CMake: Set RPATH on installed binary (#2671)
Currently, when installing CVC4 with a custom installation directory on
macOS, the resulting binary cannot be executed because the linker cannot
find the required libraries (e.g. our parser). This commit changes our
build system to use the `CMAKE_INSTALL_RPATH` variable to add the
installation directory to the RPATH list in the exectuable.

Instantiating any object crashes python. Since swig3.0.8 is currently the apt-get install for Ubuntu 16.04, I thought it'd be good to have a check for that. If python3 is preferred and the swig version is 3.0.8, it errors out and asks users to downgrade or upgrade SWIG.

CMake: Set PORTFOLIO_BUILD when building pcvc4 (#2666)
Back when we used Autotools, we set the PORTFOLIO_BUILD macro when
building pcvc4. Our CMake build system is currently not doing that, so
setting thread options when running pcvc4 results in an error message
saying that "thread options cannot be used with sequential CVC4."
This commit fixes that behavior by recompiling driver_unified.cpp with
different options for the cvc4 and the pcvc4 binary.

Only build CryptoMiniSat library, no binary (#2657)
This commit changes the contrib/get-cryptominisat script to only build
the CryptoMiniSat library instead of both the library and the binary.
The advantage of this is that we can compile a static version of the
CryptoMiniSat library without having a static version of glibc or
libstdc++ (this is fine as long as we do a shared library build of
CVC4). This is an issue on Fedora (tested on version 25) where the
contrib/get-cryptominisat script was failing when building the
CryptoMiniSat binary due to the static version of these libraries not
being available. Since we just want to build the library, the commit
also changes the script to not install CryptoMiniSat anymore and updates
the CMake find script to accomodate the new folder structure. Side note:
the folder structure generated after this commit is a bit more uniform
with, e.g. the CaDiCaL script: The source files are directly in the
cryptominisat5 folder, not in a subfolder.

the `ModalException` thrown in this case into a

Add OptionException handling during initialization (#2466)
The initial motivation for this commit was that dump with an invalid tag
was leading to a segfault. The reason for the segfault was as follows:
1. `api::Solver` creates an `ExprManager`, which is stored in a
`unique_ptr` as a class member
2. The `api::Solver` tries to create an SmtEngine instance
3. The `SmtEnginePrivate` constructor subscribes to events in the
NodeManager and starts registering option listeners
4. When the `SmtEnginePrivate` gets to registerSetDumpModeListener, it
registers and notifies the DumpModeListener which calls
Dump::setDumpFromString, which fails with an `OptionException` due to
the invalid tag
5. While propagating the exception through `api::Solver`, the
`ExprManager` is deleted but the non-existent `SmtEnginePrivate` is
still subscribed to its events and there are still option listeners
registered. This leads to a segfault because the NodeManager tries to
notify the `SmtEnginePrivate` about deleted nodes
This commit fixes the issue by catching the `OptionException` in
`SmtEnginePrivate`, unsubscribing the `SmtEnginePrivate` from the
NodeManager events and deleting its option listener registrations before
rethrowing the exception. In addition, it changes the
`Options::registerAndNotify()` method to immediately delete a
registration if notifying the registration resulted in an
``OptionException`` (otherwise only the `ListenerCollection` knows about
the registration and complains about it in its destructor). Finally,
the commit adds a simple regression test for invalid dump tags.

Fix string register extended terms (#2597)
A regress2 benchmark was failing, due to a recent change in our strings rewriter.
The issue is that our string rewriter is now powerful enough to deduce that certain extended terms like `(str.substr (str.++ x "zb") 1 1)` must be non-empty. As a consequence, our emptiness-split `(str.substr (str.++ x "zb") 1 1) = "" OR len( (str.substr (str.++ x "zb") 1 1) ) > 0` is instead a propagation `len( (str.substr (str.++ x "zb") 1 1) ) > 0`. This means that `(str.substr (str.++ x "zb") 1 1)` may not appear in an assertion sent to strings.
The fix is to ensure that extended function terms in any assertions *or shared terms* are registered.
This also simplifies the code so that another (now spurious) call to ExtTheory::registerTermRec is removed.

Fix "catching polymorphic type by value" warnings (#2556)
When using the `TS_ASSERT_THROWS` marco from CxxTest, we have to make
sure that we use a reference type for the exception, otherwise the unit
test tries to catch the exception by value, resulting in "catching
polymorphic type by value" warnings.

Fix dumping pre/post preprocessing passes (#2469)
This commit changes the hard-coded list of checks for
preprocessing-related dump tags to take advantage of the new
preprocessing pass registration mechanism from PR #2468. It also fixes a
typo in the `Dump.isOn()` check in `PreprocessingPass::dumpAssertions()`
and adds a list of available passes to the `--dump help` output.

Refactor preprocessing pass registration (#2468)
This commit refactors how preprocessing pass registration works,
inspired by LLVM's approach [0]. The basic idea is that every
preprocessing pass declares a static variable of type `RegisterPass` in
its source file that registers the pass with the
`PreprocessingPassRegistry` when starting the program. The registry is a
singleton that keeps track of all the available passes and allows other
code to create instances of the passes (note: previously the registry
itself was owning the passes but this is no longer the case). One of the
advantages of this solution is that we have a list of available passes
directly at the beginning of the program, which is useful for example
when parsing options.
As a side effect, this commit also fixes the SortInference pass, which
was expecting arguments other than the preprocessing pass context in its
constructor.
This commit is required for fixing dumping pre/post preprocessing
passes. It is also the ground work for allowing the user to specify a
preprocessing pipeline using command-line arguments.
