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.

For the default table we keep using the exact previous
coefficients, this way individual functions can be updated seperately
without breaking fate

dsputil_init() is deprecated and not meant to be exported.
ff_dsputil_init() is internal to libavcodec and thus can not be used.
avpriv_dsputil_init() is the version shared between libraries.
This commit fixes 3 unjustified libavfilter deprecated warnings.
The next commit will introduce a proper decimation filter to be used
along with the field matching filter. To avoid confusion with this
filter which has currently a very limited usage (and will not work
properly with the fieldmatching filter), the new decimation filter will
take the decimate name, and this filter is renamed to mpdecimate.
avpriv_request_sample() and avpriv_report_missing_feature() were printing bogus values for the extra arguments.
