Initial addition of cyclicdeadline and deadline_test

cyclicdeadline is a test that is similar to cyclictest but instead of
 using SCHED_FIFO and nanosleep() to measure jitter, it uses SCHED_DEADLINE
 and has the deadline be the wakeup interval.

deadline_test tries to create tasks under SCHED_DEADLINE that runs a
 measured amount per peroid. It checks to see if it succeeds in executing
 the measured runtime within a given period.

Both these tests are currently very crude, and will continue having
an overhaul.
