* As part of this, removed NodeManager::mkVar() (which created a

  tests, which were using this function.

* Performed some review of parser code (my code review #73).

  + I changed the way exceptions were caught and rethrown in
    src/parser/input.cpp.

  + ParserExceptions weren't being properly constructed (d_line and
    d_column weren't intiialized and could contain junk, leading to

  determined to make node building too slow, we can allocate another
  attribute "AtomicHasBeenComputed" to lazily compute atomicity.

* TheoryImpl<> has gone away.  Theory implementations now derive from
  Theory directly and share a single RegisteredAttr attribute for term
  registration (which shouldn't overlap: every term is "owned" by
  exactly one Theory).  Fixes bug #79.

* Additional atomicity tests in ExprBlack unit test.

* More appropriate whitebox testing for attribute ID assignment
  (AttributeWhite unit test).

* Better (and more correct) assertion checking in NodeBuilderBlack.

* run-regression script now checks exit status against what's provided
  in "% EXIT: " gesture in .cvc input files, and stderr against
  "% EXPECT-ERROR: ".  These can be used to support intended failures.
  Fixes bug #84.  Also add "% EXIT: " gestures to all .cvc regressions
  in repository.

* Solved some "control reaches end of non-void function" warnings in
  src/parser/bounded_token_buffer.cpp by replacing
  "AlwaysAssert(false)" with "Unreachable()" (which is known
  statically to never return normally).

* Regression tests now use the cvc4 binary under
  builds/$(CURRENT_BUILD)/src/main instead of the one in bin/ which
  may not be properly installed yet at that point of the build.
  (Partially fixes bug #46.)

* -fvisibility=hidden is now included by configure.ac instead of each
   Makefile.am, which will make it easier to support platforms
   (e.g. cygwin) that do things a different way.

* TheoryUF code formatting.  (re: my code review bug #64)

PARSER STUFF:

* Other minor changes to the new parser to match coding guidelines,
  add documentation, ....

* Add CFLAGS stuff to configure.ac parser Makefile.ams.  This ensures
  that profiling, coverage, optimization, debugging, and warning
  level options will apply to the new parser as well (which is in C,
  not C++).  This fixes the deprecated warning we were seeing this
  evening.

* Now, if you have ANTLR_HOME set in your environment, you don't need
  to specify --with-antlr-dir to ./configure or have libantlr3c
  installed in standard places.  --with-antlr-dir still overrides
  $ANTLR_HOME, and if the installation in $ANTLR_HOME is missing or
  doesn't work, the standard places are still tried.

* Extend "silent make" to new parser stuff.

* Added src/parser/bounded_token_buffer.{h,cpp} to the list of
  exclusions in contrib/update-copyright.pl and mention them as
  excluded from CVC4 copyright in COPYING.  They are antlr3-derived
  works, covered under a BSD license.

OTHER STUFF:

* expr_manager.h, expr.h, expr_manager.cpp, and expr.cpp are now
  auto-generated by a "mkexpr" script.  This provides the correct
  instantiations of mkConst() for public use, e.g., by the parser.

* Fix doxygen documentation in expr, expr_manager.. closes bug #35

* Node::isAtomic() implemented in a better way, based on theory kinds
  files.  Fixes bug #40.  To support this, a "nonatomic_operator"
  command has been added.  All other "parameterized" or "operator"
  kinds are atomic.

* Added expr_black test

* Remove kind::TRUE and kind::FALSE and make a new CONST_BOOLEAN kind
  that takes a "bool" payload; for example, to make "true" you now do
  nodeManager->mkConst(true).

* Make new "cvc4_public.h" and "cvc4parser_public.h" headers.  Private
  headers should include "cvc4_private.h"
  (resp. "cvc4parser_private.h"), which existed previously.  Public
  headers should include the others.  **No one** should include the
  autoheader #include (which has been renamed "cvc4autoconfig.h")
  directly, and public CVC4 headers can't access its #defines.  This
  is to avoid us having the same distribution problem as libantlr3c.

