bpo-30102: Call OPENSSL_add_all_algorithms_noconf (#3112)
The ssl and hashlib modules now call OPENSSL_add_all_algorithms_noconf() on
OpenSSL < 1.1.0. The function detects CPU features and enables optimizations
on some CPU architectures such as POWER8. Patch is based on research from
Gustavo Serra Scalet.
