nestable calls to thread_[state_]awake

Remove all the "if asleep then awake ..." stuff from the code by making
awake/asleep calls nestable, whereas before it "awake ; awake" really
meant a transition through "asleep".  This self-evidently necessitates
fixing those places where the old behaviour was relied on upon, but
fortunately those are few.
