Various fixes on typeclasses:
- Better interface in constrintern w.r.t. evars used during typechecking - Add "unsatisfiable_constraints" exception which gives back the raw evar_map that was not satisfied during typeclass search (presentation could be improved). - Correctly infer the minimal sort for typeclasses declared as definitions (everything was in type before). - Really handle priorities in typeclass eauto: goals produced with higher priority (lowest number) instances are tried before other of lower priority goals, regardless of the number of subgoals. - Change inverse to a notation for flip, now that universe polymorphic definitions are handled correctly. - Add EquivalenceDec class similar to SetoidDec, declaring decision procedures for equivalences. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@10724 85f007b7-540e-0410-9357-904b9bb8a0f7
