Clean up CHANGES

     whose return value is often ignored. 

     [Steve Henson]

 Changes between 1.0.1j and 1.0.2 [xx XXX xxxx]

   *) 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.)

      [Emilia Käsper]

   *) Tighten client-side session ticket handling during renegotiation:

      ensure that the client only accepts a session ticket if the server sends

      the extension anew in the ServerHello. Previously, a TLS client would

      reuse the old extension state and thus accept a session ticket if one was

      announced in the initial ServerHello.

      Similarly, ensure that the client requires a session ticket if one

      was advertised in the ServerHello. Previously, a TLS client would

      ignore a missing NewSessionTicket message.
