Changes between 1.0.1j and 1.0.1k [xx XXX xxxx]
+ *) Do not resume sessions on the server if the negotiated protocol
+ version does not match the session's version. Resuming with a different
+ version, while not strictly forbidden by the RFC, is of questionable
+ sanity and breaks all known clients.
+ [David Benjamin, Emilia Käsper]

*) Tighten handling of the ChangeCipherSpec (CCS) message: reject
early CCS messages during renegotiation. (Note that because
renegotiation is encrypted, this early CCS was not exploitable.)
