Janne Snabb has done better detective work than I and found that NSS has
a hard-coded clamp on the number of DH bits used for ephemeral D-H and
GnuTLS's return value from gnutls_sec_param_to_pk_bits(GNUTLS_PK_DH,
GNUTLS_SEC_PARAM_NORMAL) is over that limit.
I'll add a clamp option to Exim and default it to the current NSS limit.
