Issue #7502 shows that running nlsat eagerly during final check can block quantifier instantiation.
To give space for quantifier instances we introduce two levels for final check such that nlsat is only applied in the second and final level.
In the underlying realclosure implementation, the interval operations for
{`lower`,`upper`}`_is_`{`inf`,`open`} return `bool` results. Currently these
are cast to `int` when surfacing them to the API. This patch keeps them at
type `bool` through to `Z3_rcf_interval`.

The representation of the zero rcf numeral is nullptr, and the is_rational
and is_rational_function operations are not expecting to be called with
nullptr. But there isn't a way to test for that in the API, other than
checking if Z3_rcf_num_to_string returns "0".
This patch adds a couple conditions so that is_rational and
is_rational_function operations handle zero. Maybe this isn't the desired
change. For instance, the is_zero operation could instead be exposed in the
API and preconditions added to the relevant operations.

#7791 reports on using model values during lex optimization that break soft constraints.
This is an artifact of using optimization where optimal values can be arbitrarily close to a rational.
In a way it is by design, but we give the user now an option to control the starting point for epsilon when converting infinitesimals into rationals.

* chipping away at the new code structure
* comments
* debug infinite recursion and split cubes on existing split atoms that aren't in the cube
* share lemmas, learn from unsat core, try to debug a couple of things, there was a subtle bug that i have a hard time repro'ing
* merge
* fix#7603: race condition in Ctrl-C handling (#7755)
* fix#7603: race condition in Ctrl-C handling
* fix race in cancel_eh
* fix build
* add arithemtic saturation
* add an option to register callback on quantifier instantiation
Suppose a user propagator encodes axioms using quantifiers and uses E-matching for instantiation. If it wants to implement a custom priority scheme or drop some instances based on internal checks it can register a callback with quantifier instantiation
* missing new closure

* resolve bad bug about l2g and g2l translators using wrong global context. add some debug prints
* initial attempt at dynamically switching from greedy to frugal splitting strategy in return_cubes. need to test. also there is some bug where the threads take forever to cancel?
* Update RELEASE_NOTES.md
* resolve bug about not translating managers correctly for the second phase of the greedy cubing, and the frugal fallback
* remove unused square-free check
Signed-off-by: Lev Nachmanson <levnach@hotmail.com>
* add some debug prints and impelement internal polynomial fix
* add some comments and debug m_assumptions_used
* redo greedy->frugal strategy so we don't split on existing cubes in frugal at all (eliminate the incorrect/wasteful step by processing current batch first)
* set up initial scaffolding for sharing clauses between threads and batch manager. needs some reworking/debug still
