    ci: Add GitLab CI description file
    
    We're mostly interested into building and testing everything that gets
    pushed to the repository — including merge requests.
    
    When pushing tags, though, we should assume we're spinning a release, so
    let's run the dist target, and store the tarball, and the generated
    documentation while we're at it, as artifacts on GitLab.
    
    The Dockerfile for the image used for the build is included in tree, and
    published on Docker Hub. Using a custom image allows us to avoid the
    costly "download and install build dependencies" phase, as well as
    controlling the environment a little bit better.
