wsi timeout, wsi hrtimer, sequencer timeout and vh-protocol timer all now participate on a single sorted us list. The whole idea of polling wakes is thrown out, poll waits ignore the timeout field and always use infinite timeouts. Introduce a public api that can schedule its own callback from the event loop with us resolution (usually ms is all the platform can do). Upgrade timeouts and sequencer timeouts to also be able to use us resolution. Introduce a prepared fakewsi in the pt, so we don't have to allocate one on the heap when we need it. Directly handle vh-protocol timer if LWS_MAX_SMP == 1
