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).

Fedora had a bug where a poor user thought that --alloc-start
meant that the filesystem would be created at that offset into
the device, rather than just starting allocations at that offset.
A subtle difference, but worth clarifying, because the manpage
is misleading on this point.
The original commit log for this option says:
Add mkfs.btrfs -A offset to control allocation start on devices
This is a utility option for the resizer, it makes sure to allocate
at offset bytes in the disk or higher. It ensures the resizer will have
something to move when testing it.
so allude to that intended use in the manpage.

The 'btrfsck' command has been deprecated in favor of 'btrfs check'. For
compatibility install a symlink to the btrfs-check.8 manpage.
