In el9 releases, our includes declare offsetof() before our header
chain includes stddef.h, which doesn't properly check if offsetof
is already defined, leading to a redefinition. Just include stddef
at all times here.

Move the code that checks that the super is in use from
change-format-version into its own function in util.c. We'll use it in
an upcoming command to change the quorum config.

We're adding another command that does block IO so move some block
reading and writing functions out of mkfs. We also grow a few function
variants and call the write_sync variant from mkfs instead of having it
manually sync.

Add macros for stringifying either the name of a macro or its value. In
keeping with making our utils/ sort of look like kernel code, we use the
kernel stringify names.

Support max-meta-size and max-data-size using KMGTP units with rounding.
Detect other fs signatures using blkid library.
Detect ScoutFS super using magic value.
Move read_block() from print.c into util.c since blkid also needs it.

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.

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.

scoutfs now directly uses the kernel dlm subsystem and offsers a debugfs
file with the current lock state. We don't need userspace to read and
format the contents of a debugging file.

This command takes a device and dumps all dlmglue locks and their state to
the console. It also computes some average lock wait times. We provide a
couple of options:
--lvbs=[yes|no] turns on or off printing of lvb data (default is off)
--oneline provides a more concise per-lock printout.
