Nat Goodspeed 2bffbddeaa Reimplement waiting_queue::push() using pointer-to-pointer trick. ...

Change waiting_queue::head_ from worker_fiber* to fiber_base* for uniformity
with worker_fiber::nxt_. This lets push() scan from head_ with a fiber_base**,
looking for the right insertion point. Insertion then becomes a couple
unconditional assignments.

Because push() always scans from head_, tail_ was actually never used. Remove
it.
