Sorry, that was rude and undeserved. I realize how much work it must be to
merge Anton's latest opus.

I rephrase it: until commit 79456652, channel_layout was the only
information about the number of channels in a buffer. Therefore, an
application that reads it and relies on it is valid. And since there was no
major bump since 79456652, the requirement still stands.

In fact, I do not see any field in AVFilterLink except channel_layout, so it
may still be the case now.
