This file is only used by the greyedge filter and therefore
only compiled if said filter is enabled. This also allows
to remove a config_components.h inclusion, avoiding unnecessary
rebuilds.

Lots of video filters use a very simple input or output:
An array with a single AVFilterPad whose name is "default"
and whose type is AVMEDIA_TYPE_VIDEO; everything else is unset.
Given that we never use pointer equality for inputs or outputs*,
we can simply use a single AVFilterPad instead of dozens; this
even saves .data.rel.ro (8312B here) as well as relocations.
*: In fact, several filters (like the filters in vf_lut.c)
already use the same outputs; furthermore, ff_filter_alloc()
duplicates the input and output pads so that we do not even
work with the pads directly.

internal.h does not depend on video.h (and should not depend on it)
and therefore should not include video.h at all; instead all users
of video.h should include it directly.
Doing so also avoids unnecessary video.h inclusions in files that
don't need it, like most audio filters.

Otherwise the var_names and the corresponding enum will be off
and e.g. the array holding the variable values will be too small.

User may set color range / matrix coefficient set / primaries / transfer
characteristics for output.

Requires a new upstream function to test not for *import* support on a
given output pixel format, but also whether we can render to it.
