    This rewrite is beneficial, for instance, when bit-vectors are constrained to have many high-level bits set to 0.

Nikolaj Bjorner 1d87592b13 fixes to mod/div elimination 
elimination of mod/div should be applied to all occurrences of x under mod/div at the same time. It affects performance and termination to perform elimination on each occurrence since substituting in two new variables for eliminated x doubles the number of variables under other occurrences.

Also generalize inequality resolution to use div.

The new features are still disabled.

Nikolaj Bjorner 03385bf78d improve quantifier elimination for arithmetic 
This update changes the handling of mod and adds support for nested div terms.

Simple use cases that are handled using small results are given below.

```
(declare-const x Int)
(declare-const y Int)
(declare-const z Int)
(assert (exists ((x Int)) (and (<= y (* 10 x)) (<= (* 10 x) z))))
(apply qe2)
(reset)

(declare-const y Int)
(assert (exists ((x Int)) (and (> x 0) (= (div x 41) y))))
(apply qe2)
(reset)

(declare-const y Int)
(assert (exists ((x Int)) (= (mod x 41) y)))
(apply qe2)
(reset)
```

The main idea is to introduce definition rows for mod/div terms.
Elimination of variables under mod/div is defined by rewriting the variable to multiples of the mod/divisior and remainder.

The functionality is disabled in this push.

Arie Gurfinkel a9b7348b4b (cmake): fix visibility on shell z3 binary 
Commit #b361226 changed symbol visibility from a global to a local option.
This creates inconsistency for shell that is compiled as an executable rather
than as z3 component.

This commit adds same local options to shell target in cmake.

Prior to the fix, clang on OSX complains with lots of warnings about symbol visibility
being different in different translation units that are linked together

This was only being enabled on Windows, Linux, and FreeBSD. (FreeBSD

or later and more recent compilers, this should work everywhere
that threading does, so only disable it within a `SINGLE_THREAD`
build.

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)

Add Z3_enable_concurrent_dec_ref to the API.
It is enables behavior of dec_ref functions that are exposed over the API to work with concurrent GC. The API calls to dec_ref are queued and processed in the main thread where context operations take place (in a way that is assumed thread safe as context operations are only allowed to be serialized on one thread at a time).

Nikolaj Bjorner 316ed778e0 Tune Grobner equations 
\brief convert p == 0 into a solved form v == r, such that
   v has bounds [lo, oo) iff r has bounds [lo', oo)
   v has bounds (oo,hi]  iff r has bounds (oo,hi']

   The solved form allows the Grobner solver identify more bounds conflicts.
   A bad leading term can miss bounds conflicts.
   For example for x + y + z == 0 where x, y : [0, oo) and z : (oo,0]
   we prefer to solve z == -x - y instead of x == -z - y
   because the solution -z - y has neither an upper, nor a lower bound.

The Grobner solver is augmented with a notion of a substitution that is applied before the solver is run.

Nikolaj Bjorner f33c933241 Add substitution routine to pdd

parallel-tactic: fix deadlocking race between shutdown and get_task (#6152) 
Deadlock/Race is as follows:
  1. get_task() reads m_shutdown == false and enters loop body
  2. shutdown() is called; sets m_shutdown = true
  3. shutdown() calls m_cond.notify_all()
  4. get_task() finds no task in try_get_task()
  5. get_task() calls m_cond.wait(), missing the notification
  6. solve() waits forever on join()

Provided patch wraps (2) and (3) with the condition variable lock so that
step (5) cannot miss the notification.

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 815518dc02 add facility for incremental parsing #6123 
Adding new API object to maintain state between calls to parser.
The state is incremental: all declarations of sorts and functions are valid in the next parse. The parser produces an ast-vector of assertions that are parsed in the current calls.

The following is a unit test:

```
from z3 import *

pc = ParserContext()

A = DeclareSort('A')

pc.add_sort(A)
print(pc.from_string("(declare-const x A) (declare-const y A) (assert (= x y))"))
print(pc.from_string("(declare-const z A) (assert (= x z))"))

print(parse_smt2_string("(declare-const x Int) (declare-const y Int) (assert (= x y))"))

s = Solver()
s.from_string("(declare-sort A)")
s.from_string("(declare-const x A)")
s.from_string("(declare-const y A)")
s.from_string("(assert (= x y))")
print(s.assertions())
s.from_string("(declare-const z A)")
print(s.assertions())
s.from_string("(assert (= x z))")
print(s.assertions())
```

It produces results of the form

```
[x == y]
[x == z]
[x == y]
[x == y]
[x == y]
[x == y, x == z]
```
Thus, the set of assertions returned by a parse call is just the set of assertions added.
The solver maintains state between parser calls so that declarations made in a previous call are still available when declaring the constant 'z'.
The same holds for the parser_context_from_string function: function and sort declarations either added externally or declared using SMTLIB2 command line format as strings are valid for later calls.

Nikolaj Bjorner 202ce1edf0 #6100 - two perf fixes 
remaining perf bug is dealing with very large bit-widths. mod 2^n should be computed natively based on n instead of 2^n because we pre-populate an array with all values up to n. Suppose n is 10000, the array has size 10000.

Nikolaj Bjorner d792d30e88 Update NativeContext.cs 
TraceToFile does not correspond to the functionality of enable_trace. Z3_enable_trace tags a trace tag as input. It can be invoked multiple times with different tags. The debug tracing then shows logs with the corresponding tags.

Nikolaj Bjorner 911134b3c7 add new heuristic rc2bin (to be tested) to maxsat 
The rc2bin heuristic is a hybrid of rc2 and binary maxres.
It follows the suggestion by Nina to use rc2 on large cores after a single maxres relaxation step; otherwise maxres (binary) on smaller cores. In the design space of possible hybrids, this variant chooses to always apply a single layer of maxres and then rc2 for large cores.

Nikolaj Bjorner 477e9625ef Don't reset the cache between applications of replace 
tactic/lia2card shows a huge slowdown because the same replace function is called on thousands of assertions. Each time the cache gets reset with thousands of entries - they are all the same.
So don't reset the cache just because... Instead reset the cache if m_refs grows large.

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.

Sparse matrix kernel (#6035) 
* Subtle bug in kernel computation

Coefficient was being passed by reference and, therefore, was
being changed indirectly.

In the process, updated the code to be more generic to avoid rational
computation in the middle of matrix manipulation.

* sparse_matrix: fixed handling of 0 in add_var() and add()

particularly in add_var(), without the fix the user is responsible for checking
coefficients for 0.

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.
