Re-structure the auth_ldap module to fit the new authentication model.  The authnz_ldap module provides an ldap authentication provider and an authorization handler.  It implements the authorization "require" values ldap-user, ldap-dn and ldap-group.  This restructure also moves auth_ldap out of the experimental directory.
