FreeNAS Code

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

Auto-Commit of i18n data from Pootle for GUI

Added options for network|geom|zfs|hardware configuration.

Caused more problems than it solved

Restructure 4K disk handling:

- Only taste disk for 4k when we don't know we are going to do 4k disks.
Also, taste only the first disk rather than all disks;
- Remove _init_zfs_disk which is bitrot and not unused.

- Extract common code for ZFS vdev manipulation into one __prepare_zfs_vdev
and eliminate the duplicated code;
- aclmode=passthrough and aclinherit=passthrough should be set at creation
time rather than after creation;
- reload_disk() only at last.

Split the partitioning into another sequence so no cache invalidation is
needed for every disk but only once after we finished everything.

Add sge driver, fixes ticket 568

- Only restart smartd when needed.
- Fix notifier in a different way. Creating gpt partition changes
the topology so we need to invalidate cache there.

better way to validate the Pool
