API: Fix assignment operators (#2680)

The assignment operators of `Term`, `OpTerm`, and `Sort` currently have
an issue. The operators dereference their `shared_ptr` member and assign
the corresponding member of the other object. This is problematic
because if we have for example two `Term`s pointing to the same `Expr`,
then the assignment changes both `Term`s even though we only assign to
one, which is not what we want (see the unit test in this commit for a
concrete example of the desired behavior). To fix the issue, the
assignment operator should just copy the pointer of the other object.
This happens to be the behavior of the default assignment operator, so
this commit simply removes the overloaded assignment operators.

Testing: I did `make check` with an ASAN build and no errors other than
the one fixed in #2607 were reported.

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.
