I'm about to add support for kernel handshake API consumers to send TLS Alerts, so introduce the needed protocol definitions in the new header tls_prot.h. This presages support for Closure alerts. Also, support for alerts is a pre-requite for handling session re-keying, where one peer will signal the need for a re-key by sending a TLS Alert.
