Stop the misleading double-accounting of flips when we have multiple

overlay: Correct layout of ring/seqno in raw sample
...
For seqno completion, the events are too coarse i.e. one event may
signal the completion of a few seqno. We will need to sort the events to
properly compute the busy times.

Still a little too course as we add multiple overlapping seqnos and
waits.

overlay: Couple wait begin/end events together to fix accounting
...
Since the events may be processed out of order (due to per-cpu
ringbuffers) we need to be careful to associated wait pairs in order to
compute the correct elapsed time.

overlay: Perf output redirection must be done after mmap()
...
Effectively you choose to redirect the output of an event instead of
mmapping it directly - but the target must already be mmapped.

We can now record when a pageflip occurs by listening for the flip
tracepoint. Merely proof of principle at this point.
