Uoti Urpala 58497380e5 Initial ordered chapters support
Add basic support for Matroska ordered chapters. The switching between
segments is implemented as a general edit timeline that could also be
used for other purposes.

Some things still need improvement. In particular the current code
does not try to do any proper mapping between audio/video/subtitle
streams of different files and there should be options for better
control of how MPlayer searches other files for the required content.
