Mike: In original thread, I don't receive the objection to change the library INF file name. So, I merge original patch.
Now, the downstream break is found. If you think DevicePathUtilitiesStandaloneMm is required, I would suggest to add it for long term to keep the compatibility. Yanbo: You only need to add new DevicePathUtilitiesStandaloneMm.inf. Its content is same to UefiDevicePathLibBase.inf.
