Illumos #1644, #1645, #1646, #1647, #1708
1644 add ZFS "clones" property 1645 add ZFS "written" and "written@..." properties 1646 "zfs send" should estimate size of stream 1647 "zfs destroy" should determine space reclaimed by destroying multiple snapshots 1708 adjust size of zpool history data References: https://www.illumos.org/issues/1644 https://www.illumos.org/issues/1645 https://www.illumos.org/issues/1646 https://www.illumos.org/issues/1647 https://www.illumos.org/issues/1708 This commit modifies the user to kernel space ioctl ABI. Extra care should be taken when updating to ensure both the kernel modules and utilities are updated. This change has reordered all of the new ioctl()s to the end of the list. This should help minimize this issue in the future.
