2b556f8de9 Refactor the CPU scheduling subsystem 
This commits improves both readability and correctness of the scheduling-related
system calls. In terms of readability, it extracts all scheduling-related code
ouf of the process/ directory and put it in a sched/ directory. In terms
of correctness, the new scheduling subsystem introduces CpuSet and SchedAgent
types to maintain and manipulate CPU scheduler settings in a secure and robust way.
