Added zpios-sanity.sh script to validate common configurations.
This script was added to provide a simple way to check that zpool layers correctly on all the standard linux block device types. It's still a little fragile if there a hiccup in say the md or lvm tool chain but aside from that it works well. The 'make check' target now also calls this script in a safe mode which only operates on files and loopback devices. To check other block devices types is must be explicitly run by hand because it will overwrite various block devices.
