Display the system status on all pages and store it in a variable

With so many years of inactivity wonder if this can be closed?

I suppose there could still be something in this. If a status report item fails, the "One or more problems..." message is only displayed on /admin/content and /admin/config via the controller, but update.module displays messages about required updates on almost all admin pages via hook_page_top().

I agree with longwave: Requirement errors should be displayed on any admin page, similarly to update messages.

The patch needs to be re-rolled.

I removed the issue tag, since there is already an issue for Drupal 7 ( 📌 Backport "Display the system status on all pages and store it in a variable" Needs review ).
