libwayland-server patch shuffling globals order

Attaching a patch that can be applied to the upstream wayland repository. It'll
cause globals to be sent in a random order every time a wl_registry is
retrieved by the client. With these patches GTK+ seems to be able to start
without a problem even with this patch applied.

The question though is what globals should be required for GTK+ to succeed. Now
it'll just continue even if it didn't receive any globals (even wl_shm),
instead probably failing in other places. While wl_compositor,
wl_subcompositor, wl_shm, wl_seat, wl_data_device and xdg_shell are more or
less required, wl_output may not be there during startup due to hot plugging or
other reasons. So, what globals should be required for initialization to
succeed?
