For the chronicles, I implemented this mainly because I wanted to use
this function in the settb filter, and av_parse_video_frame() is
suited for parsing a *framerate* rather than a generic fraction (also
it lacked validity checks).

Also I'm not sure lavcore is the right place for it, since it's not
multimedia-related then it could stay in lavu as well (avstring.h?,
