Summary: Replace dynamic_cast<> so that users can choose to build with RTTI off, so that they can save several bytes per object, and get tiny more memory available. Some nontrivial changes: 1. Add Comparator::GetRootComparator() to get around the internal comparator hack 2. Add the two experiemental functions to DB 3. Add TableFactory::GetOptionString() to avoid unnecessary casting to get the option string 4. Since 3 is done, move the parsing option functions for table factory to table factory files too, to be symmetric.
