- Add three new functions to support circular run queues.
- runq_add_pri allows the caller to position the thread at any rqindex
regardless of priority.
- runq_choose_from() chooses the lowest priority thread starting from a given
index. The index is updated with the rqindex of the chosen thread. This
routine is used to pick the lowest priority relative to a given index.
- runq_remove_idx() updates the index if the run queue that held the removed
thread is now empty.
