wlroots 0.14.0

Release highlights:

- Renderer refactoring work is well underway: everything now uses the
  new infrastructure under-the-hood except the DRM backend's primary
- The Pixman software renderer has been merged, alongside new allocators
  (shared memory for Wayland/X11 and DRM dumb buffers).
- Session management is now completely offloaded to libseat.
- Support for the xdg-activation-v1 protocol has been merged.
