f5a9c63401 lavfi: guess a timestamp for compat status change. 
Use the earliest input with the same status.
If that fails, print a warning and use the earliest source.
With this change, simple filter forward correctly the timestamp
of EOF.
Filters that are supposed to change it should be updated to
actually forward it.

fc3a03fcf9 avfilter: take_samples: do not directly return frame when samples are skipped 
Modifying data pointer when skipping samples may make it unaligned.
Workaround for Ticket6349.

This should fix the crash of ticket's testcase and a crash/regression
with avxsynth (reported by Michael Niedermayer).

Also change frame->nb_samples < max to frame->nb_samples <= max.
This improves performance. Benchmark:
./ffmpeg -filter_complex "aevalsrc=0:n=1166,firequalizer=fixed=on" -f null null

383057f8e7 lavfi: make ff_framequeue_skip_samples() more useful. 
Instead of just updating statistics and leaving the work to the
call site, have it actually do the work.

Also: skip the samples by updating the frame data pointers
instead of moving the samples. More efficient and avoid writing
into shared frames.
