lavu/frame: add a duration field to AVFrame

Browse Source 
The only duration field currently present in AVFrame is pkt_duration,
which is semantically restricted to those frames that are output by
decoders.

Add a new field that stores the frame's duration without regard for how
that frame was produced. Deprecate pkt_duration.
