Rewrite legacy DTLS unexpected handshake message handling.

Rewrite the code that handles unexpected handshake messages in the legacy
DTLS stack. Parse the DTLS message header up front, then process it based
on the message type. Overall the code should be more strict and we should
reject various invalid messages that would have previously been accepted.
