Sync ACPICA with Intel's version 20170303.

Nothing big, really:

* The licensing information at the start of each source code module has
been updated. In addition to the Intel license, the dual GPLv2/BSD
license has been added for completeness. Now, a single version of the
source code should be suitable for all ACPICA customers. This is the
major change for this release since it affects all source code modules.

* Fixed two issues with the common asltypes.h header that could cause
problems in some environments (Kim Jung-uk).

* Disassembler: fixed a regression introduced in 20170224. A fix for a
memory leak related to resource descriptor tags (names) could fault
when the disassembler was generated with 64-bit compilers.

Sync ACPICA with Intel's version 20160108.

This includes the 20151218 upgrade which we had to revert again because
of a bug found by tkusumi. The only major change in 20160108 is a fix
for this bug.

20151218 changes:

* Execute "module-level code" as ACPI tables are loaded into the
namespace during initialization and install the default operation
region handlers for the SystemMemory, SystemIO and PCI_Config
address spaces before any ACPI tables are loaded (in order to
enable module-level code to access these address spaces). Also,
several changes to the internal _REG support and to utilities
in conjunction with these changes.

20160108 changes:

* Fixed a regression introduced in version 20151218 concerning the
execution of so-called module-level ASL/AML code. Namespace objects
created under a module-level If() construct were not properly/fully
entered into the namespace and could cause an interpreter fault when
accessed.

* Fixed a problem with the compilation of the GpioIo and GpioInt resource
descriptors. The _PIN field name was incorrectly defined to be an array
of 32-bit values, but the _PIN values are in fact 16 bits each. This
would cause incorrect bit width warnings when using Word (16-bit) fields
to access the descriptors.

Additionally, some minor fixes, features etc. were added.
