Experimental native MySQL driver

No testing has been performed yet, but changes are extensive enough to
warrant a commit. Of particular note:

- SQL states are enumerated in a separate trait to reduce duplication
- PDOStatement is now an abstract class to avoid duplication of
engine-specific error handling
- Error handling has been cleaned up somewhat
