ACPICA: Update global variable definitions. No functional change.
Move all of the public globals to acpixf.h for the convenience of users. Also: Adds #ifndef/#endif conditions arround ACPI_GLOBAL and ACPI_INIT_GLOBAL definition so that OSPMs might be able to: 1. Redefine ACPI_GLOBAL/ACPI_INIT_GLOBAL into no-op, and 2. Redefine external global variables into immediates to implement stubs for them. Lv Zheng.
