tools lib traceevent: Add hrtimer plugin
Backporting hrtimer plugin.
Backported from Steven Rostedt's trace-cmd repo (HEAD 0f2c2fb):
git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/trace-cmd.git
This plugin adds function field resolving for following tracepoint
events:
timer:hrtimer_expire_entry
timer:hrtimer_start
The diff of 'perf script' output generated by old and new code: (data
was generated by 'perf record -e 'timer:hrtimer*' -a')

Check the 'function' field is translated into the function name.
