Bryn M. Reeves a8b9e2eccd dmsetup: use timerfd for interval timing if available 
If the Linux timerfd interface to POSIX timers is available at compile
time use it for all report interval timekeeping. This gives more
accurate interval timing when the per-interval processing time is less
than the configured interval and simplifies the timestamp bookkeeping
required to keep accurate time.

For systems without timerfd support fall back to the simple usleep based
timer.
