SSL: initialization changes for OpenSSL 1.1.0. OPENSSL_config() deprecated in OpenSSL 1.1.0. Additionally, SSL_library_init(), SSL_load_error_strings() and OpenSSL_add_all_algorithms() are no longer available if OPENSSL_API_COMPAT is set to 0x10100000L. The OPENSSL_init_ssl() function is now used instead with appropriate arguments to trigger the same behaviour. The configure test changed to use SSL_CTX_set_options(). Deinitialization now happens automatically in OPENSSL_cleanup() called via atexit(3), so we no longer call EVP_cleanup() and ENGINE_cleanup() directly.
