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.
