Comment:

 Thinking out loud: If libcurl < 7.34 cannot correctly negotiate a TLS1.2
 connection, how about we conditionally set the default transport order
 based on that?

 In `WP_Http::_get_first_available_transport()`:

 {{{
 $curl = curl_version();
 if ( 'https' === parse_url( $url, PHP_URL_SCHEME ) && version_compare(
 $curl['version'], '7.34', '<' ) ) {
     $transports = array( 'streams', 'curl' );
 } else {
     $transports = array( 'curl', 'streams' );
 }
 }}}

 What other compatibility issues is this likely to cause?
