This bug seems not to have existed in our bfin code, thus
no change in this merge

Also move them to multimedia filters section.

Use verbal form to describe "outputs" options, and mention it in the
manual.

This is required since there are bit-inexact implementations
of the vp3 idct (for bfin).

This way, the special IDCT permutations are no longer needed. This
is similar to how H264 does it, and removes the dsputil dependency
imposed by the scantable code.

Also remove the unused type == 0 cases from the plain C version
of the idct.

While this change isn't bitexact, the IDCTs weren't bitexact to
start with either.

This simplifies decoupling vp3 from dsputil.

Just like get_buffer, get_format should not be called from a different
thread if thread_safe_callbacks is not set.

With the current code it fails due to running out
of registers.
So code the store offsets manually into the assembler
instead.
Passes "make fate-dts".

This simplifies the code and improves quality at the expense of a slight
slowdown of a rarely used function (no fate test uses it).

As the function arguments change, we also change the function name
to ensure that anyone using this (non public) function doesnt end
with hard to debug crashes. The new name also has a proper prefix.
