was ported back from 2.4 to 2.2 that means you can simply include the "openssl dhparam" output
in the certificate file. In addition by default the next 2.2 will also choose a prime length
corresponding to the RSA key length in the certificate. So in most cases user should be just
fine. If admins want to tune, they can by generating params and appending them to the cert

- static const unsigned char dh$num_p[]
+ static unsigned char dh$num_p[]
