mkfs: Take two block devices as arguments. Write everything to metadata
dev, and the superblock to the data dev. UUIDs match. Differentiate by
checking a bit in a new "flags" field in the superblock.
Refactor device_size() a little. Convert spaces to tabs.
Move code to pretty-print sizes to dev.c so we can use it in error
messages there, as well as in mkfs.c.
print: Include flags in output.
Add -D and -M options for setting max dev sizes
Allow sizes to be specified using units like "K", "G" etc.
Note: -D option replaces -S option, and uses above units rather than
the number of 4k data blocks.
Update man pages for cmdline changes.

Add the df command which uses the new alloc_detail ioctl to show df for
the metadata and data devices separately.

instead of a big-endian binary blob.

The kernel has long sinced moved away from symbolic printing of key
cones and types, and it just removed the MAX values from the format
header. Let's follow suit and get rid of the zone and type strings.

are no longer identified by the kernel module.

The format no longer has statically configured named slots. The only
persistent config is the number of monts that must be voting to reach
quorum. The quorum blocks now have a log of successfull elections.

Add support for the xattr tags which can hide or index xattrs by their
name. We get an item that indexes inodes by the presence of an xattr, a
listxattr_raw ioctl which can show hidden xattrs, and an ioctl that
finds inodes which have an xattr.

Move the magic value that identifies the super block into the block
header and use it for btree blocks as well.

Update the format header to reflect that the kernel now uses a locking
service instead of using an fs/dlm lockspace. Nothing in userspace uses
locking.

The server no longer stores the address to connect to in the super
block. It's now stored in the quorum config and voting blocks.
