32c59a115d lavfi: do not call ff_filter_frame() with activate. 
avfilter_graph_request_oldest() does work that should be done by
either the filter or the application.

The principle of this function, calling ff_request_frame() from
outside the filter was always shaky. This version is less elegant
since it requires making special cases for each filter, but it
is more robust since it no longer calls ff_request_frame()
directly without notifying the filter.

Eventually, avfilter_graph_request_oldest() will be deprecated
for a function to just run the graph.

c619a4e525 lavfi: make two functions static.

ae4650f0b9 lavfi: disallow ff_request_frame for filters using activate.

d3cb140433 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.

28c62df672 lavfi: implement ff_inlink_make_frame_writable(). 
Unlike av_frame_is_writable(), it uses the link's alloc callback,
making direct rendering possible.

trivial changes.
