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

make it unambiguous for case-insensitive filesystems like on Mac. Fixes Mac builds

* 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.

SmtEngine resolved.
ALL_SUPPORTED and QF_ALL_SUPPORTED logics now supported by SMT-LIB parsers. In SMT-LIBv2, if a (set-logic..) command is missing, ALL_SUPPORTED is assumed, and a warning is issued, as discussed on the cvc4-devel mailing list.

src/theory/logic_info.{h,cpp} contains the CVC4::LogicInfo class, which keeps
track of which theories are active (which should remain constant throughout
the life of an SmtEngine) and other details (like integers, reals,
linear/nonlinear, etc.).
This class has a default constructor which is the most all-inclusive logic.
Alternatively, this class can be constructed from an SMT-LIB logic string
(the empty string gives the same as "QF_SAT"). Once constructed, theories
can be enabled or disabled, quantifiers flipped on and off, integers flipped
on and off, etc. At any point an SMT-LIB-like logic string can be extracted.
The SmtEngine keeps a LogicInfo for itself and shares with the TheoryEngine
(and, in turn, the theories) only a const reference to it. This ensures that
the logic info doesn't mutate over the course of the run.
As part of this commit, the TheoryEngine's old notion of "active theories"
has been completely removed. As a result, SMT benchmarks that are incorrectly
tagged with a logic will assert-fail or worse. (We should probably fail
more gracefully in this case.) One such example was bug303.smt2,
which used UF reasoning but was tagged QF_LIA. This has been fixed.
