[PATCH] RFC: CONTRIBUTING: Embrace gitlab

[Daniel Vetter]

So Rodrigo just broke the gitlab ci on libdrm, I figured perfect time
to start this discussion.

There's imo 2 reasons to do this:

- No more "oops, I broke make check". If we use gitlab merge requests
  gitlab CI will test everything, and we can set 2 checkboxes that
  disallow direct pushes (i.e. require merge requests), and that all
  merge requests must pass CI first.

- maintainer-tools is a small project with a small team and little
  activity. Much easier to figure out the details here than in one of
  our big projects. And there's lots to figure out, which we need to
  be able to explain (and have documented) for our 50+ team, if we
  ever want to use gitlab: commandline tools, emacs modes, best
  practices for setup, ...

To avoid this being an entirely hypothetical discussion, I've gone
ahead and created a merge request for this:

https://gitlab.freedesktop.org/drm/maintainer-tools/merge_requests/3

For keeping up with activity: Go to the main repo, click the alarm
icon (which probably says "Global" now), and change the setting to
"Watch". That should keep you updated on all issues and merge
requests, like with a mailing list.

v2: Add link to merge request.

+code, you should create an account on this GitLab instance, fork the core Weston
+repository, push your changes to a branch in your new repository, and then
+submit these patches for review through a merge request.
