xfs: add version 3 inode format with CRCs
Add a new inode version with a larger core. The primary objective is
to allow for a crc of the inode, and location information (uuid and ino)
to verify it was written in the right place. We also extend it by:
a creation time (for Samba);
a changecount (for NFSv4);
a flush sequence (in LSN format for recovery);
an additional inode flags field; and
some additional padding.
These additional fields are not implemented yet, but already laid
out in the structure.
[dchinner@redhat.com] Added LSN and flags field, some factoring and rework to
capture all the necessary information in the crc calculation.
