avfilter/internal: Don't include formats.h
...
internal.h doesn't rely on it; instead include it directly
in every user that needs it (a filter needing it is basically
equivalent to it using FILTER_QUERY_FUNC, i.e. a majority of
filters doesn't need it).

avfilter: Deduplicate default audio inputs/outputs
...
Lots of audio filters use very simple inputs or outputs:
An array with a single AVFilterPad whose name is "default"
and whose type is AVMEDIA_TYPE_AUDIO; 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 (4784B here) as well as relocations.
*: In fact, several filters (like the filters in af_biquads.c)
already use the same inputs; furthermore, ff_filter_alloc()
duplicates the input and output pads so that we do not even
work with the pads directly.
