8a913981f6 fix #6813 - proofs terms are fragile with respect to simplificiation of not(not(e)). It would be better if proof terms didn't have to track this level of detail, but the legacy proof format assumes strictly checkable proofs. A patch is to fixup terms within the mk_transitivity constructor

08599177d0 fix #6808 
remove bv_eq_axioms as an external option to toggle.
Diseqalities have to be enforced for extensionality.
There are no internal code paths where the option is set to false.
