libpam: avoid infinite recursion with includes
When there's a loop of configuration files consisting solely of includes
the recursion depth level is never incremented and thus no upper limit is
enforced. This leads to a crash caused by a stack overflow.
This patch updates the logic to track both the number of includes as well
as the number of substacks we are on; ultimately adding a new parameter
to track this information.
