xfs: online repair of AG btrees

Now that we've spent a lot of time reworking common code in online fsck,
we're ready to start rebuilding the AG space btrees.  This series
implements repair functions for the free space, inode, and refcount
btrees.  Rebuilding the reverse mapping btree is much more intense and
is left for a subsequent patchset.  The fstests counterpart of this
patchset implements stress testing of repair.
