We now insert tasks in a certain sequence in the run queue. The sorting key currently is the arrival order. It will now be possible to apply a "nice" value to any task so that it goes forwards or backwards in the run queue. The calls to wake_expired_tasks() and maintain_proxies() have been moved to the main run_poll_loop(), because they had nothing to do in process_runnable_tasks(). The task_wakeup() function is not inlined anymore, as it was only used at one place. The qlist member of the task structure has been removed now. The run_queue list has been replaced for an integer indicating the number of tasks in the run queue.
