wc(1)'s slow path for counting words or multibyte characters requires
conversion of the 8-bit input stream to wide characters. However, a faster
path can be used for counting only lines ('-l' -- newlines have the same
representation in all supported encodings) or bytes ('-c').
The existing line count optimization was not used if the input was the
implicit stdin. Additionally, it wasn't used if only byte counting was
requested. This change expands the fast path to both of these scenarios.
Expanding the buffer size from 64 kB helps reduce the number of read(2)
calls needed, but exactly what impact that change has and what size to
expand the buffer to are still under discussion.

This commit defines some macros used by the pNFS server code.
They will not be used until the main pNFS server code merge occurs,
which will probably be in April 2018.
rc.conf(5) documents the gifconfig_<interface> keyword, which is
no longer implemented. Document the replacement, which works with
cloned_interfaces as well.

Improve options handling and error out if multiple mutually exclusive
options are passed to acpiconf. Switch from using atoi() to strtol() for
argument parsing, and add error checking and handling, instead of blindly
trusting that the integer conversion is OK.
Cange err() to errx() in once case, the errno value was garbage there.

r292392 modified the active queue scan to weigh clean pages differently
from dirty pages when attempting to meet the inactive queue target. When
r306706 was merged into the PQ_LAUNDRY branch, this mechanism was
broken. Fix it by scalaing the correct page shortage variable.

FFS performs asynchronous inode initialization, using a barrier write
to ensure that the inode block is written before the corresponding
cylinder group header update. Some GEOMs do not appear to handle
BIO_ORDERED correctly, meaning that the barrier write may not work as
intended. The sysctl allows one to work around this problem at the
cost of expensive file creation on new filesystems. The default
behaviour is unchanged.

shell scripts in scripts don't need
to be chmod +x to work. In fact most are not.
Of the tests I found from a simple search:
65 are chmod +x
84 are chmod -x
simply disable the check for test shell scripts.
efibootmgr manages the UEFI BootXXXX variables that implement the UEFI
Boot Manager protocol defined in the UEFI standards. It is modeled
after the Linux program of the same name with a mostly compatible set
of command line options. Since there's a fair amount of OS specifioc
code due to differeing names and methods of doing things, the
compatibility isn't 100%.
Basic functionality is implemented, though the more advanced next boot
functionality that's been defined elsewhere is unimplemented.

Now that the POSIX working group is going to require that basename(3)
and dirname(3) are thread-safe in future revisions of the standard,
there is even less of a need to provide basename_r(3). Remove this
function to prevent people from writing code that only builds on
FreeBSD and Bionic.
Removing this function seems to break exactly one port: sbruno@'s
qemu-user-static. I will send him a pull request on GitHub in a bit.
__FreeBSD_version will not be bumped, as any value from 2017 can be used
to test for the presence of a thread-safe basename(3)/dirname(3).

it would modify the mbuf using m_append(). Instead, call m_dup() and

This was done in 32-bit mode, but not duplicated when 64-bit mode was
brought in. Without this, stale mappings can be left, leading to odd
crashes when the wrong VA is checked in XX_PhysToVirt() (dpaa(4)).
layer, for example, to specify that the EFI boot partition should be
mounted at /efi and formatted normally with newfs_msdos rather than
splatted to from /boot/boot1.efifat.
This commit adds only the API for this; actual platform use will come later.
This option was used in the early days to allow performance measurements
extrapolating the use of SCTP checksum offloading. Since this feature
is now available, get rid of this option.
This also un-breaks the LINT kernel. Thanks to markj@ for making me
aware of the problem.
These were made redundant in r325841.

When more than one thread enters ufsdirhash_create() for the same
directory and the inode dirhash is instantiated, but the dirhash' hash
is not, all of them lock the dirhash shared and then try to upgrade.
Since there are several threads owning the lock shared, upgrade fails
and the same attempt is repeated, ad infinitum.
To break the lockstep, lock the dirhash in exclusive mode after the
failed try-upgrade.
