Avoid clutter segfaulting when used without invoking clutter_init(). This is needed when using api documentation tools and every other tool relying on the GObject introspection API (esp. on a headless box). see the note in clutter/clutter-feature.c:clutter_feature_init for a full explanation. * clutter/clutter-feature.c: Call clutter_feature_init() when needed by one of the accessors of the features structure. * clutter/clutter-main.c: * clutter/clutter-private.h: Remove clutter_feature_init() public declaration: the features support check is done the first time a feature is needed. * clutter/clutter-main.c: Do not ever access the clutter main context pointer directly; instead, obtain a pointer to it via clutter_context_get_default(), which will always return something valid.
