stress-ng V0.21.04 "Exasperating electron exerciser"

New stressors

• gamma - lgamma and tgamma libm function stessors
• ovpn - exercise the ovpn Linux kernel driver and its netlink API.
• pagescatter - scattered virtual address page mapping stressor
• sigstop - SIGSTOP/SIGCONT killing/signalling

New options

• buddystat - periodic Linux buddy allocator statistics (with fragmentation estimate)
• ios - show I/O read/write statistics
• exercise-feature - select stressors by specifying a list of one or more features to exercise
• exercise-syscall - select stressors by specifying a list of one or more system calls to exercise
• exercise-library - select stressors by specifying a list of one or more libraries to exercise
• exercised - show the features, syscalls and libraries exercised by executed stressors

Performance feaures:

• memrate stressor: use sse4.1 movntdqa for x86 128 non-temporal loads
