Ticket 48798 - Enable DS to offer weaker DH params in NSS
    
    Bug Description:  Java is unable to handle DH param's greater than 1024 bit.
    As of NSS 2.20 and higher, nss defaults to params of 2048 bit. This breaks
    all java clients.
    
    Fix Description:  This adds a new option, allowWeakDHParams that allows
    nss to generate and use insecure DH params that Java would be capable of
    using.
    
    This test case shows the ability to allow weak params, and
    that they are indeed 1024 bits
