actor: Add ActorMeta, a base class for actor modifiers ClutterActorMeta is a base, abstract class that can be used to derive classes that are attached to a ClutterActor instance in order to modify the way an actor is painted, sized/positioned or responds to events. A typed container for ActorMeta instances is also provided to the sub-classes can be attached to an Actor.

clutter-actor-meta: Add an internal 'priority' property This adds a priority property to all ClutterActorMetas. The ClutterMetaGroup keeps the list sorted so that higher priority metas remain at the beginning of the list. The priority is a signed integer with the default as zero. An actor meta can therefore be put before all default metas with a positive number, or after with a negative number. There are constants to set an 'internal' priority. The intention is that applications wouldn't be allowed to use these values so that we can keep special internal metas to that are before or after all application metas. The property isn't a real GObject property because for now it is completely internal and only used to implement the 'transparency' property of ClutterActor. ClutterMetaGroup doesn't currently resort the list if the property changes so if we wanted to make it public we should either make it construct-only or make the meta group listen for changes on the property and resort accordingly. The methods in ClutterActor that get the list of metas now use a new function that filters out internal metas from the meta group. Similarly for clearing the metas, the internal metas are left in.

GType _clutter_meta_group_get_type (void) G_GNUC_CONST;
Eliminate G_CONST_RETURN The G_CONST_RETURN define in GLib is, and has always been, a bit fuzzy. We always used it to conform to the platform, at least for public-facing API. At first I assumed it has something to do with brain-damaged compilers or with weird platforms where const was not really supported; sadly, it's something much, much worse: it's a define that can be toggled at compile-time to remove const from the signature of public API. This is a truly terrifying feature that I assume was added in the past century, and whose inception clearly had something to do with massive doses of absynthe and opium — because any other explanation would make the existence of such a feature even worse than assuming drugs had anything to do with it. Anyway, and pleasing the gods, this dubious feature is being removed/deprecated in GLib; see bug: https://bugzilla.gnome.org/show_bug.cgi?id=644611 Before deprecation, though, we should just remove its usage from the whole API. We should especially remove its usage from Cally's internals, since there it never made sense in the first place.
