added a test case to exercise a bug in ngx_proxy's ssl handshake timeout handling (see http://mailman.nginx.org/pipermail/nginx-devel/2014-July/005627.html ).
feature: SSL/TLS cosocket API

* added new method sslhandshake() to the stream-typed cosocket objects.
* added new configuration directives lua_ssl_trusted_certificate,
  lua_ssl_verify_depth, lua_ssl_crl, lua_ssl_protocols, and
  lua_ssl_ciphers.

Thanks aviramc for the original patch in #290.
