    pluto: implement ECP DH19+DH20+DH21 Diffie–Hellman–Merkle key exchange in ike_alg_nss_modp.[hc]
    
    Known to interop with self and strongswan.
    
    A quirk with some code using NSS means it will fail when
    combined with HMAC_MD5 PRF (this code helps to flush out
    the unrelated bug).
