ftrace: add trace-cmd for ftrace control and config
Rather than manually configuring ftrace, trace-cmd was created
to provide a more user friendly interface to the tracer.
Some examples are:
# ./trace-cmd record -e all ls /bin
Then to see the information:
# ./trace-cmd report
To see just a subsystem:
# ./trace-cmd record -e irq ls /bin
To list the available trace events:
# ./trace-cmd list -e
You can also trace a single trace point with one of two methods:
# ./trace-cmd record -e sched:sched_wakeup ls /bin
Or simply:
# ./trace-cmd record -e sched_wakeup ls /bin
This tool also works with tracers (plugins) as well as events
# ./trace-cmd list -p
