   - deleted patches httplib2 started to use certifi and this is already bent
     to use system certificate bundle.

   - handle the case when validation is disabled correctly. The
     'check_hostname' context attribute has to be set first, othewise a
     "ValueError: Cannot set verify_mode to CERT_NONE when check_hostname
 is
     enabled." exception is raised.

   - handle the case with ssl_version being None correctly

   - Use  ssl.create_default_context in the python2 case so that the system
     wide certificates are loaded as trusted again.

   - Source url must be https.

   - Spec file cleanups

   - Update to 0.10.3
     *  Fix certificate validation on Python<=2.7.8 without
        ssl.CertificateError
   - Update to 0.10.2
     * Just a reupload of 0.10.1, which was broken for Python3 because wheel
       distribution doesn't play well with our 2/3 split code base.
   - Update to 0.10.1
     * Remove VeriSign Class 3 CA from trusted certs
     * Add IdenTrust DST Root CA X3
     * Support for specifying the SSL protocol version (Python v2)
     * On App Engine use urlfetch's default deadline if None is passed.
     * Fix TypeError on AppEngine “__init__() got an unexpected keyword
       argument 'ssl_version’”
     * Send SNI data for SSL connections on Python 2.7.9+
     * Verify the server hostname if certificate validation is enabled
     * Add proxy_headers argument to ProxyInfo constructor
     * Make disable_ssl_certificate_validation work with Python 3.5.
     * Fix socket error handling
   - Remove httplib2-bnc-818100.patch, merged upstream.

   - Project moved from code.google.com to GitHub, fix the url accordingly

   - attempt to build multi-python

   - update and cleanup of httplib2-use-system-certs.patch, so that the
     passthrough is clean for python2 and so that it does the right thing in
     python3
