Fixing sched_sim and bringing it in synch with master

Introduction:

Existing RTEMS Priority SMP Scheduler supports Arbitrary Processor Affinities (APA) to allow the application program to instruct RTEMS to schedule a program on only a subset of the available processor cores. However, the existing implementation as it is, requires multiple traversals of the task set and is extremely inefficient. This project aims to add a new scheduling policy that augments the existing priority scheduler with Strong APA semantics in a more efficient manner.
