<sys/time.h>: Add 3rd arg to timespecadd()/sub() and make them public.

* Switch to the three argument versions of the timespecadd() and
timespecsub() macros. These are now the predominant ones. FreeBSD,
OpenBSD, NetBSD, and Solaris (albeit only for the kernel) have them.

* Make those macros public too. This allows for a number of cleanups
where they were defined locally.

kernel - Add a global priority hack for ACPI

* Allows ACPI to fully probe and attach all acpi devices before
attaching any non-ACPI devices.

* May improve device attach stability.

* Currently only implemented at the top-level of the acpi
device tree.

acpi - Incidental MPSAFE (2)

* The changes in a639f788 revealed bubgs in acpi_thermal's support
threads. These threads start executing before the main acpi device
finishes its attach. The mplock serialization saved us before, and
removing it revealed the problem.

* Force serialization using the main acpi lock to prevent the support
threads from starting up until after the main acpi attach has
completed.

acpi - Incidental MPSAFE

* Make ACPI devices MPSAFE (use a private token).

* Make the ACPI interupt MPSAFE.

kernel/acpica: In notify handlers, always report on unknown notifies.

Also, make the messages more uniform.

kernel/acpi_thermal: Fix comment typo.

meaninglessly large values of more than 3600s.

meaninglessly large values of more than 3600s.

* Wake up the acpi_tz_thread after changing hw.acpi.thermal.polling_rate,
to wake it up when hw.acpi.thermal.polling_rate was set to 0 (i.e.
disabled polling) or a very large value before.

kernel/acpi_thermal: If the _TMP can't be evaluated, increase the interval.

If _TMP evaluation fails two times, switch to trying every two hours.
I think eventually we should move to stop reading the sensor at all
(it is usually a bug in the AML and won't spring to life again all
of a sudden), but for now, this lowers the burden on log files.

kernel/acpi: Add missing ACPI_LOCK_INIT in acpi_thermal.

kernel: Refer to it as "ACPICA", not "ACPI CA" or "ACPI-CA".

kernel/acpi: Sync acpi_thermal with FreeBSD.

kernel: Use DEVMETHOD_END in the drivers.

kernel: Move sys/dev/acpica5 to sys/dev/acpica.

The 5 used to indicate that it was imported from FreeBSD 5 but that
doesn't matter anymore.

Misc cleanups to take care of GCC3.x warnings. Missing 'U' and 'LL'
postfixes on large unsigned or 64 bit constants, non-storage structural
declarations embedded in structures, deprecated use of __FUNCTION__,
missing 'break' statements in the last switch case, goto label ops where
the label occurs just before an end-brace (many of which appear to be
fixable with 'break' or 'continue' instead and existed simply due to
programmer-paranoia), garbage data in #endif lines that was not commented
out. GCC3 also caught some argument count issues in kernel printfs.

Many of these (obvious) fixes are similar to or copied from 5.x.

Also fix a few other minor issues such as certain drivers declaring a
proc pointer instead of a thread pointer.

Move -ffreestanding from CWARNFLAGS to CFLAGS. It doesn't belong in
CWARNFLAGS.

* OSPM ACPI driver. Note that this driver does not include
support for PCI interrupt routing or enumeration of ISA bridges or
Host to PCI bridges. While functional on some machines, this driver
should be considered experimental and should be tested prior to being
deployed in a production environment.
