Changes v3 -> v4:
- re-order arch-specific options for ease of review
- rebase; drop applied patch about man pages (Thomas)

Changes v2 -> v3:
- rework completely the depednencies on X11 libraries (Samuel)
- only install keys when the server is enabled (Samuel)

Changes v1 -> v2:
- new package python-lxml, needed for opengl-registry (Tomas P.)
- cleanup opengl-registry and nvidia-driver (Thomas P.)
- drop applied patches (Thomas P.)
