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.
