rhe c2329831fb openssl: fix for OpenSSL 1.0.0t 
* ext/openssl/ossl_ocsp.c: The "reuse" behavior of d2i_ functions does
  not work well with OpenSSL 1.0.0t. So avoid it.

* To submit the request we'll POST the request to the OCSP URI (per RFC

* display the status as a string:
*
* puts response.status_string #=> successful
*
* Next we need to know the response details to determine if the response
* matches our request. First we check the nonce. Again, not all CAs
* support a nonce. See Request#check_nonce for the meanings of the
* return values.
*
* p request.check_nonce basic_response #=> value from -1 to 3
*
* Then extract the status information for the certificate from the basic
* response.
*
* single_response = basic_response.find_response(certificate_id)
*
* unless single_response
* raise 'basic_response does not have the status for the certificiate'
