- BuildRequires: git.
- Manage the source directory as a git repo.
- Use git-am(1) to apply patches instead of %patch.
- Reformat a bunch of patches to conform to git-am's rules.
- Add wfb to file manifest.
- Drop afb, sorry Amiga users.
- Delete the SecurityPolicy man page from the buildroot, until we have a
  xorg-x11-server-common.
- Update to today's snapshot.
