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.
