    Completed a major overhaul of the Resource Manager code -
    specifically, optimizations in the area of the AML/internal
    resource conversion code. The code has been optimized to
    simplify and eliminate duplicated code, CPU stack use has
    been decreased by optimizing function parameters and local
    variables, and naming conventions across the manager have
    been standardized for clarity and ease of maintenance (this
    includes function, parameter, variable, and struct/typedef
    names.)
    
    All Resource Manager dispatch and information tables have
    been moved to a single location for clarity and ease of
    maintenance. One new file was created, named "rsinfo.c".
    
    The ACPI return macros (return_ACPI_STATUS, etc.) have
    been modified to guarantee that the argument is
    not evaluated twice, making them less prone to macro
    side-effects. However, since there exists the possibility
    of additional stack use if a particular compiler cannot
    optimize them (such as in the debug generation case),
    the original macros are optionally available.  Note that
    some invocations of the return_VALUE macro may now cause
    size mismatch warnings; the return_UINT8 and return_UINT32
    macros are provided to eliminate these. (From Randy Dunlap)
    
    Implemented a new mechanism to enable debug tracing for
    individual control methods. A new external interface,
    acpi_debug_trace(), is provided to enable this mechanism. The
    intent is to allow the host OS to easily enable and disable
    tracing for problematic control methods. This interface
    can be easily exposed to a user or debugger interface if
    desired. See the file psxface.c for details.
    
    acpi_ut_callocate() will now return a valid pointer if a
    length of zero is specified - a length of one is used
    and a warning is issued. This matches the behavior of
    acpi_ut_allocate().
