- Move LITMUS choice of next task inside pick_next_task() function
- Unfortunataly, litmus plugins' scheduling decisions need to access

on struct rq

- remove the call to litmus_tick() from scheduler_tick() just after
having performed the class task_tick() and integrate
litmus_tick() in task_tick_litmus()
- task_tick_litmus() is the handler for the litmus class task_tick()
method. It is called in non-queued mode from scheduler_tick()
