If we want to be able to update the output chain when the "sout" is
set/unset during playback, we need a way to hook the callback on the
"sout" variable. Either we put it that variable in the core, either we
put it in the playlist (overloaded with unrelated stuff already) and
in the libvlc mediaplayer. With that second option we may not even
need a callback. They can both know when the "sout" is changed and act
accordingly. Probably call a function that would set b_restart_output
seen in this patch.
