[ros-arm-bringup] 34091: - Fix several interlocked list functions -- they should return NULL if the list is empty. - Fix a bug in FreeLDR-ARM, we forgot to set the RegistryLength, resulting in a corrupted registry. We can now load the system registry. - Enable code to handle DPC, Timer and Deferred Ready cleanup (portable code that's already written). - Enable code to handle quantum end. - We now load all the way to IoInitSystem!IopInitializeBootDrivers.
