    Implemented support for "wake" GPEs via interaction between
    GPEs and the _PRW methods.  Every GPE that is pointed to by
    one or more _PRWs is identified as a WAKE GPE and by default
    will no longer be enabled at runtime.  Previously, we were
    blindly enabling all GPEs with a corresponding _Lxx or _Exx
    method - but most of these turn out to be WAKE GPEs anyway.
    We believe this has been the cause of thousands of
    "spurious" GPEs on some systems.
    
    This new GPE behavior is can be reverted to the original
    behavior (enable ALL GPEs at runtime) via a runtime flag.
    
    Fixed a problem where aliased control methods could not
    access objects properly.  The proper scope within the
    namespace was not initialized (transferred to the target of
    the aliased method) before executing the target method.
    
    Fixed a potential race condition on internal object
    deletion on the return object in AcpiEvaluateObject. 
    
    Integrated a fix for resource descriptors where both
    _MEM and _MTP were being extracted instead of just _MEM.
    (i.e. bitmask was incorrectly too wide, 0x0F instead of 0x03.)
    
    Added a special case for ACPI_ROOT_OBJECT in AcpiUtGetNodeName,
    preventing a fault in some cases.
    
    Updated Notify() values for debug statements in evmisc.c
    
    Return proper status from AcpiUtMutexInitialize,
    not just simply AE_OK.
