    ci: Add Dockerfile
    
    It is a waste of time to reinstall all fedora packages for each job.
    Copy and adapt Dockerfile and scripts from glib.

+## Docker image
+
+GitLab CI jobs run in a Docker image, defined here. To update that image
+(perhaps to install some more packages):
+
+1. Edit `.gitlab-ci/Dockerfile` with the changes you want
+2. Edit `.gitlab-ci/run-docker.sh` and bump the version in `TAG`
+3. Run `.gitlab-ci/run-docker.sh` to build the new image, and launch a shell
+   inside it
+    * When you're done, exit the shell in the usual way
+4. Run `.gitlab-ci/run-docker.sh --push` to upload the new image to the GNOME
+   GitLab Docker registry
+    * If this is the first time you're doing this, you'll need to log into the
+      registry
+    * If you use 2-factor authentication on your GNOME GitLab account, you'll
+      need to [create a personal access token][pat] and use that rather than
+      your normal password
+5. Edit `.gitlab-ci.yml` (in the root of this repository) to use your new
+   image
+
