* This function has various possible results:
* 1) $lUid unchanged -
* there was nothing to do for langvis and the overlay is requested is fine
* 2) $lUid == null
* is relevant if we did the overlay ourselfs and the processing within getPageOverlay function is not relevant anymore
* 3) $lUid changed
* is relevant if we just changed the target-languge but require getPageOverlay to proceed with the overlay-chrunching
* 4) $lUid changed to 0 (which may be the case for forced fallbacks to default). Please check Core Setting hideIfNotTranslated in this case to be sure the page can be shown in this case
