BREAKING CHANGE: remove unused global configuration

[romanc]

Description

According to @FlorianDeconinck, this global configuration is not used anymore and thus can and should be deleted. It was a way to "quickly configure" some things "back in the days".

This is a follow-up of #250 and in preparation for #257.

How has this been tested?

If anything was still using these functions, the compiler would complain (worst-case at runtime).
