This commit reverses an "SZS ontology compliance hack" that was
done for CASC-24 this year, and adds a TPTP pretty-printer which
is capable of outputting results in the TPTP way (rather than the
SMT way).
This commit includes minor changes to the Expr package to add
obvious missing functionality, and to fix the way expressions
with builtin operators are made. These changes are truly a
_fix_, the implementation had not been properly aligned with
the design vision for some corner cases.

users' space.
Specifically, output.h was moved to CVC4's "private-library" rules, which means that it's
not installed on users' machines, and public headers should not include it.
Thanks to Alex Horn for raising the issue on the CVC-BUGS mailing list.

Previously, SMT-LIB logics were treated specially, as in SMT-LIB v1.2.
This led to inconsistencies---such as nonstandard logics like "QF_LIRA"
being accepted in set-logic but not providing the "Real" sort. Now,
the LogicInfo is used and queried, so nonstandard logics should work
fine and declare the correct symbols. SMT-LIB v1.2, unfortunately,
can't take advantage of this fully since symbols like "Array" have
substantially different meanings in different logics.

None of these are enabled by default, so any performance impact
counts as a bug
Options added are:
--decision-threshold=N :default 0
+ ignore all nodes greater than threshold in first attempt to pick decision
--decision-use-weight bool :default false
+ use the weight nodes (locally, by looking at children) to direct recursive search
--decision-random-weight=N int :default 0
+ assign random weights to nodes between 0 and N-1 (0: disable)
--decision-weight-internal=HOW
+ computer weights of internal nodes using children: off, max, sum, usr1 (meaning evolving)

decision: option to auto compute weight of boolean structure

decision: fix design to do partial explorations
* make findSplitterRec and all related helper functions' return
type trivalued, to be able to distinguish between
"partial exploration" vs "done exploration but found nothing"
* keep additional data structure to remember to what extent the
partial exploration has been completed so not to repeat it. we
can use this to make multiple passes on formula with arbritrary
order of thresholds for exploration
