Merge of r4401, r4415: SSL changes: *) Added support for TLSv1.1, TLSv1.2 in ssl_protocols directive. Support for TLSv1.1 and TLSv1.2 protocols was introduced in OpenSSL 1.0.1 (-beta1 was recently released). This change makes it possible to disable these protocols and/or enable them without other protocols. *) Removed ENGINE_load_builtin_engines() call. It's already called by OPENSSL_config(). Calling it again causes some openssl engines (notably GOST) to corrupt memory, as they don't expect to be created more than once.
