SilcClientConnection
    silc_client_add_connection(SilcClient client,
                               SilcClientConnectionParams *params,
                               char *hostname, int port, void *context);

    Allocates and adds new connection to the client. This adds the allocated
    connection to the connection table and returns a pointer to it. A client
    can have multiple connections to multiple servers. Every connection must
    be added to the client using this function. User data `context' may
    be sent as argument.  If the `params' is provided they are used by
    the routine.

    This function is normally used only if the application performed
    the connecting outside the library, and did not called the
    silc_client_connect_to_server function at all. The library
    however may use this internally.
