Nikolaj Bjorner 5c2c0ae900 force-push on new_eq, new_diseq in user propagator, other fixes to Python bindings for user propagator 
This update allows the python bindings for user-propagator to handle functions that are declared to be registered with the user propagator plugin. It fixes a bug in UserPropagateBase.add to allow registering terms dynamically during search.
It also fixes a bug in theory_user_propagate as scopes were not fully pushed when the solver gets the callbacks for new equalities and new disequalities.
It also adds equality and disequality interfaces to the sat/smt solver version (which isn't being exercised in earnest yet)

Nikolaj Bjorner b68af0c1e5 working on reconciling perf for arithmetic solvers 
this update integrates inferences to smt.arith.solver=6 related to grobner basis computation and handling of div/mod axioms to reconcile performance with smt.arith.solver=2.

The default of smt.arth.nl.grobner_subs_fixed is changed to 1 to make comparison with solver=2 more direct.

The selection of cluster equalities for solver=6 was reconciled with how it is done for solver=2.

Nuno Lopes 73a24ca0a9 remove '#include <iostream>' from headers and from unneeded places 
It's harmful to have iostream everywhere as it injects functions in the compiled files

Nikolaj Bjorner 637120ced5 Treat arguments to recursive functions as beta redexes 
An argument to a recursive function would escape the scope of the function application when the recursive function definitions are unfolded. Therefore, such argument occurrences need not be considered for extensional equality / equality sharing.

This filter is mostly relevant for recursive functions that take a lambda expression as argument. Lambda expressions / arrays that occur in shared occurrences are checked for extensionality.
