Make offset and length optional. Allow size units (KMGTP) to be used
for offset/length.
release: Since off/len no longer given in 4k blocks, round offset and
length to to 4KiB, down and up respectively. Emit a message if rounding
occurs.
Make version a required option.
stage: change ordering to src (the archive file) then the dest (the
staged file).

Implement a fallback mechanism for opening paths to a filesystem. If
explicitly given, use that. If env var is set, use that. Otherwise, use
current working directory.
Use wordexp to expand ~, $HOME, etc.

Now that we're in one repo utils can get its format and ioctl headers
from the authoriative kmod files. When we're building a dist tarball
we copy the files over so that the build from the dist tarball can use
them.

Not initializing wid[] can cause incorrect output.
Also, we only need 6 columns if we reference the array from 0.

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.

It was too tricky to pick out the difference between metadata and data
usage in the previous format. This makes it much more clear which
values are for either metadata or data.

dev.c includes linux/fs.h which includes linux/types.h, which defines
these types, __be16 etc. These are also defined in sparse.h, but I don't
think these are needed.
Definitions in linux/types.h includes stuff to set attr(bitwise) if
__CHECKER__ is defined, so we can remove __sp_biwise.

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.

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

The calculation of the last valid data blkno was off by one. It was

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
