Add commands:
(prefer <formula>)
- will instruct case split queue to assign formula to true.
- prefer commands added within a scope are forgotten after leaving the scope.
(reset-preferences)
- resets asserted preferences. Has to be invoked at base level.
This provides functionality related to MathSAT and based on an ask by Tomáš Kolárik who is integrating the functionality with OpenSMT2
for equations x*y + z = 0,
with x, y, z integer, enforce that x divides z
It is (currently) enabled within Grobner completion
and applied partially to x a variable, z linear, and
only when |z| < |x|.
#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

* 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

* Introduce X-macro-based trace tag definition
- Created trace_tags.def to centralize TRACE tag definitions
- Each tag includes a symbolic name and description
- Set up enum class TraceTag for type-safe usage in TRACE macros
* Add script to generate Markdown documentation from trace_tags.def
- Python script parses trace_tags.def and outputs trace_tags.md
* Refactor TRACE_NEW to prepend TraceTag and pass enum to is_trace_enabled
* trace: improve trace tag handling system with hierarchical tagging
- Introduce hierarchical tag-class structure: enabling a tag class activates all child tags
- Unify TRACE, STRACE, SCTRACE, and CTRACE under enum TraceTag
- Implement initial version of trace_tag.def using X(tag, tag_class, description)
(class names and descriptions to be refined in a future update)
* trace: replace all string-based TRACE tags with enum TraceTag
- Migrated all TRACE, STRACE, SCTRACE, and CTRACE macros to use enum TraceTag values instead of raw string literals
* trace : add cstring header
* trace : Add Markdown documentation generation from trace_tags.def via mk_api_doc.py
* trace : rename macro parameter 'class' to 'tag_class' and remove Unicode comment in trace_tags.h.
* trace : Add TODO comment for future implementation of tag_class activation
* trace : Disable code related to tag_class until implementation is ready (#7663).
