Carlos Garnacho 5e8c808cfb ci: Add job for pushing coverity reports
This job does:
1. Download the coverity bundle and untar it
2. Build mutter using clang and the coverity tool
3. Compress the coverity report
4. Upload for analysis

Things to note:
- Analysis are throttled, as per https://scan.coverity.com/faq#frequency
  we qualify for 21 weekly builds, 3 daily. Mutter is sometimes a busy
  project, so it seems we'd get often those consumed early in the day.
  This is something we can resign to, but the times we'll try to upload
  a report to have it rejected make the operation kinda pointless and
  probably better throttled by ourselves.
- The task is manual, given the restrictions above.
- The task only applies on master, as the envvar holding the coverity
  token is protected in gitlab.
- I had to use clang as the coverity tool doesn't seem to work ATM with
  gcc as per recent Fedora.
- The coverity tarball is 1.2GB in size, which is a bit too big to have
  it downloaded each time. As per their upload instructions, the tarball
  gets updated twice yearly, so this is cached to minimize downloads.
- The coverity token for mutter is kept private/hidden in gitlab CI
  settings.

Mutter

Mutter is a Wayland display server and X11 window manager and compositor library.

When used as a Wayland display server, it runs on top of KMS and libinput. It implements the compositor side of the Wayland core protocol as well as various protocol extensions. It also has functionality related to running X11 applications using Xwayland.

When used on top of Xorg it acts as a X11 window manager and compositing manager.

It contains functionality related to, among other things, window management, window compositing, focus tracking, workspace management, keybindings and monitor configuration.

Internally it uses a fork of Cogl, a hardware acceleration abstraction library used to simplify usage of OpenGL pipelines, as well as a fork af Clutter, a scene graph and user interface toolkit.

Mutter is used by, for example, GNOME Shell, the GNOME core user interface, and by Gala, elementary OS's window manager. It can also be run standalone, using the command "mutter", but just running plain mutter is only intended for debugging purposes.

Git messages

Commit messages should follow the GNOME commit message guidelines. We require an URL to either an issue or a merge request in each commit. Try to always prefix commit subjects with a relevant topic, such as compositor: or clutter/actor:, and it's always better to write too much in the commit message body than too little.
