libcanberra-0.30+2-160000.2.2

- Change license to LGPL-2.1-or-later, per legal review.

- Update to version v0.30+2:
  + 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.

- Don't recommend the gtk modules unconditionally. They already have
  conditional supplements.
- Switch from packageand(x:y) to boolean dependencies
- Use %license

- Stabilize build:
  + Pass --disable-oss to configure: alsa is enabled and used
    already.
  + Pass --enable-udev to configure: ensure it is not accidentally
    being disabled.
  + Add pkgconfig(libudev) BuildRequires: used to be pulled in
    indirectly.

- Use %autosetup instead of %setup/%patch.

- Fix SRPM group. Update summaries.

- Modernize spec-file by calling spec-cleaner

- Remove the lynx build dependency: of questionable need.
- Build for Gtk3 unconditionally.
- Spec cleanup.

- Update to GNOME 3.20.2 Fate#318572

- Do not require sound-theme-freedesktop by libcanberra0: if this
  is wanted on a default install, it is up to the DE pattern to
  recommend/require this - it is not needed for the libraries
  proper functioning.
