It's been causing me quite some headache, and I don't see the point in
jumping through the hoops for something that can be trivially fixed by
having the required build tools.
A new target `check-gen-updated` to verify that all derived/generated
files that were modified were also checked in. This is used on CI to
check, and is not added to `check` since it'll complain on dirty
trees, i.e., before the devs check in their changes.

We split into quick smoke-tests, normal-tests, and valgrind-tests. The
first provides a quick-abort preventing overusing resources on what
will be a failed run anyway.
We'd like to have some more structure to the tests, with smoke-tests
going first, followed by valgrind and normal tests running in
parallel. So to cut down on the copy-pasta we extract the scripts from
the yaml, into their own files from where they can be easily invoked.
We don't have a good way of referring to the configuration that
failed, so let's give them a numberic ID. Particularly useful for the
artifacts that'd be overwritten otherwise.
