Fix DTLS session ticket renewal
A DTLS client will abort a handshake if the server attempts to renew the session ticket. This is caused by a state machine discrepancy between DTLS and TLS discovered during the state machine rewrite work. The bug can be demonstrated as follows: Start a DTLS s_server instance: openssl s_server -dtls Start a client and obtain a session but no ticket: openssl s_client -dtls -sess_out session.pem -no_ticket Now start a client reusing the session, but allow a ticket: openssl s_client -dtls -sess_in session.pem The client will abort the handshake.
