When a temporary/bootonce boot environment is renamed, we need to also
update the bootenv nvlist on-disk to reflect the new name. Additionally,
when a temporary/bootonce boot environment is destroyed, we also need to
clear out the on-disk state.

bsdlabel is intended to support up to 20 partitions, but the disklabel
struct has a d_partitions array with only BSD_NPARTS_MIN (8) entries.
Previously, an attempt to operate on a bsdlabel with more than eight
partitions resulted in a buffer overflow.
As a stopgap limit bsdlabel to 8 partitions until this is fixed
properly.

The usual use case in 2024 for newfs_msdosfs is creating filesystems on SD cards
for older hardware. In most tutorials, they call the cluster size "allocation
size". Therefore, add a small note next to cluster size that it is also called
allocation size, and add an example for how to do this.

The quota options are pseudo options and not passed to the mount system
call when a filesystem is mounted. They are not part of the info
returned from getmntinfo(3), so can't be printed. Add a note to this
effect.
Route destinations like 10/8 are most likely intended as a shorthand
for 10.0.0.0/8, but instead it means 0.0.0.10/8, which includes
only bits in the host part of the mask, and hence adds a route to
0.0.0.0/8. In 12.x, there was code to "do what I mean", which was
removed as part of a cleanup of old network class remnants. Given
that we have gone this long without that code, do not restore that
behavior. Instead, detect the issue and produce an error.
Specifically, if there are no dots in a numeric IPv4 address, the
mask is specified with CIDR notation (using a slash), and there are
bits set in the host part, produce an error like this for 10/8:
route: malformed address, bits set after mask; 10 means 0.0.0.10

Consumers of libpfctl can (and in future, should) open a handle. This
handle is an opaque object which contains the /dev/pf file descriptor
and a netlink handle. This means that libpfctl users can open the handle
as root, then drop privileges and still access pf.
Already add the handle to pfctl_startstop() and pfctl_get_creatorids()
as these are new in main, and not present on stable branches. Other
calls will have handle-enabled alternatives implemented in subsequent
commits.

Replace ieee80211_ie_vhtcap with ieee80211_vht_cap and
ieee80211_ie_vht_operation with ieee80211_vht_operation.
The "ie" version has the two bytes type/length at the beginning which
we did not actually use as such (the one place doing did just as unused
extra work).
Using the non-"ie" versions allows us to re-use them on shared code.
Using an enum helps us to not accidentally get unsuppored or unhandled
values tough we cannot use it in the struct as we need to ensure the
field width.
ieee80211_vht_operation is guarded by _KERNEL/WANT_NET80211. While the
header is supposed to be exported to user land historically, software
such as wpa bring their own structure definitions. For in-tree usage
it is only ifconfig which really cares (at least for now).

We recently noticed that the recursive printing of labels wasn't working
like the recursive printing of rules.
When running pfctl -sr -a* we get a listing of all rules, including the
ones inside anchors. On the other hand, when running pfctl -sl -a*, it
would only print the labels in the root level, just like without the
-a* argument.
As in our use-case we are interested on labels only and our labels are
unique even between anchors, we didn't add indentation or hierarchy to
the printing.

Various disk controllers require their buffers to be aligned to a
cache-line size (128 bytes). For buffers allocated in structures,
ensure that they are 128-byte aligned. Use aligned_malloc to allocate
memory to ensure that the returned memory is 128-byte aligned.
While we are here, we replace the dynamically allocated inode buffer
with a buffer allocated in the uufsd structure just as the superblock
and cylinder group buffers do.
This can be removed if/when the kernel is fixed. Because this problem
has existed on one I/O subsystem or another since the 1990's, we
are probably stuck with dealing with it forever.
