The cpu set specified by the app must be within the range of the process mask in the cfg file. Also per-process cpu enumeration is supported.

Please hold on reviewing or merging this pull request. I noticed that the current affinity only support pinning the call thread itself (i.e., 0 for the pid argument). I would like to extend to cover pinning other threads too. |

I reused the Linux OS thread id stored in scheduler to figure out the corresponding thread id. Now please go on reviewing the code. |

Implement the visualization of sched_set/getaffinity syscalls. As requested in #81.
Try to be compatible with the current process mask and per-process CPU enumeration. The cpu set specified in sched_setaffinity must be within the process mask in cfg file.
Since pthread_set/getaffinity_np are implemented on top of sched_set/getaffinity, they are also supported.
Also included a small test program (as a demo).
