remove DecRefQueue, use Z3_enable_concurrent_dec_ref (#6332) 
The notion of reference counted contexts never worked.
The reference count to a context only ends up being 0 if the GC kicks in and disposes the various z3 objects. A call to Dispose on Context should free up all resources associated with that context. In exchange none of the resources are allowed any other operation than DecRef. The invocations of DecRef are protected by a lock and test on the context that the native pointer associated with the context is non-zero. Dispose sets the native pointer to zero.

Z3_enable_concurrent_dec_ref ensures that:

- calls to decref are thread safe. Other threads can operate on the context without interference.

The Z3_context ensures that
- z3objects allocated, but not disposed during the lifetime of Z3_context are freed when Z3_context is deleted (it triggers a debug warning, but this is now benign).

Nikolaj Bjorner 809838fede solve for fold, expand rewrites under fold/map 
Occurrences of map and fold are interpreted.
They are defined when the seq argument is expanded into a finite
concatenation. The ensure this expansion takes place, each fold/map term
is registered and defined through rewrites when the seq argument simplifies.

Nikolaj Bjorner 53611f47df modify clauses used by not-contains 
The literal "emp" can be true in the current assignment, in which case the clause
cnt or emp or ~postf is true and does not contribute to propagation.
This saves, potentially, for generating lemmas for postf.

Add a lemma a = "" or |s| >= idx when a = tail(s, idx)
The lemma ensures that length bounding on s is enforced
(the branch that expands not-contains for long sequences s is closed).
