demux_lavf: try harder to make up a frame rate
Frame rate information is mostly irrelevant for playback, but it's
needed at least to convert frame numbers used in some subtitle formats
(like MicroDVD) into timestamps. Libavformat stopped making up a frame
rate if no "reliable" information is available (commit 7929e22bd
"lavf: don't guess r_frame_rate from either stream or codec timebase",
1.5 months ago). This caused a regression with AVI files and MicroDVD
subtitles. Add a heuristic similar to what libavformat used to have,
to make up FPS values which should work at least for the AVI+MicroDVD
use case.
