4abff18e8d fill in missing pieces of proof hint checker for Farkas and RUP 
The proof validator based on SMT format proof logs uses RUP to check propositional inferences and has plugins for theory axioms/lemmas.

e0aa32e6c5 fix #6270 
MBQI asserts auxiliary function definitions to handle models of arrays. This is unsound if the definition contains a model value.

63f48f8fd4 add options for logging learned lemmas and theory axioms 
- add solver.axioms2files
  - prints negated theory axioms to files. Each file should be unsat
- add solver.lemmas2console
  - prints lemmas to the console.
- remove option smt.arith.dump_lemmas. It is replaced by solver.axioms2files

09696e989e add missing lambda defs per #5509 
the result is now unknown because the nested expression contains exists, which doesn't get replaced by universal quantifier which is assumed by the legacy core.
The legacy core should not depend on universal quantifiers only, but fixing this is a risk. Workaround is to rewrite goals using forall only (replace exists by de-Morgan dual).

cfd0486582 Catch exceptions by const-reference 
Exceptions caught by value incur needless cost in C++, most of them can
be caught by const-reference, especially as nearly none are actually
used. This could allow compiler generate a slightly more efficient code.

357b4b20fd fix #1365. Filter MBQI instantiations for as-array terms that lead the array theory to return unknown and therefore block further instantiations. as-array terms are at this point almost always created from internal model values so quantifier instantiations with these have little value, other than instantiations of other paraameters that may indepdendently help
