Menu handler for private file transfers.

If one or more modules returned headers the download will start with the returned headers. If a module returns -1 drupal_access_denied() will be returned. If the file exists but no modules responded drupal_access_denied() will be returned. If the file does not exist drupal_not_found() will be returned.
