Avoid using AV_PIX_FMT_NB, since that hardcodes the number of pixel
formats into lavfi and will break when a shared lavu is updated, adding
new pixel formats.

Use the formats.h API instead.

This is more consistent with naming in the rest of Libav.

This is shorter and consistent across filters.

Any alleged performance benefits gained from the split are purely
mythological and do not justify added code complexity.

A number of compilers, for example those from TI and IBM, choke on
these initialisers.  The current style is also quite ugly.

It is not used in any filters currently and is inherently evil. If
passing binary data to filters is required in the future, it should be
done with some AVOptions-based system.

It will allow adding new fields to it without ABI breaks.

It is only useful inside filters and we don't allow user filters for
now.

Those functions are only useful inside filters. It is better to not
support user filters until the API is more stable.

Avoid the need to implement slice direction detection code, thus
reducing code duplication.
