547d412078 avfilter: update some comments 
start_frame is no more, samplesref argument is now frame argument.

1655788712 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.

108b4de552 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.

39a09e995d lavfi: deprecate avfilter_link_set_closed(). 
Applications are not supposed to mess with links,
they should close the sinks.
Furthermore, this function does not distinguish what end
of the link caused the close and does not have a timestamp.

d03eab34dd lavfi: rename link.current_pts to current_pts_us. 
This field is used for fast comparison between link ages,
it is in AV_TIME_BASE units, in other words microseconds,
µs =~ us.
Renaming it allows a second field in link time base units.

2a351f6c55 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.

838bd73139 lavfi: create Libav-API compatibility layer for avfilter_graph_parse() at the next bump 
Add function avfilter_graph_parse_ptr() and favor it in place of
avfilter_graph_parse(), which will be restored with the old/Libav
signature at the next bump.

If HAVE_INCOMPATIBLE_LIBAV_API is enabled it will use the
Libav-compatible signature for avfilter_graph_parse().

At the next major bump the current implementation of
avfilter_graph_parse() should be dropped in favor of the Libav/old
implementation.

Should address trac ticket #2672.

1776177b7f lavfi: replace passthrough_filter_frame with a flag. 
With the introduction of AVFilterContext->is_disabled, we can simplify
the custom passthrough mode in filters.

This commit is technically a small compat break, but the timeline was
introduced very recently.
