`MK_ZONEINFO_LEAPSECONDS_SUPPORT == yes` and
`MK_ZONEINFO_OLD_TIMEZONES_SUPPORT == yes`.
Keep `LEAPSECONDS` and `OLDTIMEZONES` for backwards compatibility,
but print out a warning notifying users that they should use the new
variables, in an effort to migrate them to the variables. This is being
done mostly for automated build tools, etc, that might rely on these
variables being set. The variables will be removed in the future on
^/head, e.g., after ^/stable/12 is cut.

After the addition of SUBDIR.yes, uniquifying/ordering the SUBDIRs doesn't
make a whole lot of sense, and it's in effect a half measure.
Ordering SUBDIR (after adding SUBDIR.yes to it) in bsd.subdir.mk is a
separate change that warrants more discussion/testing, because while
the SUBDIR_PARALLEL work largely fixed dependency ordering for SUBDIRs,
there might be downstream FreeBSD consumers that rely on the SUBDIR
ordering.

This patch adds support for AF_LOCAL socket upcalls to an nfsuserd daemon
that supports them. A future patch to the nfsuserd daemon will use AF_LOCAL
sockets to avoid a problem when using upcalls to 127.0.0.1 if jails are
in use.

This addresses a deadlock during boot when EARLY_AP_STARTUP is configured:
a taskqueue thread may call pause() with an ACPI mutex held, and thread0
may block on this mutex before configuring the eventtimer. In this case
the taskqueue thread will sleep forever waiting for its callout to fire.

ZFS SLOGs have very specific access pattern with many cache flushes,
which none of benchmarks I know can simulate. Since SSD vendors rarely
specify cache flush time, this measurement can be useful to explain why
some ZFS pools are slower then expected. This test writes data chunks
of different size followed by cache flush, alike to what ZFS SLOG does,
and measures average time.
To illustrate, here is result for 6 years old SATA Intel 710 Series SSD:

While the first one obviously has maximal throughput limitations, the
second one has so high cache flush latency (about 2 millisecond), that
it makes one almost useless in SLOG role, despite of its good throughput
numbers. Power loss protection is out of scope of this test, but I
suspect it can be related.

Even though gdb and kgdb may not be removed for 12.0 on some architectures,
the notice is unconditional as these tools will likely be removed at some

Raspberry Pi. It doesn't affect cases where the terminal size is
already non-zero, such as SSH or vt(4) sessions.
Note that this doesn't handle a scenario pointed out by rgrimes@:
when the terminal is resized after login, the terminal size won't
get updated even after logging out and back in.

When INVARIANTS is set the union where the two uninitialized fields
reside gets properly zeroed. This patch ensures the two uninitialized
fields are zeroed when INVARIANTS is undefined.
For 64-bit platforms this issue was not visible because so->sol_upcall
which is uninitialized overlaps with so->so_rcv.sb_state which is
already zero during soalloc();
For 32-bit platforms this issue was visible and resulted in an invalid

during soalloc().
Verifying the offset locations mentioned above are identical is left
