acpica: do not print warning for missing _ADR
Started seeing the following after updating to VMware ESXi 8.0:
pcib2: <ACPI Host-PCI bridge> on acpi0
pcib2: could not evaluate _ADR - AE_NOT_FOUND
pci2: <ACPI PCI bus> on pcib2
vmx0: <VMware VMXNET3 Ethernet Adapter> ...
The virtual NIC works fine, and the code comment suggests that
missing _ADR is not something fatal, skip printing the message
if status is AE_NOT_FOUND.

Correct several bugs in fsck_ffs(8) triggered by corrupted filesystems.
If a directory entry has an illegal inode number (less than zero
or greater than the last inode in the filesystem) the entry is removed.
If a directory '.' or '..' entry had an illegal inode number they
were being removed. Since fsck_ffs knows what the correct value is
for these two entries fix them rather deleting them.
Add much more extensive cylinder group checks and use them to be
more careful about rebuilding a cylinder group.
Check for out-of-range block numbers before trying to free them.
When a directory is deleted also remove its cache entry created
in pass1 so that later passes do not try to operate on a deleted
directory.
Check for ctime(3) returning NULL before trying to use its return.
When freeing a directory inode, do not try to interpret it as a
directory.
Reserve space in the inostatlist to have room to allocate a
lost+found directory.
If an invalid block number is found past the end of an inode simply
remove it rather than clearing and removing the inode.
Modernize the inoinfo structure to use queue(3) LIST rather than a
handrolled linked list implementation.

Before version 2.25, glibc's unistd.h would define the POSIX subset of
getopt.h by defining __need_getopt, including getopt.h (which would
disable the header guard) and then undefining it so later including
getopt.h explicitly would define the extensions. However, we wrap
getopt, and so the wrapper's #pragma once breaks that. Thus getopt.h was
included before the real unistd.h to ensure we get all the extensions.
However, with clang 12 that causes problems where we get a function
mismatch (since getopt can throw exceptions). If we include it after
unistd.h, it will get the full definitions since glibc no longer does
the subsetting thing. This will result in matching definitions and fix
clang 12.

Updates to UFS/FFS superblock integrity checks when reading a superblock.
Have to add a check that the computed cylinder group size does not
exceed the block size of the filesystem.
It is also necessary to validate additional parameters when a
superblock is going to be used in read-only mode if its supplementary
information is going to be read in to ensure that the size and
location of the supplementary information is valid. Also when a
warning is raised let it be accepted, but bound the flagged field

epair: Simplify the transmit path and address lost wakeups
epairs currently shuttle all transmitted packets through a single global
taskqueue thread. To hand packets over to the taskqueue thread, each
epair maintains a pair of ring buffers and a lockless scheme for
notifying the thread of pending work. The implementation can lead to
lost wakeups, causing to-be-transmitted packets to end up stuck in the
queue.
Rather than extending the existing scheme, simply replace it with a
linked list protected by a mutex, and use the mutex to synchronize
wakeups of the taskqueue thread. This appears to give equivalent or
better throughput with >= 16 producer threads and eliminates the lost
wakeups.

epair: Avoid loading m_flags into a short
The m_flags field of struct mbuf is 24 bits wide and so gets truncated
in a couple of places in the epair code. Instead of preserving the
entire flag set, just remember whether M_BCAST or M_MCAST is set.
sender_body() uses OPT_COPY to copy the frame into the destination slot
for the first 100,000 packets. Then it removes OPT_COPY to improve
performance. The function always starts with the first tx ring.
If multiple tx rings are in use, it is possible that the initial 100k
packets will only use the first ring. After OPT_COPY is removed, there
may come a time when the first ring is full and sender_body() will move
to the next ring which was never initialized. As a result it will send
all zero packets. (This was discovered when the receiving NIC reported
rx errors.)
Before any transmissions, step through every tx ring and set
NS_BUF_CHANGED on every slot. That will force send_packets() to
initialize the slot when first used. Since it only copies when
necessary, it performs better than always setting OPT_COPY. With this
change, there is no reason for the "drop copy" code.
