b6e80c7778 xfs: V5 filesystem format support 
Add support for new XFS on disk format. We have to handle optional
filetype fields in directory entries, additional CRC, LSN, UUID entries
in some structures, etc.

cad5cc0f5d zfs extensible_dataset and large_blocks feature support 
large blocks basically use extensible dataset feature, or to be exact,
setting recordsize above 128k will trigger large_block feature to be
enabled and storing such blocks is using feature extensible dataset. so
the extensible dataset is prerequisite.

Changes implement read support extensible dataset… instead of fixed DMU
types they dont specify type, making it possible to use fat zap objects
from bonus area.

5370dcfdae zfs: fix integer truncation in zap_lookup 
Size after shift could exceed 16 bits; use grub_unit32_t for result.

a139188eb5 xfs: Convert inode numbers to cpu endianity immediately after reading 
Currently XFS driver converted inode numbers to native endianity only
when using them to compute inode position. Although this works, it is
somewhat confusing. So convert inode numbers when reading them from disk
structures as every other field.

1570140f03 xfs: Fix termination loop for directory iteration 
Directory iteration used wrong position (sizeof wrong structure) for
termination of iteration inside a directory block. Luckily the position
ended up being wrong by just 1 byte and directory entries are larger so
things worked out fine in practice. But fix the problem anyway.

6210b8e8f7 zfs: add missing NULL check and fix incorrect buffer overwrite 
grub_memset should zero out padding after data end. It is not clear
why it is needed at all - ZFS block is at least 512 bytes and power
of two, so it is always multiple of 16 bytes. This grub_memset
apparently never did anything.

a1007c6af2 zfs: com.delphix:hole_birth feature support 
In the past birth was always zero for holes. This feature started
to make use of birth for holes as well, so change code to test for
valid DVA address instead.

54bd9a0610 Fix incorrect address reference in btrfs 
We encountered a weird random kernel initrd unpacking error on btrfs
and finally found it was caused by incorrect address reference in range
check for type GRUB_BTRFS_EXTENT_REGULAR and the entire result is
unpredictable.

This is a quick fix to make the address reference to the
grub_btrfs_extent_data structure correctly, not the pointer variable
to it.

Any suggestions to this patch is welcome.
