    avutil/frame: add AVFrame.alpha_mode
FFmpeg currently handles alpha in a quasi-arbitrary way. Some filters/codecs
assume alpha is premultiplied, others assume it is independent. If there is
to be any hope for order in this chaos, we need to start by defining an enum
for the possible range of values.

    avfilter/avfiltergraph: allow different conversion filters per merger
Instead of hard-coding the assumption that all video properties are handled
by vf_scale, generalize the struct slightly to allow different conversion
filters for each property being merged. The avfiltergraph code creates a list
of conversion filters needed and inserts all of them at once.

Because a conversion filter might itself e.g. not support all formats,
it's possible that we need to go through the whole process of negotiating
formats multiple times, and keep adding conversion filters until all of them
are settled. Do this by simply jumping back to the beginning of the loop
to ensure that the `convertor_count` field remains contiguous.

    avfilter/vf_premultiply: signal correct alpha mode
Set the output link according to the chosen direction, and the input link
to its opposite (unless the input is not in-place, in which case there is no
alpha channel).

Also update the alpha mode on the output frame, since it may differ.

    avfilter/vf_premultiply: add dynamic variant of this filter
We need a filter that can premultiply and unpremultiply the alpha channel
dynamically, on demand, in response to the negotiated alpha mode, analogous
to how vf_scale operates. Introduce a new filter "vf_premultiply_dynamic"
that accomplishes this.

    avcodec/avcodec: add AVCodecContext.alpha_mode
Following in the footsteps of the previous commit, this commit adds the
new fields to AVCodecContext so we can start properly setting it on codecs,
as well as limiting the list of supported options to detect a format mismatch
during encode.

This commit also sets up the necessary infrastructure to start using the
newly added field in all codecs.

>
> In the visual effects industry premultiplied color channels are the norm,

    avfilter/vf_scale: set correct alpha mode after format change
While vf_scale cannot directly convert between premultiplied and straight
alpha, the effective tagging can still change as a result of a change in

    avfilter/vf_overlay: support premultiplied base layers
Conceptually, these are pretty simple to handle, since they are basically
equivalent to the case of alpha being absent, since the only thing the
destination alpha plane is used for is unpremultiplyng straight alpha.

For planar formats, the total number of cases doesn't change in principle,
since before this patch we have:

- alpha present, overlay straight
- alpha present, overlay premultiplied
- alpha absent, overlay straight
- alpha absent, overlay premultiplied

And now we have:

- main straight, overlay straight
- main straight, overlay premultiplied
- main premultiplied, overlay straight
- main premultiplied, overlay premultiplied

That said, we do gain some cases now that we used to (incorrectly) ignore,
like premultiplied yuva420p10.

Notably, we can skip defining separate functions for the case of main alpha
being absent, since that can be a single cheap branch inside the function
itself, on whether or not to also process the alpha plane. Otherwise, as long
as we treat "alpha absent" as "main premultiplied", the per-plane logic will
skip touching the nonexistent alpha plane.

The only format that actually needs extra cases is packed rgb, but that's only
two additional cases in total.

Also arguably simplifies the assignment logic massively.

    avfilter/vf_scale: require straight alpha for alpha blending
Fortunately, we only care if this flag is set - otherwise, this filter is
alpha mode agnostic (since it is purely scaling, etc).

That said, there is an argument to be made that we should prefer premul
alpha when scaling, because scaling in straight alpha will leak garbage
pixels; but I think that would be a too backwards-incompatible change to
be worth thinking about at this time.

    avfilter/vf_zscale: simplify and fix alpha handling
There's no reason to use a completely separate graph just to process the
alpha plane in isolation - zimg supports native alpha handling as part of the
main image.

Fixes several issues with this filter when adding or removing alpha planes,
and also adds support for scaling premultiplied alpha (which reduces artefacts
near the image borders).
