When the NFSv4.2 server does a VOP_ALLOCATE(), it needs
the operation to be done for the RPC's credential and not
td_ucred. It also needs the writing to be done synchronously.
This patch adds "ioflag" and "cred" arguments to VOP_ALLOCATE()
and modifies vop_stdallocate() to use these arguments.
The VOP_ALLOCATE.9 man page will be patched separately.

Add an assertion to unionfs_node_update() that the upper vnode is
exclusively locked; we already make the same assertion for the lower
vnode.
Also, assert in unionfs_noderem() that the vnode lock is not recursed
and acquire v_lock with LK_NOWAIT. Since v_lock is not the active
lock for the vnode at this point, it should not be contended.
Finally, remove VDIR assertions from unionfs_get_cached_vnode().
lvp/uvp will be referenced but not locked at this point, so v_type
may concurrently change due to vgonel(). The cached unionfs node,
if one exists, would only have made it into the cache if lvp/uvp
were of type VDIR at the time of insertion; the corresponding
VDIR assert in unionfs_ins_cached_vnode() should be safe because
lvp/uvp will be locked by that time and will not be used if either
is doomed.

Previously we would only search for a PHY xref in node of the miibus
parent.
That didn't work very well with switches.
Fix that by searching through "ports" subnode, checking if any of its
children have a valid PHY xref.
Since switches tend to have multiple ports we also have multiple
candidates.

AES-CBC OpenSSL assembly is used underneath.
The glue layer(ossl_aes.c) is based on CHACHA20 implementation.
Contrary to the SHA and CHACHA20, AES OpenSSL assembly logic
does not have a fallback implementation in case CPU doesn't
support required instructions.
Because of that CPU caps are checked during initialization and AES
support is advertised only if available.
The feature is available on all architectures that ossl supports:
i386, amd64, arm64.
The biggest advantage of this patch over existing solutions
(aesni(4) and armv8crypto(4)) is that it supports SHA,
allowing for ETA operations.

The SanDisk SD8SB8U1 and likely others pad their serial number with
spaces on the end rather than the start (at least when connected to a
SAS3008). This makes them difficult to wire unit numbers to with the
serial because you have to specify the trailing spaces. Instead, strip
out the trailing spaces.
We already strip leading spaces both here. In addition, when glabel
creates the devfs device nodes, leading and trailing spaces are removed
already (so there will be no change there either).

For scsi, ata and nvme, at least, we read a serial number from the
device (if the device supports it, some scsi drives do not) and record
it during the *_xpt probe device state machine before it posts the
AC_FOUND_DEVICE async event. For mmc, no serial number is ever
retrieved, so it's always NULL. Add the ability to match this serial
number during device wiring.
This mechanism is competely optional, and often times using a label
and/or some other attribute of the device is easier. However, other
times wiring a unit to a serial number simplifies management as most
monitoring tools require the *daX device and having it stable from boot
to boot helps with data continuity. It can be especially helpful for
nvme where no other means exists to reliably tie a ndaX device to an
underlying nvme drive and namespace.
A similar mechanism exists in Linux to mange device unit numbers with
udev.

Upstream one-true-awk has two sets of tests. These are in addition to
NetBSD's tests we're using. The 'bugs-fixed' tests from upstream are
ready to use as-is (more or less). However, the 'tests' from upstream
are not, so for now we'll just use the netbsd and bugs-fixed tests.
They provide an OK workout and are better than nothing, though the tests
themselves are for specific esoteric things.
The upstream bugs-fixed tests are *ALMOST* a drop in. However, 3 test
for errors and the upstream test jig mashes stdout and stderr together,
which atf doesn't do, so make a tiny tweak to the upstream tests that I
hope to upstream. Plus upstream has ../a.out: instead of awk: in the
output. Not sure how to deal with this yet, so I've not proposed
anything upstream and have changed the test locally.
In addition, the system-status.awk test is not suitable to run in ATF.
It wants to force sh to dump core, but kyua doesn't seem to allow that
sometimes so the test will fail or pass based on whether or not a core
dump can be created. Since it's unstable, remove it.
This required moving the netbsd tests to a new direcotry, so update
mtree files as well. The change is useless for 'make check' without it.
