This commit changes the contrib/get-cryptominisat script to only build

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

CryptoMiniSat binary due to the static version of these libraries not

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.

Returning 0 marks those tests as passed. To make it more clear which
tests were skipped, this commit adds the `SKIP_RETURN_CODE` [0] property
to the regression tests and changes the regression script to return 77
for skipped tests. The feature is supported since at least CMake 3.0 [0].
For backwards compatibility with autotools, returning 77 for skipped
tests is only active when `--cmake` is passed to the run_regression.py
script.
