        * gparamspecs.[hc]: put newly created param spec types into a
        global array.

        * gboxed.[hc]: moved boxed types with _get_type() function here,
        for: G_TYPE_CLOSURE, G_TYPE_VALUE, G_TYPE_VALUE_ARRAY,
        G_TYPE_GSTRING.

        * gtype.h: removed fundamental branch APIs and derived enum
        values.
