Jiri Olsa 97f7e0b33d perf top: Save and display the drop count stats
Add drop count to 'perf top' headers:

  # perf top --stdio
   PerfTop:    3549 irqs/sec  kernel:51.8%  exact: 100.0% lost: 0/0 drop: 0/0 [4000Hz cycles:ppp],  (all, 8 CPUs)

  # perf top
  Samples: 0  of event 'cycles:ppp', 4000 Hz, Event count (approx.): 0 lost: 0/0 drop: 0/0

The format is: <current period drop>/<total drop>
