I do not like that, I prefer AVFrame to keep it as is currently.
frame allocation can be moved elsewhere.

We introduced a ff_horiz_slice_avx2/512() implemented on a new algorithm.
In a nutshell, the new algorithm does three things, gathering data from
8/16 rows, blurring data, and scattering data back to the image buffer.
Here we used a customized transpose 8x8/16x16 to avoid the huge overhead

Intrusive? You call that intrusive?
Anyway, here is a way to make it even less intrusive: Use "type *prv =
&p[c]" and don't modify the inner loop at all (and don't update prev
after the loop). I
This patch is too much intrusive to be acceptable.

AVFrame.metadata is always owned by its AVFrame, it is not shared
in the first place, so one does not need to make the frame writable
to modify it.

Up until now, the aderivative and aintegrate filters allocated
an audio buffer with exactly one sample per channel via
ff_get_audio_buffer(); if said buffer could not be allocated,
a frame would leak, as freeing it has been forgotten.
This commit instead uses a plain array for the audio buffer; it