* Preliminary fixes based on Tim's code review of attributes (bug #61).
  This includes splitting hairy template internals into
  attribute_internals.h, for which another code review ticket will be
  opened.  Bug is still outstanding, but pending further
  refactoring/documentation.

* Some *HashFcns renamed to *HashStrategy to match refactoring done
  elsewhere (done by Chris?) earlier this week.

* Simplified creation of make rules for generated files (expr.cpp,
  expr.h, expr_manager.cpp, expr_manager.h, theoryof_table.h, kind.h,
  metakind.h).

* CVC4::Configuration interface and implementation split (so private
  stuff doesn't leak into public headers).

* Some documentation/code formatting fixes.

* Add required versions of autotools to autogen.sh.

A bag of unrelated fixes to bring trunk more in-line with recent
policy discussion (no dead code, no unimplemented unit tests...), and
other fixes:

* src/expr/node_builder.h: uncomment AndNodeBuilder, OrNodeBuilder,
  PlusNodeBuilder, and MultNodeBuilder.  (These had been dead code for
  awhile.)

* src/expr/node_value.cpp: toString() is much more reasonable now,
  printing S-exprs and using variable names (instead of printing raw
  pointer values).  Next, we'll want to define a pretty-printing
  theory interface and perhaps hook this up to that.

* test/unit/expr/node_black.h: implement testIterator(),
  testToString(), and testToStream().

* test/unit/expr/node_builder_black.h: implement testIterator() and
  testAppend(), and add some code to avoid the warnings on clear() for
  unused NodeBuilders.

* src/expr/node_builder.h: redefine "iterator" to be over Nodes rather
  than over NodeValues.  Doesn't make sense to expose the underlying
  NodeValues.  This shouldn't affect anyone, no one was using
  NodeBuilder iterators.

* fix some comments in source code

Adding --mmap option to use memory-mapped file input, which provides a marginal improvement (<5%) on big benchmarks.

* test/unit/context/context_black.h: Test CDList<>.  In particular,
  test behavior of grow(), which was previously very broken, fixed by
  Tim earlier this afternoon.

* add the notion of a "private header".  Private header files (those
  not intended for distribution) should now #include "cvc4_private.h"
  (or "cvc4parser_private.h" for the parser code).  When not actually
  building libcvc4 (resp. libcvc4parser), or associated unit tests, a
  warning is emitted by the preprocessor.  This should make it easier
  to notice (and disentangle early) any unwanted public/private
  mixing.  Currently the warning identifies a couple places where we
  need to fix things.

* added directory infrastructure for arrays and BV theories.

* the Theory inheritance hierarchy makes some assumptions about the
  way inheritance is done.  These are checked at runtime when
  CVC4_ASSERTIONS is on.  See src/theory/theory.h's TheoryImpl<>
  definition for details.

* src/theory/booleans/theory_bool.h, src/theory/booleans/theory_def.h,
  src/theory/arith/theory_arith.h, src/theory/arith/theory_def.h,
  src/theory/uf/theory_uf.h, src/theory/uf/theory_def.h,
  src/parser/antlr_parser.h: minor code formatting fixes as per
  policy.

* src/theory/uf/theory_uf.cpp: fix for non-debug builds.

* src/util/options.h, src/util/model.h, src/util/result.h,
  src/expr/type.h: make CVC4_PUBLIC.

* src/util/decision_engine.h: no longer CVC4_PUBLIC.

* src/expr/expr_manager.cpp: ExprManager::booleanType() and
  ExprManager::kindType() weren't returning a value ?!  Fixed.

* src/expr/expr_manager.h, src/expr/node_manager.h: ExprManager no
  longer depends on NodeManager (public/private interface mixing).
  ExprManagerScope is an internal implementation detail, and is moved
  to node_manager.h.

* src/expr/node.h: mark gdb debug routines as "used" so that GCC
  always emits code for them (even though its static analysis shows
  they're unused).
