TYPO3 Core

The function t3lib_befunc::getLabelFromItemlist() gets you the label of a tca field in the backend. This works nicely but problem is that the label can be changed with TsConfig with something like

TCEFORM.tt_content.section_frame {
  addItems.100 = New item
  altLabels.1 = Change me
}

Also new items are not currently handled at all, see the related issues.

The new function will take care of that and makes it possible to change the core to use that.
