min = FFMIN(min, avfilter_poll_frame(link->src->inputs[i]))
which, since FFMIN is a macro, was calling itself
twice for every input, causing an exponential cost in time.

Hopefully this fixes regression tests on DOS.
It breaks alignment of the output a bit more, but this should be easy to
fix with a second patch.

When called on a link with a filter whose destination pad has not a
get_video_buffer callback defined, it will call
avfilter_get_video_buffer() on the first output link of the
destination filer, rather than use avfilter_default_get_buffer(), so
the video buffer can be allocated forward in the filterchain.

Also add the w and h parameters to avfilter_get_video_buffer(), as the
minimum width and height requested by each filter in the filterchain
may change, this allows for example a memcpy-less pad filter.

This change breaks API / ABI backward compatibility.

See the thread:
"[PATCH] Implement recusive avfilter_get_video_buffer()".

Original commit message:
	Very evil missuse of svn to test if AVOption and AVOption2 are compatible.
	If this test triggers anywhere for anyone, revert this commit immedeatly.
	Ill revert this in a day or 2, its just so we know beforehand if the idea
	with the union is doable or not without breaking ABI/API.
