SSLv3 has been compromised a year ago by what is known as POODLE
(https://en.wikipedia.org/wiki/POODLE). Every major browser have now
dropped support for SSLv3 and distribution are starting to do so also.
It is a good timing for us to do so, especially as it breaks build on
some distribution.
This seems to come from some intention to fetch dh from openssl somewhow but
it was never implemented. fh always stays 0 since its init and thus we can
remove the code it guards.
