ACPICA: Cleanup memory allocation macros and configurability.
In the common case, the ACPI_ALLOCATE and related macros now resolve
directly to their respective acpi_os* OSL interfaces. Two options:
1) The ACPI_ALLOCATE_ZEROED macro defaults to a simple local implementation
by default, unless overridden by the USE_NATIVE_ALLOCATE_ZEROED define.
2) For ACPI execution simulation environment (AcpiExec) which is not
shipped with the Linux kernel, the macros can optionally be resolved to
the local interfaces that track each allocation (used to immediately
detect memory leaks).
