lavfi: move ff_update_link_current_pts() into the utility functions.
...
It does not change anything for the existing filters and makes
better code fatrorization when future code will use the utility
functions.

Unlike av_frame_is_writable(), it uses the link's alloc callback,
making direct rendering possible.

lavfi: avfilter_graph_request_oldest: request a frame again before returning.
...
With min_samples, if a frame arrives but is too small, it clears
frame_wanted_out. In most cases, the destination filter would be
activated again later because of frame_wanted_out on its own
outputs, but not sinks.
avfilter_graph_request_oldest() is doing the work of the sink
itself, and is therefore allowed to use frame_blocked_in.

lavfi: make filter_frame non-recursive.
...
A lot of changes happen at the same time:
- Add a framequeue fifo to AVFilterLink.
- split AVFilterLink.status into status_in and status_out: requires
changes to the few filters and programs that use it directly
(f_interleave, split, filtfmts).
- Add a field ready to AVFilterContext, marking when the filter is ready
and its activation priority.
- Add flags to mark blocked links.
- Change ff_filter_frame() to enqueue the frame.
- Change all filtering functions to update the ready field and the
blocked flags.
- Update ff_filter_graph_run_once() to use the ready field.
- buffersrc: always push the frame immediately.
