    Implemented the use of a cache object for all internal
    namespace nodes. Since there are about 1000 static nodes
    in a typical system, this will decrease memory use for
    cache implementations that minimize per-allocation overhead
    (such as a slab allocator.)
    Removed the reference count mechanism for internal
    namespace nodes, since it was deemed unnecessary. This
    reduces the size of each namespace node by about 5%-10%
    on all platforms. Nodes are now 20 bytes for the 32-bit
    case, and 32 bytes for the 64-bit case.
    Optimized several internal data structures to reduce
    object size on 64-bit platforms by packing data within
    the 64-bit alignment. This includes the frequently used
    ACPI_OPERAND_OBJECT, of which there can be ~1000 static
    instances corresponding to the namespace objects.
    Added two new strings for the predefined _OSI method:
    "Windows 2001.1 SP1" and "Windows 2006".
    Split the allocation tracking mechanism out to a separate
    file, from utalloc.c to uttrack.c. This mechanism appears
    to be only useful for application-level code. Kernels may
    wish to not include uttrack.c in distributions.
    Removed all remnants of the obsolete ACPI_REPORT_* macros
    and the associated code. (These macros have been replaced
    by the ACPI_ERROR and ACPI_WARNING macros.)
