Most consumers of g_metadata_store were passing in partially unallocated
memory, resulting in stack garbage being written to disk labels. Fix them by
zeroing the memory first.
gvirstor repeated the same mistake, but in the kernel.
Also, glabel's label contained a fixed-size string that wasn't
initialized to zero.

Specifically reading is done if ffs_sbget() and writing is done
in ffs_sbput(). These functions are exported to libufs via the
sbget() and sbput() functions which then used in the various
filesystem utilities. This work is in preparation for adding
subperblock check hashes.
No functional change intended.

calculation of the cylinder-group check hash in fsck_ffs.

Make it possible to retrieve mmc parameters via the XPT_GET_ADVINFO
call instead. Convert camcontrol to the new scheme.

check-hash after making changes to the cylinder group. The problem
was that the journal-recovery code was calling the libufs bwrite()
function instead of the cgput() function. The cgput() function updates
the cylinder-group check-hash before writing the cylinder group.
This change required the additions of the cgget() and cgput() functions
to the libufs API to avoid a gratuitous bcopy of every cylinder group
to be read or written. These new functions have been added to the
libufs manual pages. This was the first opportunity that I have had
to use and document the use of the EDOOFUS error code.

When the fsck_ffs program cannot fully repair a file system, it will
output the message PLEASE RERUN FSCK. However, it does not exit with a
non-zero status in this case (contradicting the man page claim that it
"exits with 0 on success, and >0 if an error occurs." The fsck
rc-script (when running "fsck -y") tests the status from fsck (which
passes along the exit status from fsck_ffs) and issues a "stop_boot"
if the status fails. However, this is not effective since fsck_ffs can
return zero even on (some) errors. Effectively, it is left to a later
step in the boot process when the file systems are mounted to detect
the still-unclean file system and stop the boot.
This change modifies fsck_ffs so that when it cannot fully repair the
file system and issues the PLEASE RERUN FSCK message it also exits
with a non-zero status.
While here, the fsck_ffs man page has also been updated to document
the failing exit status codes used by fsck_ffs. Previously, only exit
status 7 was documented. Some of these exit statuses are tested for in
the fsck rc-script, so they are clearly depended upon and deserve
documentation.

The original bug describes it best:
When an absolute time is specified to shutdown, the program's
behavior depends on whether that time has passed during the
current calendar day. POLA would suggest that for shutdown,
whose time argument is always supposed to be in the future,
absolute times specified without a specific date should refer
to the next occurrence of that time, rather than erroring out
if that time has already passed during the current day.

we started diverging.
Further relaxation of the licensing terms are possible after we
check the NetBSD updates, and contact the local authors.
In the case of ccdconfig.8 this reinstates the 3rd clause but since the
code is not directly from Berkeley, the change was bogus.

After consultation with SPDX experts and their matching guidelines[1],
the licensing doesn't exactly match the BSD-2-Clause. It yet remains to be
determined if they are equivalent or if there is a recognized license that
matches but it is safer to just revert the tags.
Let this also be a reminder that on FreeBSD, SPDX tags are only advisory
and have no legal value (but IANAL).
