Arie Gurfinkel d06f4bd337 Fix reset of params_ref in solver 
params_ref is not a ref, and params_ref::reset is not ref::reset.

params_ref::reset resets the params object being pointed to by
params_ref.

A proper way to reset a params_ref as a reference is to assign an
empty params_ref object to it.

Arie Gurfinkel 55126692c9 spacer: counterexample to pushing (ctp) 
Enable using fixedpoint.spacer.ctp=true

For each lemma L currently at level k, keep a model M that justifies
why L cannot be pushed to (k+1). L is not pushed while the model M
remains valid.

Arie Gurfinkel 5a6bd5e782 hypothesis_reducer: worked around propositional literals 
propositional formulas (disjunctions) can appear as literals.  This
makes it tricky to recognize whether a formula is a unit clause when
re-building unit resolution.

Added work-around that identifies whether a formula is a literal based
on its appearance in previous unit resolution step.

Arie Gurfinkel 0fe5e6c2a6 Fix handling of complex literals in hypothesis_reducer 
In Z3, an arbitrary, even propositional, formula can be a literal.

This requires careful handling of restructuring of unit resolution.
