The per-pt priv for event libs ended up overallocated at the context, and pointed-to by a single pointer composed into each pt. That means we can't do pointer arithmetic on it any more. Update a couple of stragglers in libuv event lib to use a pointer in the pt-priv for the event lib back to the pt instead. Also in foreign case if we start idle, there may not be anything happening to trigger the initial idle. So let each pt start with its idle active.
