TYPO3 uses $GLOBALS['LANG'] directly in some places, but since
TYPO3 v7, new code started to use a short hand protected method
"getLanguageService" in order to get IDE code completion and better
analysis of code.

This patch replaces all left-over places of $GLOBALS['LANG']
and encapsulates this into a short-hand method to streamline
TYPO3 Core's code base.
