Description

As support for PHP < 5.6.20 has been dropped, certain work-arounds which were in place to support older PHP versions can be removed.

The patches I'm attaching to this ticket are all fairly simple. I will add a more detailed description with each patch.

@dkarfa Thanks for your enthousiasm.

Regarding patch 48074.4.patch: this patch should not be committed as part of this ticket.

I left everything JSON out of this ticket on purpose as there is a separate ticket open for that and patches would too easily conflict otherwise.

See #47699

Patch 48074.6.patch LGTM.
