FreeNAS Code

move method to the file namespace

we don't need to validate the pool on dump time

use ForestStoreModel for TreeGrid (needs new type of pool serialize)

beautify TreeGrid summary for zpool status

alpha version of zpool status over GUI

tell Pool about zpool id

fix a case for zpool status parser when you've got "stripe" of single disks (not vdevs)

handle unavail = not ONLINE
use disk_name to detach an unavail disk from a pool

better way to validate the Pool

make the disk replacement works if there is more than one disk unavail
