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.
