Instead of determining which working copies are affected while applying the
commit queue, do this while creating the queue by actually creating a queue
per working copy.

This allows performing a working copy commit in a future step.

I expected a slight performance slowdown in this step, but it appears things
already get slightly faster than before, most likely just caused by using pre
sorted items.

  (compare_queue_items): New function.
  (svn_wc_process_committed_queue2): Use two loops to avoid wcroot work.
