Hi all,

This submission extends xfs_repair and xfs_admin to support adding the
inode btree counter and bigtime features to an existing v5 filesystem.
The first three patches lay the groundwork in both tools for performing
upgrades, and the last two patches add the ability to add features.

v2: Rebase to 5.10-rc0
v3: respond to reviewer comments
v4: document which kernel version these new features showed up in
v5: move all the upgrader code to xfs_repair per Eric suggestion, which
    eliminates a bunch of fragile db/admin/repair coordination.
v6: update mkfs/admin/repair manpages to identify CLI options that apply
    only to V4 fses and are therefore deprecated
v6.1: repost after rebasing the previous two series

If you're going to start using this mess, you probably ought to just
pull from my git trees, which are linked below.

This is an extraordinary way to destroy everything.  Enjoy!
Comments and questions are, as always, welcome.
