    dh parameters update, new values & default


    * add three new exim-specific dh parameter constants; state provenance,
      but no way for others to verify; this is a signed commit, which is
      about as much as we can do for the truly paranoid: provide an audit
      trail.
    * add the rfc 7919 dh primes
      + no tls feature negotiation, per 7919, but the dh primes can be used
        if folks so choose
    * fixed broken format string in util/gen_pkcs3.c
    * tried to make gen_pkcs3.c support q values.
      + turns out, q doesn't affect the pem and that's not a mistake in my
        initialisation; i've checked with a cryptographer, we're losing some
        server-side optimizations but not any security properties for our
        scenario.


    fixes: 1895
