This will make it easier and more obvious for developers to run them
locally: I'm sure I'm not the only developer who had assumed that
`.gitlab-ci/` is private to the CI environment and inappropriate (or
perhaps even destructive) to run on a developer/user system.
The lint checks are automatically skipped (with TAP SKIP syntax) if we
are not in a git checkout, or if git or the lint tool is missing. They
can also be disabled explicitly with `meson test --no-suite=lint`,
which downstream distributions will probably want to do.
By default, most lint checks are reported as an "expected failure"
(with TAP TODO syntax) rather than a hard failure, because they do not
indicate a functional problem with GLib and there is a tendency for
lint tools to introduce additional checks or become more strict over
time. Developers can override this by configuring with `-Dwerror=true`
(which also makes compiler warnings into fatal errors), or by running
the test suite like `LINT_WARNINGS_ARE_ERRORS=1 meson test --suite=lint`.
One exception to this is tests/check-missing-install-tag.py, which is
checking a functionally significant feature of our build system, and
seems like it is unlikely to have false positives: if that one fails,
it is reported as a hard failure.
run-style-check-diff.sh and run-check-todos.sh are not currently given
this treatment, because they require search-common-ancestor.sh, which
uses Gitlab-CI-specific information to find out which commits are in-scope
for checking.
