btrfs-progs: mkfs: allow UUID specification at mkfs time
Allow the specification of the filesystem UUID at mkfs time.
Non-unique unique IDs are rejected. This includes attempting
to re-mkfs with the same UUID; if you really want to do that,
you can mkfs with a new UUID, then re-mkfs with the one you
wanted.
(Implemented only for mkfs.btrfs, not btrfs-convert).
