Subject: player: always use demux_chapter

Instead of defining a separate data structure in the core.

For some odd reason, demux_chapter exported the chapter time in
nano-seconds. Change that to the usual timestamps (rename the field
to make any code relying on this to fail compilation), and also remove
the unused chapter end time.
