Subject: * class.c (rb_make_metaclass): [new]

* class.c (rb_define_class_id): use rb_make_metaclass(), don't
  call Class#inherited hook.

* class.c (rb_class_inherited): [new]

* class.c (rb_define_class): call Class#inherited hook here.

* class.c (rb_define_class_under): ditto after class path is set.

* class.c (rb_singleton_class): use rb_make_metaclass().

* eval.c (rb_eval): same as rb_define_class_under().

* intern.h: prototypes of rb_make_metaclass() and
  rb_class_inherited().

* object.c (rb_class_s_new): use rb_make_metaclass() and
  rb_class_inherited().

* object.c (Init_Object): use rb_make_metaclass().

* struct.c (make_struct): use rb_class_inherited().
