Nikolaj Bjorner e0945f57bb fix #7554 
mbp_qel  uses two iterations of saturation.
The first iteration uses only congruences, not the model.
The second iteration uses the model.
Terms are marked as "seen" during either iteration and will not be reprocessed if they are "seen".
All select terms get marked as "seen" to avoid reproducing Ackerman axioms.
But this conflicts with expanding select-store axioms during
the phase of saturation where use_model is allowed.

Nikolaj Bjorner f8f26788ad convert def into expression tree 
prior data-structure could not represent
((1 + x) div 2) * 2
It is possible to have nested expressions with div.
To deal with this, replace original def by an expression tree data-structure.

Nikolaj Bjorner 50f9fddfd2 Add unification based projection function 
Heuristic for EMBPR is to unify terms that occur in uninterpreted contents. Walk partitions that are pure f(t) and an impure f(s)
and attempt to unify t with s ensuring that merges from s preserves satisfiability.

Nikolaj Bjorner eee96ec312 bug fixes and cleanup in projection functions 
spacer would drop variables of sorts not handled by main loop.
- projection with witness needs to disable qel style preprocessing to ensure witnesses are returned.
- add euf plugin to handle uninterpreted sorts (and then uninterpreted functions)
