Returns a simple 404 Not Found page.
If fast 404 pages are enabled, and this is a matching page then print a simple 404 page and exit.
This function is called from drupal_deliver_html_page() at the time when a a normal 404 page is generated, but it can also optionally be called directly from settings.php to prevent a Drupal bootstrap on these pages. See documentation in settings.php for the benefits and drawbacks of using this.
Paths to dynamically-generated content, such as image styles, should also be accounted for in this function.
