The check for a small device didn't return an error code because it was
copied from error tests of ret for an error code. It has to generate
one, do so.

Use little helpers to insert items into new single block btrees for
mkfs. We're about to insert a whole bunch more items.

The calculation of the last valid data blkno was off by one. It was
calculating the total number of small blocks that fit in the device
size.

Track the kernel changes to use the scoutfs_key struct as the btree key
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.

We had manually implemented a few of the functions to add values to
specific endian types. Make a macro to generate the function and
generate them for all the endian types we use.

Add support for reporting errors to data waiters via a new
SCOUTFS_IOC_DATA_WAIT_ERR ioctl. This allows waiters to return an error
to readers when staging fails.

It's handy to use ilog2 in the format header for defining shifts based
on values. Add a userspace helper that uses glibc's log2 functions.

Add support for initializing radix allocator blocks that describe free
space in mkfs and support for printing them out.

Add a scoutfs command wrapper around the statfs_moe ioctl. It's the
same as the stat_more ioctl but has different fields and a different
ioctl.

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.
