[TASK] Disallow multi-line HTTP headers

PHP removed the support for this deprecated HTTP specification
in recent versions of PHP, thus we should remove these as well.

Besides that, we add an additional check for newlines
in GeneralUtility::locationHeaderUrl() to prevent potential
issues with Internet Explorer.
These lines can be removed once the minimum PHP requirement
are raised.
