    Add .gitlab-ci.yml for build testing
    
    This adds compilation testing using meson on the gitlab instance. It
    uses a prebuild image built, described in .gitlab-ci/Dockerfile, based
    on Fedora 29.
    
    The image is build and published by running:
    
      cd .gitlab-ci/
      docker build -t registry.gitlab.gnome.org/gnome/mutter/master:v1 .
      docker push registry.gitlab.gnome.org/gnome/mutter/master:v1
    
    Resolves: https://gitlab.gnome.org/GNOME/mutter/merge_requests/132
