Update the NetBSD Kernel Concurrency Sanitizer (KCSAN) runtime to work in
the FreeBSD kernel. It is a useful tool for finding data races between
threads executing on different CPUs.
This can be enabled by enabling KCSAN in the kernel config, or by using the
GENERIC-KCSAN amd64 kernel. It works on amd64 and arm64, however the later
needs a compiler change to allow -fsanitize=thread that KCSAN uses.

11541 allocation_classes feature must be enabled to add log device
illumos/illumos-gate@c1064fd7cec1064fd7cehttps://www.illumos.org/issues/11541
After the allocation_classes feature was integrated, one can no longer add a
log device to a pool unless that feature is enabled. There is an explicit check
for this, but it is unnecessary in the case of log devices, so we should handle
this better instead of forcing the feature to be enabled.

FreeBSD notes.
I faithfully added the new -g, -L, -P flags, but only -g does something:
vdev GUIDs are displayed instead of device names. -L, resolve symlinks,
and -P, display full disk paths, do nothing at the moment.
The use of special vdevs is backward compatible for read-only access, so
root pools should be bootable, but exercise caution.

r354290 removed arm.arm from universe, but arm.arm kernels were still
found and built during the kernel stage. I'm not aware of a better way
to address this at the moment, but since there aren't many arm.arm
kernels anyhow just add an explicit NO_UNIVERSE to them.

Later parts assume that this would've been done if interrupts are enabled,
but this is the only case in which that wouldn't have been true. This commit
also reorders operations such that we're done touching slot/slot->intmask
before we call back into the SDHCI framework and exit.
r354823 kicked DATA_END handling out of the DMA interrupt path "to make
things easy", but this was likely a mistake -- if we know we're done after
we've finished pending DMA operations, we should go ahead and acknowledge
it rather than waiting for the controller to finalize it. If it's not ready,
we'll simply re-enable interrupts and wait for it anyways, to be re-entered
in sdhci_data_intr.

Add code to decode the BootCurrent and BootXXXX variable it points at
to deduce the ESP used to boot the system. By default, it prints the
path to that device. With --unix-path (-p) it will instead print the
current mount point for the ESP, if any (or an error). With
--device-path (-d) it wil print the UEFI device path for the ESP.
Note: This is the best guess based on the UEFI variables. If the ESP
is part of a gmirror, etc, that won't be reported. If by some weird
chance there was a complicated series of chain boots, this may not be
what you want. For setups that don't add layers on top of the raw
devices, it is accurate.

Each boot, regenerate /var/run/os-release based on the currently running
system. Create a /etc/os-release symlink pointing to this file (so that this
doesn't create a new reason /etc can not be mounted read-only).
This is compatible with what other systems do and is what the sysutil/os-release
port attempted to do, but in an incomplete way. Linux, Solaris and DragonFly all
implement this natively as well. The complete standard can be found at
https://www.freedesktop.org/software/systemd/man/os-release.html
Moving this to the base solves both the non-standard location problem with the
port, as well as the lack of update of this file on system update.

Mount the UEFI ESP on /boot/efi. No current system uses this by default, but
there are many ad-hoc schemes that do this in /efi or /esp or /uefi and adding a
new directory at the top-level would have a much higher likelihood of
collision. Document this in /etc/mtree/BSD.root.mtree and create EFIDIR and
related variables in bsd.own.mk.

Disable it by default for now, with the expectation that it will be

In r339216 a privsep wrapper was added for login_getpwclass to address
PR 231172. Unfortunately the change used the MON_AUTH flag in the
wrapper, and MON_AUTH includes MON_AUTHDECIDE which triggers an
auth_log() on each invocation. getpwclass() does not participate in the
authentication decision, so should be MON_ISAUTH instead.

KCSAN is a tool to find concurrent memory access that may race each other.
After a determined number of memory accesses a cell is created, this
describes the current access. It will then delay for a short period
to allow other CPUs a chance to race. If another CPU performs a memory
access to an overlapping region during this delay the race is reported.
This is a straight import of the NetBSD code, it will be adapted to
FreeBSD in a future commit.

Currently si_usecount is effectively a sum of usecounts from all associated
vnodes. This is maintained by special-casing for VCHR every time usecount is
modified. Apart from complicating the code a little bit, it has a scalability
impact since it forces a read from a cacheline shared with said count.
There are no consumers of the feature in the ports tree. In head there are only
2: revoke and devfs_close. Both can get away with a weaker requirement than the
exact usecount, namely just the count of active vnodes. Changing the meaning to
the latter means we only need to modify it on 0<->1 transitions, avoiding the
check plenty of times (and entirely in something like vrefact).

Typical reasons for doublefault faults are either kernel stack
overflow or bugs in the code that manipulates protection CPU state.
The later code is the code which often has to set up gsbase for
kernel. Switching to explicit load of GSBASE MSR in the fault handler
makes it more probable to output a useful information.
Now all IST handlers have nmi_pcpu structure on top of their stacks.
It would be even more useful to save gsbase value at the moment of the
fault. I did not this because I do not want to modify PCB layout now.
