     * Normalizes a file/directory path.

     *
     * - Convert all directory separators into `DIRECTORY_SEPARATOR` (e.g. "\a/b\c" becomes "/a/b/c")
     * - Remove trailing directory separators (e.g. "/a/b/c/" becomes "/a/b/c")
     * - Turn multiple consecutive slashes into a single one (e.g. "/a///b/c" becomes "/a/b/c")
     * - Remove ".." and "." based on their meanings (e.g. "/a/./b/../c" becomes "/a/c")
     *
     * Note: For registered stream wrappers, the consecutive slashes rule
     * and ".."/"." translations are skipped.
     *
     * @param string $path the file/directory path to be normalized
     * @param string $ds the directory separator to be used in the normalized result. Defaults to `DIRECTORY_SEPARATOR`.
