lavfi: unify asink_buffer and vsink_buffer API

The new API is more generic (no distinction between audio/video for
pulling frames), and avoids code duplication.

A backward compatibility layer is kept for avoiding tools ABI breaks
(only for the video binary interface, audio interface was never used
in the tools).
