bug#43725: 28.0.50; Include feature/native-comp into master

[Andrea Corallo]

Hi all,

this is to handle code-review and process whose final goal is to have
the feature/native-comp branch merged into master.

I'll try to make this as easy as possible implementing suggestions.
Also please feel free to install directly changes on the branch if you
feel.

Thanks in advance to the reviewers for the time.

  Andrea
