/**
 * Fix the temporary filename provided by the plupload library.
 *
 * Newer versions of the plupload JavaScript library upload temporary files
 * with names that contain the intended final prefix of the uploaded file
 * (e.g., ".jpg" or ".png"). Older versions of the plupload library always use
 * ".tmp" as the temporary file extension.
 *
 * We prefer the latter behavior, since although the plupload temporary
 * directory where these files live is always expected to be private (and we
 * protect it via .htaccess; see plupload_handle_uploads()), in case it ever
 * isn't we don't want people to be able to upload files with an arbitrary
 * extension into that directory.
 *
 * This function therefore fixes the plupload temporary filenames so that they
 * will always use a ".tmp" extension.
 *
 * @param string $filename
 *   The original temporary filename provided by the plupload library.
 *
 * @return string
 *   The corrected temporary filename, with a ".tmp" extension replacing the
 *   original one.
