core: ordered chapters: add heuristic for merging inaccurate chapters

Some Matroska files have inaccurate ordered chapter endpoints, and so
parts where one chapter should end and the next begin at the same
timestamp were not merged. This resulted in an unnecessary seek over a
minimal distance. Add a heuristic to merge parts with a minimal gap or
overlap between them.

Based on patch by Hector Martin <hector@marcansoft.com>.
