Nikolaj Bjorner 26f4d3be20 significant update to Horn routines: add module hnf to extract Horn normal form (removed from rule_manager). Associate proof objects with rules to track (all) rewrites, so that proof traces can be tracked back to original rules after transformations

Leonardo de Moura 3a15db5244 Fix uninterpreted sort definition. There was a mismatch in the behavior of the API and SMT front-ends. The SMT front-ends were using user_sorts to be able to support parametric uninterpreted sorts. After this fix, the API also creates user_sorts.
