so
