This new API, perf_buffer__consume, can be used as follows:
- When you have a perf ring where wakeup_events is higher than 1,
  and you have remaining data in the rings you would like to pull
  out on exit (or maybe based on a timeout).
- For low latency cases where you burn a CPU that constantly polls
  the queues.

Looks good, thanks. I'd really appreciate if you could follow up with
a fix to perf_buffer__free() as well. If not, I will get to it
eventually anyway :)
