When resolver geting a query with DO bit from a client, the max udp packet size should be checked. Once the size of answer message is bigger the max size, tcp query should be triggered.

Currently the simplest forwarder doesn't check, always treate the max udp packet size of query client is 4096.(see more in ticket#598)
