Dustin Carlino 7170efbdba Improve some gridlock cases near roundabouts particularly. #114, #75
1) If a car is blocked by a conflicting turn and is part of a cycle,
   wake up the car blocking it. In some cases, this wakes it up faster
   and unsticks things. Otherwise, it just wastes a little bit of time.
2) If a car is part of a cycle, allow blocking-the-box.
3) Continue sorting people at a stop sign by the time they've been
   waiting. But for cars "overflowing" their current lane, move them to
   the front of this ordering. It unsticks one particular situation.
4) Fix wakeup_waiting entirely. Before, it was waking up protected turns
   before permitted, but otherwise the ordering was arbitrary. Now actually
   respect stop sign ordering. I expect this to improve many other
   situations than the one I was checking.

This was all motivated by one particular roundabout in Poundbury. It
doesn't solve gridlock there, but it gets past a major blockage.
