// multipart-encoded request.
// For a part to be treated as a file by the backend we need
// to provide a 'filename' value in the Content-Disposition
// header. The FileTransfer code doesn't escape the names of
// extra POST parameters[0][1], so we can take advantage of this
// and essentially inject our own header lines and filename
// value with a carefully-crafted HTTP POST field name that's
// passed to FileTransfer.upload.
// FIXME: This is basically a hack, and needs a better
// solution at some point.
