Both libavformat and libavcodec requires this function.

This commit also makes sure the extradata and subtitle_header are NUL
terminated, without taking into account the trailing '\0' in account in
the size.

At the same time, it should fix 'warning: dereferencing type-punned
pointer will break strict-aliasing rules' warning for compilers who
don't consider uint8_t** and char** compatibles.

This changes the event_cmp() function to the correct signature,
avoiding an ugly cast.
