c4415f6ec9 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).

63b61d55f9 vf_unsharp: fix out-of-buffer read 
In apply_unsharp(), when y is >= height, prevent out-of-buffer reading
from src, read from the last buffer line in src2 instead.

The check was implemented in the original unsharp libmpcodecs code and
lost in the port.

This also fixes output discrepancy between the two filters.
