+ gtk: Don't assume all GdkDisplays are GdkX11Displays.
- Migrate package to obs_scm: we don't expect changes in git to
happen anymore, but it's the line used across all GNOME packages.
- Call autogen.sh in build section: the git checkout is not
bootstrapped.
- Drop libcanberra-broadway-fix.patch: part of the upstream git
tree.
- Pass --with-systemdunitdir=no to configure: dbus-broker newly
pulls in systemd, but we have been running without those service
files for like ever. With libcanberra being in maintenance only
mode, there seems to be no justification to change this now.
- Do not package documentation: building them requires lynx, which
seems a bit exaggerated.
