The patch adds two methods to SSLContext which return information about loaded x509 certs, CRL and CAs. 


>>> ctx = ssl.SSLContext(ssl.PROTOCOL_TLSv1)
>>> ctx.load_verify_locations(SVN_PYTHON_ORG_ROOT_CERT)
>>> ctx.cert_store_stats()
{'crl': 0, 'x509': 1}
>>> ctx.get_ca_list()
[{'issuer': ((('organizationName', 'Root CA'),),
             (('organizationalUnitName', ''),),
             (('commonName', 'CA Cert Signing Authority'),),
             (('emailAddress', ''),)),
  'notAfter': 'Mar 29 12:29:49 2033 GMT',
  'notBefore': 'Mar 30 12:29:49 2003 GMT',
  'serialNumber': '00',
  'subject': ((('organizationName', 'Root CA'),),
              (('organizationalUnitName', ''),),
              (('commonName', 'CA Cert Signing Authority'),),
              (('emailAddress', ''),)),
  'version': 3}]

New patch

* method has been renamed to get_ca_list() and returns only CA certs
* get_ca_list(binary_form=True) returns CA certs in DER format
* cert_store_stats() returns three elements: X.509 CA cert count, X.509 non-CA count and CRL count

Updated patch with Antoine's review:

* method is now called get_ca_certs()
* cert_store_stats() returns total amount of X.509 as 'x509' key and X.509 certs with CA purpose in 'x509_ca'.
* documentation

It looks like the doc for get_ca_certs wasn't missing, so now it appears twice in the docs.  I'm not sure which is the preferred wording, so I'll leave it to Christian to fix it.
