af_amix: avoid spurious EAGAIN.
...
Input on/off state can change in request_samples(), which can result in
a state where only the first input is active. get_available_samples()
will then return 0, and request_frame() will fail with EAGAIN even
though there is data on the single active input.
Take this into account and check the number of active inputs again after
calling request_samples().

af_amix: return AVERROR(EAGAIN) when request_frame didn't produce output.
...
0 should only be returned when there was at least one output frame.

lavfi: remove 'opaque' parameter from AVFilter.init()
...
It is not used in any filters currently and is inherently evil. If
passing binary data to filters is required in the future, it should be
done with some AVOptions-based system.
