Sync ACPICA with Intel's version 20161222.

* Fixed a regression where occasionally a valid resource
descriptor was incorrectly detected as invalid at runtime,
and a AE_AML_NO_RESOURCE_END_TAG was returned.

* Fixed a problem with the recently implemented support that
enables control method invocations as Target operands to
many ASL operators. Warnings of this form: "Needed type
[Reference], found [Processor]" were seen at runtime for
some method invocations.

This is the proper fix for 72b7bc0a284cc.

* Enhanced iasl(8) output for Switch/Case statements.

Sync ACPICA with Intel's version 20160729.

* Restructured and standardized the C library configuration for
ACPICA.

* AML interpreter: Allows for execution of so-called "executable"
AML code outside of control methods, not just at the module level
(top level) but also within any scope declared outside of a
control method - Scope{}, Device{}, Processor{}, PowerResource{},
and ThermalZone{}. Lv Zheng.

* iASL: Add full support for the RASF ACPI table (RAS Features Table).

* iASL: Allows for compilation/disassembly of so-called "executable"
AML code (see above).

kernel: Sync ACPICA with Intel's version 20140325.

As far as I can see, the most important change is a fix for the auto-
serialization of control methods so that the currently executing AML
SyncLevel is ignored when invoking such a method. This fixes an issue
seen in some systems showing AE_AML_MUTEX exceptions since 20140214
which had to set hw.acpi.auto_serialize_methods to 0 to work around
the issue.

This was actually reported for DragonFly by Andrey Oktyabrskiy (see
http://lists.dragonflybsd.org/pipermail/users/2014-February/109376.html).

See sys/contrib/dev/acpica/changes.txt for a complete list of all

sys/acpi: Bring in Intel's acpica-unix2-20131218 verbatim.

On acpica.org, -unix is the version with an Intel license and
-unix2 is the BSD/GPL dual licensed version. I didn't want to
call the directory acpica-unix2 instead of our acpica-unix so
I settled on simply acpica.

Further updates would be done in-place in that directory.
