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.

The error return conventions were confused, resulting in main exiting
with success when command execution failed.

Remove the ctrstat command. It was built back when we had a handful of
counters. It's output format doesn't make much sense now that we have
an absolute ton of counters. If we want fancy counter output in the
future we'd add it to the counters command.

Add a command to output the sysfs counters for a volume, with the option
of generating a table that fits the terminal.

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.

The stage command was trivially implemented by allocating, reading, and
staging the entire region in buffer. This is unreasonable for large
file regions. Implement the stage command by having it read each
portion of the region into a smaller buffer, starting with a meg.

mkfs needs to make sure that a device is large enough for a file system.
We had a tiny limit that almost certainly wouldn't have worked.
Increase the limit to a still absurdly small but arguably possible 16
segments.

Update the format header and add a man page which describes the
corruption messages that the kernel module can spit out.

Make the changes to support the new small key struct. mkfs and print
work with simpler keys, segment items, and manifest entries. The item
cache keys ioctl now just needs to work with arrays of keys.

Lots of tests run scout stat and parse a single value. Give them an
option to have the only output be that value so they don't have to pull
it out of the output.
