HEADS UP: ZFS v28 merged to 8-STABLE

[Martin Matuska]

Hi,

I have merged ZFS version 28 to 8-STABLE (revision 222741)

New major features:

- data deduplication
- triple parity RAIDZ (RAIDZ3)
- zfs diff
- zpool split
- snapshot holds
- zpool import -F. Allows to rewind corrupted pool to earlier
  transaction group
- possibility to import pool in read-only mode

For updating, there is a compatibility layer so that in the update phase
most functionality of the new zfs binaries can be used with the old
kernel module and old zfs binaries with the new kernel module.

If upgrading your boot pool to version 28, please don't forget to read
UPDATING and properly update your boot code.

Thanks to everyone working on the ZFS port, especially to
Pawel Jakub Dawidek (pjd) for doing most of the work!
