* Try finding a matching configuration directory by stripping the website's
* hostname from left to right and pathname from right to left. The first
* configuration file found will be used, the remaining will ignored. If no
* configuration file is found, return a default value '$confdir/default'.

* Example for a fictitious site installed at
* http://www.drupal.org:8080/mysite/test/ the 'settings.php' is searched in
* the following directories:

* 1. $confdir/8080.www.drupal.org.mysite.test

* 3. $confdir/drupal.org.mysite.test
