Serapheim Dimitropoulos 829f9251cf OpenZFS 8491 - uberblock on-disk padding to reserve space for smoothly merging zpool checkpoint & MMP in ZFS
The zpool checkpoint feature in DxOS added a new field in the uberblock.
The Multi-Modifier Protection Pull Request from ZoL adds three new fields
in the uberblock (Reference: https://github.com/zfsonlinux/zfs/pull/6279).
As these two changes come from two different sources and once upstreamed
and deployed will introduce an incompatibility with each other we want
to upstream a change that will reserve the padding for both of them so
integration goes smoothly and everyone gets both features.

Porting Notes: Preserved MMP comments in uberblock struct.
