This is a convenience function often needed in class initializers.
It returns the class structure of the immediate parent type of the
class passed in. Since derived classes hold a reference count on
their parent classes as long as they are instantiated, the returned
class will always exist.
This function is essentially equivalent to:
g_type_class_peek (g_type_parent (G_TYPE_FROM_CLASS (g_class)))
