Fix multiple division-by-zero conditions in MPEG4 parsing
Several situations arise processing MP4 atoms that lead to undefined behavior
when dividing by zero. Typically this results in a crash (denial of service
condition).
NOTE: In most cases we simply avoid the division, leaving kKeyDuration unset.
It may be more desirable to bail out, as we do in the parseSegmentIndex case.
