Public interface review items:

* Internal uses of CheckArgument changed to AssertArgument/AlwaysAssertArgument()
* Make util/Assert.h cvc4_private instead of public, so AssertionException and friends are now internal-only
* CheckArgument() throws non-AssertionException
* things outside the core library (parsers, driver) use regular C-style assert,
  or a public exception type.
* auto-generated documentation for Smt options and internal options

Also, a small fix to SMT-LIBv1 QF_ABV and QF_AUFBV definitions, which were nonstandard.
