video: separate screenshot modes

Browse Source 
Use different VOCTRLs for "window" and normal screenshot modes. The
normal one will probably be removed, and replaced by generic code in
vo.c, and this commit is preparation for this. (Doing it the other way
around would be slightly simpler, but I haven't decided yet about the
second one, and touching every VO is needed anyway in order to remove
the unneeded crap. E.g. has_osd has been unused for a long time.)
