*applications tested

1. rt-app
- "rt-app" is a test application that starts multiple periodic threads
  in order to simulate a real-time periodic load

  - run example

  root@qemux86:~# rt-app -t 100000:35000:d -D 1
  [rt-app] <notice> [0] Using SCHED_DEADLINE policy:
  [rt-app] <notice> [0] starting thread with period: 100000, exec:
  35000,deadline: 100000, priority: 10
  [rt-app] <notice> [0] Locking pages in memory

  2. schedtool
  - scheduler test tool
  - run example
  root@qemux86:~# schedtool -E -t 10000:100000 -a 0 -e yes > /dev/null&
  root@qemux86:~# schedtool -E -t 30000:100000 -a 0 -e yes > /dev/null&
