[XFS] Ondisk format extension for extended attributes (attr2). Basically,
the data/attr forks now grow up/down from either end of the literal area,
rather than dividing the literal area into two chunks and growing both
upward. Means we can now make much more efficient use of the attribute
space, incl. fitting DMF attributes inline in 256 byte inodes, and large
jumps in dbench3 performance numbers. It is self enabling, but can be
forced on/off via the attr2/noattr2 mount options.
