**Upgrade instructions**

No changes needed.

**Review instructions**

This the first of multiple PRs to cherry pick the changes from https://github.com/neos/flow-development-collection/pull/3474 from @nezaniel and @mhsdesign step by step and fix issues and breakiness. 

This is intended to be unbreaky but be the foundation for future refactorings that can at least partly be automated once we have really solid type informations. 


* Packages: ``Flow.Log``
