It can only be used on detached ressource to ensure the value validity.

It also probably fixes deadlock between ressources freeing (vout) and input
through gui.

It is very limited:
 - Uncrypted only
 - No ISO or direct disc device
 - No menu
 - No still frame
 - No angle
 - No out of mux stream (some subtitles use it)

It does:
 - title (MPLS)
 - chapter (mark)
 - correct seek
 - hide invalid ES for a given MPLS

So that we don't break the command line of 0.001% of our users

 when checking if fullscreencontrollers position needs to be
 recalculated. Should fix #2283 (what I understand that ticket)

 Please review and test.
