Subject: Inductive.{type_of_inductive,type_of_constructor,arities_of_specif}
 changed to accept a mind_specif (a couple mutual_inductive_body *
 one_inductive_body) instead of looking it up in the environment. A version of
 the same functions with the old type is put in Inductiveops (outside the
 kernel).
