xfs: bulkstat v5

This series imports relevant pieces of the V5 bulkstat code from the
kernel, establishes documentation for the new ioctls, and then converts
the existing xfrog_{bulkstat*,inumbers} callers to use the new ioctls.
Following that, we add a new xfs_io command to test the new ioctls, and
finally adapt scrub and spaceman to take advantage of the new xfrog
functionality.
xfs_scrub: batch inumbers calls during fscounters calculation

Improve the efficiency of the phase 7 inode counts by batching requests,
now that we have per-AG inumbers wrappers.
