Merge r682369 from trunk:

* Remove call to apr_reslist_destroy. With the latest trunk version of
  apr-util this causes a lock during shutdown as at the point of time we would
  execute apr_reslist_destroy the reslist is already destroyed, because we are
  in a cleanup of the same pool where the reslist registered itself as
  precleanup.
  With apr-util 1.3.x calling apr_reslist_destroy is not really useful and
  needed in this case as we are in a cleanup that was registered against the
  same pool that is used by the reslist. As it was registered *after* the
  reslist was created it just runs *before* the reslist cleanup would run. This
  is somewhat pointless here and we could leave the job of destroying the
  reslist to the reslist cleanup.
