OpenSSL doesn't support static DH, actually.  There's anonymous and
non-anonymous ephemeral DH, there's static and ephemeral ECDH, but no
static DH with DH certificates.  (There's also some code that doesn't
totally neglect the possibility of having DH certificates, but this
doesn't mean it is actually used anywhere.)
