Initial version of circuit-based cell queues. Instead of hammering or_conns with piles of cells, queue cells on their corresponding circuits, and append them to the or_conn as needed. This seems to work so far, but needs a bit more work. This will break the memory-use-limitation patch for begin_dir conns: the solution will be a fun but fiddly.
