[issue21308] PEP 466: backport ssl changes

[Ned Deily]

Ned Deily added the comment:

Some results from a quick build/test on OS X 10.9.4 with Xcode 5.1.1 clang and openssl 1.0.1h from MacPorts (similar results when built with Apple-supplied openssl 0.9.8y and on OS X 10.5.8 ppc with Apple-supplied openssl 0.9.7l):

- Modules/_ssl.c:2861:52: warning: invalid conversion specifier 'R'
      [-Wformat-invalid-specifier]
                     "unknown elliptic curve name %R", name);
                                                  ~^
- segfault on test_load_cert_chain (lldb traceback in attached file)
