stress-ng V0.18.03 "persistent process pressurizer"

New Stressors:

lockmix - mixed file locking stressor
fibsearch - Fibonacci search (like bsearch, but uses less compute)
bubblesort - inefficient classic bubble sort

New options:

--c-state - show C state residency at end of stress testing
--pause N - pause N seconds between each stressor invocation to allow for system to cool
,
New stressor classes:
fp, integer, ipc (inter-process communication), sort and vector
