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.

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.

Nikolaj Bjorner 81d97a81af enable nested ADT and sequences 
add API to define forward reference to recursively defined datatype.
The forward reference should be used only when passed to constructor declarations that are used in a datatype definition (Z3_mk_datatypes). The call to Z3_mk_datatypes ensures that the forward reference can be resolved with respect to constructors.

Nikolaj Bjorner 87d4ce2659 working on #5614 
there are some different sources for the performance regression illustrated by the example. The mitigations will be enabled separately:
- m_bv_to_propagate is too expensive
- lp_bound_propagator misses equalities in two different ways:
   - it resets row checks after backtracking even though they could still propagate
   - it misses equalities for fixed rows when the fixed constant value does not correspond to a fixed variable.

Andrew V. Jones f1b8376739
Rename 'user' to 'user_solver' #5586 (#5587) 
Issue #5586 reported that Android builds (targetting, e.g., x86) failed
to compile due to a conflict between:

* `struct user` in `sys/user.h`; and
* `namespace user` in z3's `user_solver.h`

This issue is resolved by renaming `namespace user` to `namespace
user_solver` (matching the header name) to avoid this conflict.
