Import DTLS fix from upstream OpenSSL 0.9.8 branch:
    
    Fix DTLS fragment bug - out-of-sequence message handling which could
    result in NULL pointer dereference in
    dtls1_process_out_of_seq_message().
    
    Note that this will not get FreeBSD Security Advisory as DTLS is
    experimental in OpenSSL.
    
    Security:	CVE-2009-1387
    Obtained from:	OpenSSL CVS
