TYPO3 Core

With the addition of the "virtual page-root"-feature (#33852) a person which is not admin now has a root-node to click on to get a full view of changes across all mountpoints (requested in #30630).
But the griddata-functions need to restrict data shown to the mountpoints visible to that person. Check if pid=0 (the real "page-root") is in the list of mountpoints, and if not fetch changes from below all mountpoints visible.
