Options merge. This commit:
1. changes the way options are declared (see http://church.cims.nyu.edu/wiki/Options)
2. moves module-specific options enumerations (SimplificationMode, DecisionMode, ArithUnateLemmaMode, etc.) to their own header files, also they are no longer inside the Options:: class namespace.
3. includes many SMT-LIBv2 compliance fixes, especially to (set-option..) and (get-option..)
The biggest syntactical changes (outside of adding new options) you'll notice are in accessing and setting options:
* to access an option, write (e.g.) options::unconstrainedSimp() instead of Options::current()->unconstrainedSimp.
* to determine if an option value was set by the user, check (e.g.) options::unconstrainedSimp.wasSetByUser().
* ensure that you have the option available (you have to #include the right module's options.h file, e.g. #include "theory/uf/options.h" for UF options)
*** this point is important. If you access an option and it tells you the option doesn't exist, you aren't #including the appropriate options.h header file ***
Note that if you want an option to be directly set (i.e., other than via command-line parsing or SmtEngine::setOption()), you need to mark the option :read-write in its options file (otherwise it's read-only), and you then write (e.g.) options::unconstrainedSimp.set(true).
Adding new options is incredibly simple for primitive types (int, unsigned, bool, string, double). For option settings that you need to turn into a member of an enumerated type, you write a custom "handler" for the option---this is no additional work than it was before, and there are many examples to copy from (a good one is stringToSimplificationMode() in src/smt/options_handlers.h).
Benefits of the new options system include:
1. changes to options declarations don't require a full-source rebuild (you only have to rebuild those sources that depend on the set of options that changed).
2. lots of sanity checks (that the same option isn't declared twice, that option values are in range for their type, that all options are documented properly, etc.)
3. consistency: Boolean-valued option --foo gets a --no-foo automatically, documentation is generated consistently, the option-parsing matches the documented option name, etc.
4. setting options programmatically via SmtEngine::setOption() is enabled, and behaves the same as command-line equivalents (including checking the value is in range, etc.)
5. the notion of options being "set by the user" is now primitive; you can use (e.g.) options::unconstrainedSimp.wasSetByUser() instead of having to use (and maintain) a separate Boolean option for the purpose
I've taken lots of care not to break anything. Hopefully, I've succeeded in that.

Basically, this involves creating a separate StatisticsRegistry for the

separating out the expr statistics into a separate registry is probably

Bugs resolved by this commit: #314, #322, #359, #364, #365.
See below for details.
* Fix the "assert" name-collision bug (resolves bug #364).
Our identifiers should never be named "assert", as that's a preprocessor
definition in <assert.h>, which is often #included indirectly (so simply
having a policy of not including <assert.h> isn't good enough---one of
our dependences might include it). It was once the case that we didn't
have anything named "assert", but "assert()" has now crept back in.
Instead, name things "assertFoo()" or similar. Thanks to Tim for the
report.
To fix this, I've changed some of Dejan's circuit-propagator code from
"assert()" to "assertTrue()". Ditto for Andy's explanation manager.
Guys, if you prefer a different name in your code, please change it.
* Fix the incorrect parsing of lets in SMT-LIBv2 parser (resolves bug #365).
Inner lets now shadow outer lets (previously, they incorrectly gave an
error). Additionally, while looking at this, I found that a sequential let
was implemented rather than a parallel let. This is now fixed. Thanks to
Liana for the report.
* Remove ANTLR parser generation warnings in CVC parser (resolves bug #314).
* There were a lot of Debug lines in bitvectors that had embedded toString()
calls. This wasted a LOT of time in debug builds for BV benchmarks
(like in "make regress"). Added if(Debug.isOn(...)) guards; much faster
now.
* Support for building public-facing interface documentation only (as opposed
to all internals documentation). Now "make doc" does the public-facing and
"make doc-internals" does documentation of everything. (Along with changes
to the nightly build script---which will now build and publish both types
of Doxygen documentation---this resolves bug #359).
* Fix the lambda typechecking bug (resolves bug #322). Thanks to Andy for the
report (a long long time ago--sorry).
* The default output language for all streams is now based on the current set
of Options (if there is one). This has been a constant annoyance, especially
when stringstreams are used to construct output. However, it doesn't work
for calls from outside the library, so it's mainly an annoyance-fixer for
CVC4 library code itself.
* Add some CVC4_UNUSED markers to local variables in theory_arith.cpp that
are used only in assertions-enabled builds (and thus give warnings in
production builds). This was briefly discussed at the meeting this week.

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.

Bug fix in justification heuristic. Had to do with how
a "visited" node in the recursive findSplitter method was
handled (which would lead to infinite loop). Earlier,
they were ignored assuming the ancestor would split on it
later. The right thing to do is to split on it right away.
(Fixes errors from the fuzzer, not the ones from last night's
regression)

Fix for incompleteness bug with decision engine: repeated simplification
could introduce additional assertions that were not beign processed by the
decision engine. Now these assertions are merged in with pre-ITE-removal
assertions, ensuring the decision engine sees them.
