src_buffer.h => buffersrc.h (which already exists)
This may seem a bit inconsistent, yet it is the better scheme which I
could devise (being the filter itself called buffersrc/buffersink that
makes sense), also that would be consistent with buffersink.h and with
the other headers scheme.

On the same overall API consistency ground, that would be:
av_buffersink_get_buffer_ref()
av_buffersrc_add_buffer_ref()
_add_ref also is fine, provided that we make it consistent with the
buffersink API.
