Such a pool does not belong in the video format update, where it would be 
created even for decoders that don't need it, and/or cannot use it.

That includes VA, indeed. But it also includes any decoder where the allocated 
picture buffer format may (transiently) not match the decoded picture format 
due to format change.

For backward source compatibility, decoder_NewPicture() is already de-inlined. 
Now you just need to remove video.buffer_new and handle buffer management 
generically there, using a pool or whatever turns out to be most suitable.
