Arnaldo Carvalho de Melo 81e3d8b2af perf trace beautify ioctl: Beautify perf ioctl's 'cmd' arg 
Also trying a new approach, using the copy of uapi/linux/perf_event.h we
auto generate the string tables, then include it in the ioctl cmd
beautifier.

This way either the perf developers will add the new commands to the
tools/ copy, like is happening with other areas of tools/include/ (bpf.h
comes to mind), or we'll be notified when building perf that our copy
drifted.

E.g., looking at some of the perf ioctls issued by the 'perf test' test cases:

  # (perf trace -e perf_event_open,ioctl perf test)  2>&1 | egrep "(cmd: PERF_|perf_event_open)"
