Remove support for OpenSSL 0.9.8 and 1.0.0topic/drop-openssl-098-and-100

They are no longer receiving security updates from the OpenSSL
development team since 2015-12.

We have kept basic compatibility until now because RHEL 5 still uses an
(heavily modified) OpenSSL 0.9.8e. The RHEL 5 will reach EOL on 2017-03,
thus it is now safe to assume nobody is still using such old versions of
OpenSSL.
