Implemented _CID support for PCI Root Bridge detection. If the _HID
does not match the predefined root bridge IDs, the _CID list (if present)
is now obtained and also checked for an ID match

Fixed a problem with a possible race condition between threads executing
AcpiWalkNamespace and the AML interpreter. This condition was removed by
modifying AcpiWalkNamespace to (by default) ignore all temporary
namespace entries created during any concurrent control method execution

Completed an AML interpreter performance enhancement for control method
execution. Previously a 2-pass parse/execution, control methods are now
completely parsed and executed in single pass. This improves overall
interpreter performance by ~25%, reduces code size, and reduces CPU stack use.

Remove flags parameter for acpi_{get,set}_register().
It is no longer necessary now that these functions use a
spinlock for mutual exclusion.

Fixed a regression where an error was no
longer emitted if a control method attempts to create 2
objects of the same name. This previously and now returns
AE_ALREADY_EXISTS. When this exception occurs, it invokes
the mechanism that will dynamically serialize the control
method to possible prevent future errors. (BZ 440)
