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.

enables control method invocations as Target operands to

some method invocations.

This is the proper fix for 72b7bc0a284cc.

* Temporarily reverted the new arbitrary bit length/alignment support
in AcpiHwRead/AcpiHwWrite for the Generic Address Structure. There
have been a number of regressions with the new code that need to be
fully resolved and tested before this support can be finally
integrated into ACPICA. Apologies for any inconveniences these
issues may have caused.

* The ACPI message macros are not configurable (ACPI_MSG_ERROR,
ACPI_MSG_EXCEPTION, ACPI_MSG_WARNING, ACPI_MSG_INFO,
ACPI_MSG_BIOS_ERROR, and ACPI_MSG_BIOS_WARNING). Lv Zheng.

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.
