* clutter/clutter-container.[ch]: Add a generic actor container interface, for actors to implement without subclassing ClutterGroup. * clutter/clutter-group.[ch]: Make ClutterGroup implement the ClutterContainer interface, and deprecate the colliding methods. * clutter/clutter-layout.[ch]: Add extended layout interface. Actors and containers requiring or honouring complex layout management should implement this interface and provide at least one of the available layout types: width for height, height for width, natural size, iterative size request. * clutter/clutter-label.c: A ClutterLabel requires height for width layout management, so it implements the ClutterLayout interface. * clutter/Makefile.am: Add new files to the build. * tests/*.c: * examples/*.c: Update tests and examples code to use the new ClutterContainer API instead of ClutterGroup.
