This was a utility class for dynamically changing argc/argv.

Towards disentangling Options / NodeManager / SmtEngine.
This PR removes options --use-theory=NAME and --replay/--replay-log. Both of these options are highly complex, unused, and lead to complications when implementing the way options and our build system work.
The first is motivated by making TheoryEngine use an "alternate" theory, which appears to e.g. make it so that TheoryIdl could entirely replace TheoryArith. I believe this is too heavy handed of a solution: there should a consistent TheoryArith class, and options should be used to enable/disable alternate modules within it.
The second attempts to replay low level decisions from the SAT solver. It is documented as not working (in 1.0). I do not believe this is worth salvaging.
It also removes the solver in src/theory/idl, which cannot be enabled after this commit.

This commit adds support for code generation of options with modes (enums). From now on option enums can be specified in the corresponding *.toml files without the need of extra code. All option enums are now in the options namespace.

This commit adds an option `--strings-process-loop-mode` that allows
finer-grained control over CVC4 processes looping word equation. In
particular, performing normal loop breaking sometimes leads to worse
performance. The "simple" mode disables that inference.

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.

The sources of all previous libraries are now added to libcvc4 and built as
libcvc4. This removes circular dependencies between libcvc4 and libexpr.
Further, we now only have one parser library and don't build additional
libraries for each language.
