Weekend work. The main points:
* 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

This is a merge from the "theoryfixes+cdattrhash" branch. The changes

=========================================
THIS COMMIT CHANGES THE THEORY INTERFACE!
=========================================
Theory constructors are expected to take an additional "Valuation*"
parameter that each Theory should send along to the base class
constructor. The base class Theory keeps the Valuation* in a
d_valuation field for use by it and by its derived classes.
Theory::getValue() no longer takes a Valuation* (it is expected
to use d_valuation instead). This allows other theory functions
to take advantage of getValue() for debugging or heuristic
purposes.
TODO BEFORE MERGE TO TRUNK:
****implement BitIterator find() in CDAttrHash<bool>.
Specifically:
* Added QF_BV support for SMT-LIB v2.
* Two adjustments to the theory interface as requested by Tim King:
1. As described above.
2. Theories now have const access to the fact queue through base
class functions facts_begin() and facts_end(); useful for
debugging.
* Added an "Asserted" attribute so that theories can check if something
has been asserted or not (and therefore not propagate it). However, this
has been disabled for now, pending more data on the overhead of it, and
pending discussion at the 3/25/2011 meeting.
* Do not define NDEBUG in MiniSat in assertion-enabled builds (so
that MiniSat asserts are evaluated).
* As a result of the new MiniSat assertions, some --incremental
regressions had to be disabled; also, some bitvectors ?!!
* Bug 71 is resolved by adding a specialization for CDAttrHash<> in the
attribute package.
* Fixes for some warnings flagged by clang.
* System tests have arrived! So far mainly infrastructure for having
system tests, but there is a system test aimed at improving code
coverage of the printer package.
* Minor other adjustments to documentation and coding to be more
conformant to CVC4 policy.
Tests have been performed to demonstrate that these changes have no or
negligible effect on performance. In particular, changing the
CDAttrHash<> doesn't have any real effect on performance or memory right
now, since there is only one context-dependent boolean flag (as soon
as another is added, the effect is noticeable but probably still slight).

fix for bug 254, lemmas were propagating at lower levels, and the conflict clauses asserting literal would overwrite the propagated literal
let's see if i break the build again

Merge from cudd branch. This mostly just adds support for linking
against cudd libraries, the propositional_query class (in util/),
which uses cudd if it's available (and otherwise answers UNKNOWN for
all queries), and the arith theory support for it (currently disabled
per Tim's request, so he can clean it up).
Other changes include:
* contrib/debug-keys - script to print all used keys under Debug(), Trace()
* test/regress/run_regression - minor fix (don't export a variable)
* configure.ac - replace a comment removed by dejan's google perf commit
* some minor copyright/documentation updates, and minor changes to source
text to make 'clang --analyze' happy.

adding support for google performance tools to the build sytem, it can be enabled at configure with
--with-google-perftools
to use it on ubuntu, you need to install packages google-perftools and libgoogle-perftools0
to run the profiling of the heap, you can run it for example with
HEAPPROFILE=/tmp/profile ./builds/bin/cvc4 test/regress/regress0/lemmas/clocksynchro_5clocks.main_invar.base.smt
this will create some files /tmp/profile* that you can then
to get the pdf of the profile you can then run
google-pprof --pdf ./builds/bin/cvc4 /tmp/profile.0001.heap > profile.pdf
or for other options check http://goog-perftools.sourceforge.net/doc/

change to the run_regression script to better manage temporary files; hopefully this will somewhat alleviate the problem with all the junk files in /tmp

Fix to bug 251 (non-spurious warnings in builds) by shifting metakind array by 1 to handle the UNDEFINED_KIND case.

ITE removal in TheoryEngine was not properly handling PARAMETERIZED kinds. Fixed and added bug regression. Thanks Andrew Reynolds for the bug report!
