Based on the driver's bson_visitor_t struct, we don't define callbacks for the undefined, DB pointer, and symbol types. We should double check that decoding BSON containing these types throws an exception.
Note: the 1.x driver interprets symbols as strings and attempts to convert DB pointers to a DBRef document. I'd say there's no reason to maintain the old DB pointer conversion logic, especially because it can silently modify a document when round-tripping through the driver. As for symbol/string handling, perhaps we should check if we have any obligation to support them due to DRIVERS-196.
