Add SmtGlobals Class

- The options replayStream, lemmaInputChannel, lemmaOutputChannel have been removed due to their datatypes. These datatypes were previously pointers to types that were not usable from the options/ library.
- The option replayLog has been removed due to inconsistent memory management.
- SmtGlobals is a class that wraps a pointer to each of these removed options. These can each be set independently.
- There is a single SmtGlobals per SmtEngine with the lifetime of the SmtEngine.
- A pointer to this is freely given to the user of an SmtEngine to parameterize the solver after construction.
- Selected classes have been given a copy of this pointer in their constructors.
- Removed the dependence on Node from Result. Moving Result back into util/.
