The allows gcc + GNU ld to link programs with -m32 -pthread without
erroring out due to _umtx_op_err being undefined (unless -lsys is added
to the link command.
We now always link _umtx_op_err into libthr (not just when it's static)
and filter it with libsys so we call that implementation. The dynamic
implementations (at least the assembly ones) should likely become stubs
as a further refinement.

IERS is the source of truth for leap seconds. Their leapsecond file is
updated most quickly and is always right (unlike the IANA one which
often lags). IERS operates this public service for the express purpose
of random people downloading it. Their terms of service are compatible
with open source (we could include this in our release). Rather than
fighting with questions around this because the IANA one changed
locations or the auto update script broken, just use this.

As a separate commit, now move locore-v6.S to locore.S. This makes git

didn't save enough metadata for the converter to allow it to go back

no need for it here.

The regression affected ACPI-based systems without EFI poweroff support
(including VMs).
The key reason for the regression is that I overlooked that poweroff is
requested by RB_POWEROFF | RB_HALT combination of flags. In my opinion,
that command is a bit bipolar, but since we've been doing that forever,
then so be it. Because of that flag combination, the order of
shutdown_final handlers that check for either flag does matter.
Some additional complexity comes from platform-specific shutdown_final
handlers that aim to handle multiple reboot options at once. E.g.,
acpi_shutdown_final handles both poweroff and reboot / reset. As
explained in 9cdf326b4f, such a handler must run after shutdown_panic to
give it a chance. But as the change revealed, the handler must also run
before shutdown_halt, so that the system can actually power off before
entering the halt limbo.
Previously, shutdown_panic and shutdown_halt had the same priority which
appears to be incompatible with handlers that can do both poweroff and
reset.
The above also applies to power cycle handlers.

It resolves conflicts in several files that we have modified (but we can
likely fix the build system so we don't have to modify them since it's

empty #define.
It also deletes new files in the platform directory that are similar to
prior non-freebsd platform files we've deleted.

At runtime, when rtld loads libc it will also load libsys. For each
symbol that is present in both, the libsys one will override the libc
one. It continues to be the case that program need only link against
libc (usually implicitly). The linkage to libsys is automatic.

For libsys we need to expose all the private symbols (_ and __sys_
prefixes) so libsys can replace the libc versions. Rather than trying
to maintain a table, teach makesyscalls to generate it.
There are a small number of "_" prefixed symbols that are exposed as
public interfaces rather than in the private symbol space. Since the
list is short, just hardcode it for now.
If doesn't appear that we need to export freebsd#_foo symbols for compat
system calls explicitly. If it turns out we do, there are probably few
enough of them to handle seperately.
