            Log:
            fully automate repository changes

Instead of performing error-prone manual changes in .repo files several times
per cycle, this patchset brings fully automated handling of such edits. All the
releng person needs to do is to set `rawhide_release` and
`updates_testing_enabled` variables (and of course adjust `Version` and
`Release`), and all the repos will be auto-magically populated with the correct
values during build (which includes `enabled=0/1` and `metadata_expire=6h/7d`).
The intention is to avoid human errors which inevitably happen (an example [1]).

This means:

* Rawhide/ELN repo files will get enabled for Rawhide builds, disabled otherwise.
* Standard repo files will get enabled for non-Rawhide builds, disabled otherwise.
* Updates-testing repo will get enabled per specified configuration (ignored on
  Rawhide).
* Base repo files will have short metadata expiration during development period
  ("Branched"), long expiration during stable period.

Everything is covered with tests, to prevent humans and automatons from doing
mistakes. That covers the automated changes to repo files, but also e.g. ensuring
that updates-testing is not enabled in a Final release by mistake.

Coupled with this changeset is an adjustment to certain repo files to make sure
all the sections defined in a single repo file have the same value
`metadata_expire=`, as it makes sense. And also in the spec file the rawhide
subpackage description was moved next to the subpackage definition, they were
split by mistake in the past, it seems.

If this gets merged, it will massively simplify Releng's Mass Branching SOP in
the future [2].
