DTLS rehandshake broken

[Sean Buckheister]

Hi,

DTLS rehandshake does not work in 3.0.13, hasn't in 3.0.12 and 3.0.3,
and probably in every version between those. Instead of performing
rehandshake, the system simply locks.

One possible test, two shells required.

First shell: gnutls-serv --echo --udp --priority NORMAL:+ANON-ECDH

Second shell: gnutls-cli --udp --priority NORMAL:+ANON-ECDH --port 5556
localhost --rehandshake
