Log Message:
-----------
modules/dialog: Prevent "unable to find dialog" WARN messages caused by
accessing a dialog in the "deleted" state (often happens with simultaneous BYE
requests when both UAs hang up at the same time).

    - Move POINTER_CLOSED_MARKER from dlg_cb.c into dlg_hash.h for common
      usage.
    - in lookup_dlg() and internal_get_dlg(), return POINTER_CLOSED_MARKER when
      dialog is found but in the DLG_STATE_DELETED state.
    - in dlg_onroute(), abort request processing if dialog is found to be in
      the "deleted" state.
