Willy Tarreau 501260bf67 MEDIUM: task: always ensure that the run queue is consistent 
As found by Thierry Fournier, if a task manages to kill another one and
if this other task is the next one in the run queue, we can do whatever
including crashing, because the scheduler restarts from the saved next
task. For now, there is no such concept of a task killing another one,
but with Lua it will come.

A solution consists in always performing the lookup of the first task in
the scheduler's loop, but it's expensive and costs around 2% of the
performance.

Another solution consists in keeping a global next run queue node and
ensuring that when this task gets removed, it updates this pointer to
the next one. This allows to simplify the code a bit and in the end to
slightly increase the performance (0.3-0.5%). The mechanism might still
be usable if we later migrate to a multi-threaded scheduler.
