yes: fix argv test race between fork and exec
The argv test checks ps(1) output immediately after backgrounding yes(1), but
the forked child briefly shows the parent shell's argv before exec(2) replaces it.
This caused intermittent failures where ps(1) captured the atf shell wrapper
command line instead of "yes y".

packages: Fix build with libucl 0.9.3
In libucl 0.9.3, macros and includes are disabled by default when
creating a new UCL parser. This breaks the package build, which
relies on includes. Fix this by explicitly passing zero flags
to ucl.parser().

fmax.3: Add caveat for going beyond C std requirements
libm's fmax and fmin family of functions treat +0.0 as greater than
-0.0. This is not required by the C standard, so the user may not see
this behaviour due to compiler optimization.

nfsid.h: Put the nfsd_idargs structure in a new .h
This patch moves the definition of the nfsd_idargs
structure out of nfs.h and into a new file called
nfsid.h.
This is being done so that it can be included in
nfs_diskless.c in a future commit.
There should be no semantics change from this
commit.

snd_uaudio: Retire sndcard_func usage
This is effectively a no-op, as it does not make use of the
sndcard_func->varinfo field, so eventually ua_probe() always succeeds.
Also change ua_probe()'s value to 0. There is no need to return
BUS_PROBE_DEFAULT, because snd_uaudio() attaches the sound(4)'s children
with bus_attach_children().

net: Add SIOCGI2CPB ioctl & add page/bank fields to ifi2creq
This commit adds page & bank fields to ifi2creq in preparation
for adding CMIS support for 400g optics to ifconfig.
The new ioctl SIOCGI2CPB is added, so that drivers can distinguish
between callers asking for page/bank selection and legacy callers
that simply failed to zero out all ifi2creq fields.
The mlx5en(4) driver and iflib(4) driver frameork have been updated
to use this new SIOCGI2CPB ioctl and support page/bank operations.
A follow-on patchset will add support to ifconfig for reporting
data from CMIS optics.
This has been tested on Nvidia ConnectX-7 and Broadcom Thor2 (using
out of tree driver) based NICs.

nfs_diskless: Add support for an NFSv4 root fs
Without this patch, diskless root NFS file systems
could only be mounted via NFSv3 (or NFSv2).
This patch adds the basic support needed to mount
a root fs via NFSv4.
At this time, the NFSv4 mount will only work if
the following is done on the NFS server configuration:
- The root directory specified in the "V4:" line in
/etc/exports must be "/". This is needed since the
path to mount must be the same for NFSv3 and NFSv4.
- The NFS server must be configured to do both NFSv3
and NFSv4, since the bootstrap code still uses NFSv3.
- The NFSv4 server must be configured with:
vfs.nfs.enable_uidtostring=1
vfs.nfsd.enable_stringtouid=1
since the NFSv4 root fs cannot be running nfsuserd(8)
when it is booting. (This limitation may be removed
