- Splitting the two instances of CheckArgument. The template version is now always defined in base/exception.h and is available in a cvc4_public header. This version has lost its variadic version (due to swig not supporting va_list's). The CPP macro version has been renamed PrettyCheckArgument. (Taking suggestions for a better name.) This is now only defined in base/cvc4_assert.h. Only use this in cvc4_private headers and in .cpp files that can use cvc4_private headers. To use a variadic version of CheckArguments, outside of this scope, you need to duplicate this macro locally. See cvc3_compat.cpp for an example.
- Making fitsSignedInt() and fitsUnsignedInt() work more robustly for CLN on 32 bit systems.
- Refactoring ArrayStoreAll to avoid potential problems with circular header inclusions.
- Changing some headers to use iosfwd when possible.

just the header comments at the top, though. Don't update to this rev if
you don't have time for a complete rebuild, and exclude this rev if you
want to see what's new across a range of commits.
(this commit was certified error- and warning-free by the test-and-commit script.)

Replace all cardinality comparison functions <=, ==, !=, >=, <, >, with a single compare() function that can return UNKNOWN in the case of unknown (or large-finite and thus not *precisely* known) cardinalities.

* with a patched SWIG, the ocaml bindings build correctly.
** I will provide my patch to the SWIG dev team.
* fixed some class interfaces to play more nicely with SWIG.
* php, perl, tcl now work; examples added.
* improved binding module building and installation.
Also:
Stop #defining NULL ((void*) 0). This has been in cvc4_public.h for
a long, long time, I forget why I added it in the first place, and
it's a very, very bad idea. In C++, certain things are permitted
for NULL that aren't permitted for ((void*) 0), like for instance
implicit conversion to any pointer type. We didn't see an issue
here (until now, when interfacing with SWIG), because GCC is usually
pretty smart at working around such a broken #definition of NULL.
But that's fragile.
New exception-free Command architecture. Previously, some command
invocations were wrapped in a try {} catch() {} and printed out an
error. This is much more consistent now. Each Command invocation
results in a CommandStatus. The status can be "unsupported",
"error", or "success" (these are each derived classes, though, not
strings, so that they can be easily printed in a language-specific
way... e.g., in SMT-LIBv2, they are printed in a manner consistent
with the spec, and "success" is not printed if the print-success
option is off.) All Command functionality are now no-throw
functions, which @cconway reports is a Good Thing for Google
(where all C++ exceptions are suspect), and also I think is much
cleaner than the old way in this instance.
Added an --smtlib2 option that enables an "SMT-LIBv2 compliance
mode"---really it just sets a few other options like strictParsing,
inputLanguage, and printSuccess. In the future we might put other
options into a compliance mode, or we might choose to make it the
default.

branch)
* add Theory::isSharedTermFact() -- it currently always returns false,
pending theory combination work
* Add "unknown" cardinalities to Cardinality class
* Fix run_regression script to handle CRLF line terminators on Macs
(where sed is non-GNU)
* Convert CRLF line terminators in datatypes regressions to LF

* Type::getCardinality() returns the cardinality for for all types.
Theories give a cardinality in the their kinds file. For
cardinalities that depend on a type argument, a "cardinality
computer" function is named in the kinds file, which takes a
TypeNode and returns its cardinality.
* There's a bitmap for the set of "active theories" in the
TheoryEngine. Theories become "active" when a term that is owned by
them, or whose type is owned by them, is pre-registered (run CVC4
with --verbose to see theory activation). Non-active theories don't
get any calls for check() or propagate() or anything, and if we're
running in single-theory mode, the shared term manager doesn't have
to get involved. This is really important for get() performance
(which can only skimp on walking the entire sub-DAG only if the
theory doesn't require it AND the shared term manager doesn't
require it).
* TheoryEngine now does not call presolve(), registerTerm(),
notifyRestart(), etc., on a Theory if that theory doesn't declare
that property in its kinds file. To avoid coding errors,
mktheorytraits greps the theory header and gives warnings if:
+ the theory appears to declare one of the functions (check,
propagate, etc.) that isn't listed among its kinds file properties
(but probably should be)
+ the theory appears NOT to declare one of the functions listed in
its kinds file properties
* some bounded token stream work
