/** 
 * Scan directories and keep matching subtrees of the custom XML sitemap.
 *
 * This will ensure that there are XML sitemap custom links for every file
 * that matches, and remove any custom links that point to files that don't
 * exist. Note that if you call this with a more restrictive mask for a given
 * directory, the scan might remove custom links that point to existing files
 * (they just don't match the given $mask).
 *
 * $param array $directories
 *   An associative array keyed by directory names where the values are
 *   preg_match() regular expressions of the files to find.
 *
 * @return array
 *   A nested array of results, keyed by directory name, where the values are
 *   associative arrays with the keys 'add' or 'delete' where the values are
 *   filenames of links that were added or deleted during the scan.
 *
 * @see file_scan_directory()
