Given an internal Drupal path, return the alias for the path.

This is similar to drupal_get_path_alias(), but designed to fetch all aliases at once so that only one database query is executed instead of severa or possibly thousands during sitemap generation.

Parameters

string $path: An internal Drupal path.

string $language: A language code to use when looking up the paths.
