mount(8): Avoid truncation when fstab-formatting unionfs mount info
When displaying unionfs mounts in fstab format (`mount -p`), mount(8)
currently uses strlcpy to remove the disposition prefix from the mount
name returned by getmntinfo(3). But strlcpy, like strcpy before it,
does not guarantee correct behavior if the source and destination
buffers overlap.
Just offset the buffer and avoid the destructive copy in the first
place.

pci: avoid accidental clobbering of regs on some fdt platforms
Most pci controllers will just have a single reg for the config space,
but others (e.g., on Apple Silicon) may have more following that to
describe, e.g., controller port space. Bump the "ranges" rid space up
to avoid overriding these other memory resources.

ping: adjust error messages and comments for -gGh flags
The -gGh flags are used for sweep ping to specify minimal,

ping: correct minimal payload size for the sweep ping
The -g flag specifies a minimal payload size for the sweep ping

exports.5: Document the current behavior of -alldirs
Commit 07cd69e272da adds a new "-a" mountd option,
which changes the behavior of mountd when file systems
are exported via -alldirs.
This patch updates the man page to reflect the actual
behavior when -alldirs is used when mountd is started
with/without -a. Prior to the above commit, exports(5)
documented that, when -alldirs was specified, the exports
line would fail unless the directory was a server file
system mount point. This behavior was only documented
in the Examples section and has not been implemented
since a change between FreeBSD 1 and FreeBSD 2 was done.
This is a contents change.

mountd.c: Define a new -a command line option
Bugzilla PR#282995 reported that, when a file system was
exported with the "-alldirs" flag, the export succeeded even
if the directory path was not a server file system mount point.
This behaviour for "-alldirs" was only documented in the
Example section of exports(5) and had not been enforced
since FreeBSD2. (A patch applied between FreeBSD1 and
FreeBSD2 broke the check for file system mount point.)
Since the behaviour of allowing the export has existed since
FreeBSD2, the concensus on a mailing list was that it would
be a POLA violation to change it now.
Therefore, this patch adds a new "-a" mountd command line
option to enforce a check for the exported directory being a
server file system mount point.
