Tony Hutter ad796b8a3b Add zpool status -s (slow I/Os) and -p (parseable) 
This patch adds a new slow I/Os (-s) column to zpool status to show the
number of VDEV slow I/Os. This is the number of I/Os that didn't
complete in zio_slow_io_ms milliseconds. It also adds a new parsable
(-p) flag to display exact values.
