Nikolaj Bjorner ab8fe199c5 fix case for 0 multiplier in monomial_bounds 
disabled in master - it violates invariants in the lra solver.

Nikolaj Bjorner adad468cd7 allow copy within a user scope #6827 
this will allow copying the solver state within a scope.
The new solver state has its state at level 0. It is not possible to pop scopes from the new solver (you can still pop scopes from the original solver). The reason for this semantics is the relative difficulty of implementing (getting it right) of a state copy that preserves scopes.

Nikolaj Bjorner c6e3fb446a print lemmas2console faster 
- add option pp.no_lets (default = false) to print formulas without let (used by the low-level SMT2 printer).
- print lemmas2console faster by using the low level printer

Nikolaj Bjorner 6188c536ef add logging of propagations to smt core 
log theory propagations with annotation "smt".
It allows tracking theory propagations (when used in conflicts) in the clause logs similar to the new core.

- add solver.lemmas2console
  - prints lemmas to the console.
- remove option smt.arith.dump_lemmas. It is replaced by solver.axioms2files
