[Ugh, apply the patch _before_ checkin, dopey]
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.
