ac1552d194 wip - updates to proof logging and self-checking 
move self-checking functionality to inside sat/smt so it can be used on-line and not just off-line.

when self-validation fails, use vs, not clause, to check. It allows self-validation without checking and maintaining RUP validation.

new options sat.smt.proof.check_rup, sat.smt.proof.check for online validation.

z3 sat.smt.proof.check=true sat.euf=true /v:1 sat.smt.proof.check_rup=true /st file.smt2 sat.smt.proof=p.smt2

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.

bugs in:
- rewriting of 0-ary expressions was incomplete
- sharing annotations when a node has two theories attached it is shared
- sharing of const of an array

Remove unreadable part of pretty printer for lp solver.

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).

d5c6abe14d #close 5363 
Force in-lining auxiliary functions so that model values can be used by SPACER to retrieve counter-examples. This fixes the issue of terminating without a trace. It does not address inefficiency involved with invoking satisfiability checks to retrieve models during trace construction.
