This is an attempt to fix the bug in the justification heuristic. The
other minor change is removing dependency of header file in
theory_engine.h

It fixes all known wrong answers in QF_BV and QF_AUFBV. It doesn't fix a
wrong answer for QF_AUFLIA -- it is currently unclear what is the cause
of this bug, could be sharing.

Performance impact (turns out) is none on QF_BV and QF_AUFBV (except, of
course, those for which the answer was wrong earlier; and also perhaps
one or two off-cases)

The issue was with how the infinite loop in justification stuff was prevented.
To keep it short, I skip what was wrong earlier, and this is what is done
now:
* whenever an atomic formula is seen, a list of pairs of <IteSkolemVariable,
  AssertionCorrespondingToIteSkolem> is created for each skolem occuring in
  the atom.
* we iterate over this list, doing the following: check if skolem is marked
  as visited. if not, mark visited, recurse, when back unmark.

I lied, I will tell you what was being done earlier was -- 1. the check for
not being visited was being done in each recursive call, not just for atoms.
2. The AssertionCorrespondingToIteSkolem was being used to check if something
is visited and not IteSkolemVariable. I don't know if this makes any
difference, but anyhow, I think this is cleaner & clearer, so I keep this.

Don't use the "inlined" feature of ANTLR 3.2, which causes a buffer overflow condition when reading from stdin.  This should completely resolve bug #319.

However, on large inputs especially (like the stp/testcase benchmarks), this inlining feature can speed parsing by 5-10%, at the cost of not supporting interactive sessions on stdin (like in the SMT-COMP application track).
So I updated the submission script and competition build so that
* a competition build with antlr-inlining is built for the main and parallel tracks
* a competition build without antlr-inlining is built for the application track

Again, the effect is only when reading the stdin stream (but that's how SMT-COMP works).  For normal (non-competition) builds, we need to support interactive sessions (from e.g. KIND) on stdin, so this inlining is off for all builds except main- and parallel-track competition builds.

Also added a "get-antlr-3.4" script that automatically downloads and locally installs a copy of libantlr3c and the antlr parser generator inside the CVC4 source tree.

Closing bug #319.
