added.
Sharing is turned on only when Boolean terms are detected during preprocessing. QF_UF problems (and others)
that don't use any Boolean terms won't have BV turned on.

output correct
models for such functions (though they are somewhat ugly at present).
There's still a problem with model extraction, but it's not Boolean terms' fault.
Sometimes checkModel() can report that the model is just fine, but if a user extracts
values with getValue(), they find problems with the model (i.e., it doesn't satisfy some
assertions). This appears to be due to an asymmetry between how checkModel() works and
how Model::getValue() works. I'll open a bugzilla report to discuss this after thinking
some more on it.

Passes simple tests and doesn't break existing functionality.
Still need some work merged in for models.
This version enables BV except for pure arithmetic (since we might otherwise need Boolean term support, which uses BV). Tonight's nightly regression run should tell us if/how that hurts performance.

Also some fixes to parametric datatypes I found, and fixes for a handful of bugs, including some observed with --check-models --incremental on together.

equality engine through the setMasterEqualityEngine method. This is a read-only equality engine, so nothing should be added to it directly. Instead each equality engine that is of interest should have the master equality engine attached to it. To set when to use the master equality engine see TheoryEngine::finishInit().

- Changes the signature of getDeltaValue to throw DeltaRationalException and ModelException
-- DeltaRationalExceptions can occur with non-linear arithmetic computations that cannot be done. (0 + delta) * (1 + delta) is not a DeltaRational.
-- ModelExceptions occur if getDeltaValue() is going to return a value that disagrees with its value in the model (due to non-linear arithmetic)
-- ModelExceptions also occur if getDeltaValue(n) is called on a variable arithmetic has never seen before.
- getEqualityStatus() now wraps and catches both of these exceptions. If either occurs, the equality status is EQUALITY_UNKNOWN. This allows arithmetic to handle terms it has never seen before in getEqualityStatus. This resolves bug 453.
- Removes the dead code rowImplication() entirely.

DeltaRationalException which can be called when an operation on a DeltaRational does not have well formed semantics. This allows for things like multiplying two DeltaRationals, which may or may not result in a DeltaRational.

the equality being split on. Instead of issuing 'x != y implies (x < y or x > y)', the lemma is now '(x <= y or x >= y)'. This resolves bug 450.

* remove from public interface (ExprManager, Type)
* CVC parser reports an unimplemented feature error if used
I didn't want to tear it out completely (from NodeManager, TypeNode,
type-checking, pre-processing, etc.) because that's a lot of hassle
and we'll add it back in after the release anyway. It *does* mean
that CVC4::Predicate is in the public interface, but that it can't be
used for anything (by users).
