This additional socket was created in 2e89951b6f and 240d5a9b1c
to try workaround problems with classic PF_UNIX/SOCK_DGRAM sockets.
With recent changes in kernel this trick is no longer needed, so the
trick can be reverted.
In syslogd(8) we would still create the socket for the next several
major releases for compatibility.

The "/dev/log" socket existed in pre-FreeBSD times. Later it was
substituted to a compatibility symlink. The symlink creation was
deprecated in FreeBSD 10.2 and 9-STABLE.

This avoids relying on the `includes` target to generate this header
which must be in .OBJDIR for the ncurses library to find it.
With an upcoming change libcompat build won't build a seperate
sysroot and will instead share with the 64-bit target which means the
`includes` target will not be called.

Enhanced REP MOVSB feature of CPUs starting from Ivy Bridge makes
REP MOVSB the fastest way to copy memory in most of cases. However
Intel Optimization Reference Manual says: "setting the DF to force
REP MOVSB to copy bytes from high towards low addresses will expe-
rience significant performance degradation". Measurements on Intel
Cascade Lake and Alder Lake, same as on AMD Zen3 show that it can
drop throughput to as low as 2.5-3.5GB/s, comparing to ~10-30GB/s
of REP MOVSQ or hand-rolled loop, used for non-ERMS CPUs.
This patch keeps ERMS use for forward ordered memory copies, but
removes it for backward overlapped moves where it does not work.
This is just a cosmetic sync with kernel, since libc does not use
ERMS at this time.

Commit e0e0323354 removed compat stubs for

removed the documentation for them in the manual page only partially.

It is recommended by Intel to use fixed counters when possible to
leave programmable ones for different events.
This fixes `pmc stat`, which tries to count 6 events same time, while
many Intel CPUs have only 4 programmable counters.

Some of the sanitizers from compiler-rt can use ignore lists, which are
loosely modeled on valgrind's example. Upstream provides default lists
for AddressSanitizer, CFI, and MemorySanitizer, so install these in the
expected location, /usr/lib/clang/14.0.3/share.

According to pam_exec(8), the `expose_authtok` option should be ignored
when the service function is `pam_sm_setcred`. Currently `pam_exec` only
prevent prompt for anth token when `expose_authtok` is set on
`pam_sm_setcred`. This subsequently led to segfault when there isn't an
existing auth token available.
Bug reported on this: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=263893
After reading https://reviews.freebsd.org/rS349556 I am not sure if the
default behaviour supposed to be simply not prompt for authentication
token, or is it to ignore the option entirely as stated in the man page.
This patch is therefore only adding an additional NULL check on the item
`pam_get_item` provide, and exit with `PAM_SYSTEM_ERR` when such item is
NULL.

1. Merge LLVM's 315d792130258a9b7250494be8d002ebb427b08f, adding support
for FreeBSD/powerpc64*.
2. Add sanitizer list to lib/libclang_rt/Makefile, taken from the list of
libraries that llvm-devel port builds.
3. powerpc64le supports the same sanitizers that powerpc64, but powerpc64le
also supports xray* sanitizers.
4. lib/libclang_rt/xray/Makefile hardcodes amd64-specific files, so that needs
to be conditionalized.
5. Sanitizers are not enabled for powerpc, because powerpc supports only

[libc++] Define `namespace views` in its own detail header.
Discovered in the comments on D118748: we would like this namespace
to exist anytime Ranges exists, regardless of whether concepts syntax
is supported. Also, we'd like to fully granularize the <ranges> header,
which means not putting any loose declarations at the top level.
