[TYPO3-core] #53682, PHP 5.5.6, call-time pass-by-reference, PHP 5.6

This sounds correct as we expect people to actively check and adapt if
their extension is not compatible anymore. Furthermore the reference
operator is deprecated and as such it's wrong to keep it much longer. As
soon as 6.2 is rock solid and out, usage of 6.1 and 6.0 will decrease.

I would prefer a solution where the extension author actively uses
another implementation for < 6.2, adding complexity and making TYPO3
even more slow for something deprecated since ages does not look like a
good approach.

Do you already have a patch hanging somewhere? We may "try" and see a
bit how it behaves (I extended the toolbar as well so I could check in
my own extension) and then think further.

Kind regards
