       This function will export the Diffie-Hellman public key parameter
       found in the given public key.  The new parameter will be
       allocated using gnutls_malloc() and will be stored in the
       appropriate datum.

       To retrieve other parameters common in both public key and private
       key, use gnutls_dh_params_export_raw().

       This function allows for NULL parameters since 3.4.1.
