So far the Unmanaged got released after an XCB_UNMAP_NOTIFY. This event gets created after xcb_unmap_window or after xcb_destroy_window. In the latter case the window is already distroyed and any of KWin's cleanup calls will cause a BadWindow (or similar) error. The idea to circumvent these errors is to try to wait for the DESTROY_NOTIFY event. To do so the processing of the release is slightly delayed. If KWin gets the destroy notify before the delay times out the Unamanged gets released immediately but with a Destroy flag. For this a new enum ReleaseToplevel is introduced and Unmanage::release takes this as an argument instead of the bool which indicated OnShutdown. Also this enum is added to Toplevel::finishCompositing so that it can ignore the destroyed case and not generate an error. REVIEW: 117422
