Nikolaj Bjorner 7eee7914bd align format of quantifier instantiation with new core 
So far the format is

(forall ((x Int)) body) (not (body[t/x]))

The alternative could be the clause

(not (forall ((x Int)) body)) body[t/x]

they just better be consistent between engines

Nikolaj Bjorner ac1552d194 wip - updates to proof logging and self-checking 
move self-checking functionality to inside sat/smt so it can be used on-line and not just off-line.

new options sat.smt.proof.check_rup, sat.smt.proof.check for online validation.
