client: Add wl_display_dispatch_queue_timeout

Browse source 
For dispatching messages on a queue with a timeout.

This slightly changes the samantics of wl_display_dispatch. Previously
it was possible for it to return even though there wasn't a single
dispatched event. The function correctly returned 0 in this case but it
is now used to indicate a timeout.
