   CURLOPT_SSL_CTX_FUNCTION to set a callback that gets called with the
   OpenSSL's ssl_ctx pointer passed in and allow a callback to act on it. If
   anything but CURLE_OK is returned, that will also be returned by libcurl
   all the way back. If this function changes the CURLOPT_URL, libcurl will

We need to make sure that when we init a 'connectdata' struct and then
afterwards check for and re-use another one, we must be careful so that the
newly set values are transmitted and used in the surviving connectdata struct.
