    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')
    
      --- script.hrtimer.old
      +++ script.hrtimer.new

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