Subject: - Added CURLFORM_STREAM as a supported option to curl_formadd() to
 allow an   application to provide data for a multipart with the read
 callback. Note   that the size needs to be provided with
 CURLFORM_CONTENTSLENGTH when the   stream option is used. This feature is
 verified by the new test case   554. This feature was sponsored by Xponaut.
