wip - updates to proof logging and self-checking

Browse source 
move self-checking functionality to inside sat/smt so it can be used on-line and not just off-line.

when self-validation fails, use vs, not clause, to check. It allows self-validation without checking and maintaining RUP validation.

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

z3 sat.smt.proof.check=true sat.euf=true /v:1 sat.smt.proof.check_rup=true /st file.smt2 sat.smt.proof=p.smt2
