Added support in tinyDTLS to support rehandshake
As per RFC 6347 section 4.2.8, DTLS Server should support requests
from clients who have silently abandoned the existing association
and initiated a new handshake request by sending a ClientHello.
Code is updated to detect this scenario and delete the old
association when client successfully responds to HelloVerifyRequest.
