Bump OPENSSL_VERSION_NUMBER to 1.1.1.

With TLS 1.3 and Ed25519 support, we're much closer to OpenSSL 1.1.1
these days than OpenSSL 1.1.0. I've also added a test to keep
OPENSSL_VERSION_NUMBER and OPENSSL_VERSION_TEXT in sync.

Update-Note: Some OPENSSL_VERSION_NUMBER/OPENSSL_IS_BORINGSSL checks may
need to be updated. Hopefully even more can go away.
