lavfi: make request_frame() non-recursive.
...
Instead of calling the input filter request_frame() method,
ff_request_frame() now marks the link and returns immediately.
buffersink is changed to activate the marked filters until
a frame is obtained.

lavfi: replace link.closed by link.status.
...
The status field can carry any error code instead of just EOF.
Also only update it through a wrapper function and provide a timestamp.
Update the few filters that used it directly.

lavfi: drop the requirement that request_frame returns a frame.
...
It requires a loop in filters or the framework,
that makes the scheduling less efficient and more complex.
This is purely an internal change since the loop is now
present in buffersink.
Note that no filter except buffersink did rely on the requirement.

Since we do not support "standalone" filters not attached to an

filters. In addition that function is horribly named, the action it does
