    ssl-utils: ensure that the cipher suite matches decoder

    When the cipher suite for the current decryption session is changed via
    a Server Hello, it should not change the cipher suite field of the
    decoder. Otherwise there is a mismatch between the cipher suite and the
    capabilities of the decoder.

    Fix this issue by making the decoder hold a pointer to the (constant)
    SslCipherSuite structure rather than making a copy (and have the decoder
    point to that data).

    I also considered resetting the decoder once the cipher suite changes in
    the Server Hello, but that breaks renegotiation.
