Add a hook in TLS_Channel that is called when an alert is received.

Currently has the same behavior in client and server; if we got a
NO_RENEGOTIATION alert, and we appear to be renegotiating, delete the
state if it exists.

Noticed when talking to OpenSSL 0.9.8g which rejects all renegotiation
requests.
