Provide the other primes from RFC 3526.
Browse files Browse the repository at this point in the history 
Node just calls every function they can find. I've added the other ones
from RFC 3526 (although some of these are *quite* large) but, for now,
skipped the 768-bit and 1024-bit ones. Those are too small. See
nodejs/node#44539.

I've also reordered so DH_get_rfc7919_2048 is first. In so far as we
want to recommend DH at all, that's probably the one to list first.
