Summary:
This change moves /usr/bin/cpuset to /bin/cpuset so it is more readily
available on hosts where the /usr partition might not be mounted at the
time / has been mounted.
Remove some complexity from rc.subr(8) since /bin is assumed to always
be present if/when / is mounted.

Test Plan:
- Test out rc.subr change.
- Confirm that the installation logic does what's needed.
Relnotes: yes (moving cpuset may impact strict file permissions/mode checking)

As of pytest 7.4 it no longer walks all the way to the root directory
of the file system to find conftest files. As a result we don't find /
usr/tests/conftest.py, and don't load atf_python. That in turn causes
atf_python tests to fail.

Historically, tftpd disallowed write requests to existing files
that are not publicly writable. Such requirement is questionable at least.
Let us make it possible to run tftpd in chrooted environment
keeping files non-world writable.
New option -S enables write requests to existing files
for chrooted run according to generic file permissions.
It is ignored unless tftpd runs chrooted.

With ifunc based SIMD dispatch, we cannot use the amd64 assembly
implementations of string functions. Modify rtld to instead use
the generic functions. To avoid an architecture-specific special
case, this change is applied to all architectures.

For instance, dso might be mapped as needed but not yet initialized from
the other subtree of needed objects, while current object' constructor
does dlopen() for the dso. Right now rtld does relocations and other
processing based on the arrival of new objects in the global list, which
is not happens there. Directly check for the initialization state of
the object, for which we would return the handle.
One practical use case of this support is e.g. dlopen("libthr.so",
RTLD_NOLOAD) by libraries that are threading-aware but happy to live
with libc pthread shims if the program is not multithreaded.

Add a stop indicator to rtld_start to satisfy unwinders:

If a Return Address register is defined in the virtual unwind table,

there is no return address and no call address, and the virtual

We have somewhat twisted logic to determine actions for dumpdev
considering three sources of information:
* kenv "dumpdev" tunnable supposed to point to specific device;
* /etc/defaults/rc.conf "dumpdev" variable;
* /etc/rc.conf that may be unset or set to "NO", "AUTO" or device name.
For CURRENT without any setting in kenv or /etc/rc.conf
the default is "AUTO". For STABLE branches the default is "NO".
Current implementation breaks for STABLE branches if kenv points
to specific device but /etc/rc.conf does not set "dumpdev" at all.
Let us fix it commenting out "dumpdev" in /etc/defaults/rc.conf
for STABLE branches and making the code to consult kenv
if "dumpdev" is not set elsewhere.

As of "8cb16fdbea6b Restore original frequency on exit.", powerd
restores the original frequency itself.
Further, if the original frequency is not the same as the
first frequency found in the frequency list, then the restoration
done by the powerd_poststop will restore the wrong frequency.
This can happen on Intel machines where Turbo is not enabled,
but the turbo frequency is first in the list of frequencies.
In this case, turbo will be enabled when the user did not want
it to be.

has IPv6 enabled, this means unconditionally sleeping, even on systems
