fusefs: Implement support for the auto_unmount option kernel-side
libfuse clients may pass the "-o auto_unmount" flag to ensure that the mountpoint
will get unmounted even if the server terminate abnormally. Without this flag
sending KILL to a FUSE daemon leaves its mountpoint mounted.

ng_netflow v9: fix template re-announcement using packet count
Increment fe->sent_packets after export9_send().
Previously, NetFlow v9 templates were only re-announced based on
time, ignoring the packet count parameter (`templ_packets`).

nanobsd: Use mtree -C to produce the metalog
Prefer an mtree -C output, which is guaranteed to be mtree-compatible.
Add "gname", "uname", and "tags" to the default keyword set, while
removing "size" and "time", the latter being set on kernel file entries
and taking precedence over makefs -T (when paired with -F).
As a side effect, this produces a cleaner file with sorted keywords.
Note that passing "-u" to sort in order to pipe to mtree is no longer
necessary, but we'll do it out of habit.

amd64: Fix sys/pcpu.h usage in vmm_host.h and md_var.h
Include sys/pcpu in vmm_host.h as its structs and functions are used
there, and add a forward declaration of struct pcpu to md_var.h as it
is used in some function prototypes.

nfsd: Fix handling of hidden/system during Open/Create
When an NFSv4.n client specifies settings for the archive,
hidden and/or system attributes during a Open/Create, the
Open/Create fails for ZFS. This is caused by ZFS doing
a secpolicy_xvattr() call, which fails for non-root.
If this check is bypassed, ZFS panics.
This patch resolves the problem by disabling va_flags
for the VOP_CREATE() call in the NFSv4.n server and
then setting the flags with a subsequent VOP_SETATTR().
This problem only affects FreeBSD-15 and main, since the
archive, system and hidden attributes are not enabled
for FreeBSD-14.
I think a similar problem exists for the NFSv4.n
Open/Create/Exclusive_41, but that will be resolved
in a future commit.
