These utilities are for types generated from AIDL. Since the types end up in the 'aidl' namespace (NDK backend), it makes sense to keep the utilities in the same namespace. While changing the namespace, I've found numerous useless includes of 'Utils.h' and removing them, also reorganizing lists of includes along the way to match the style guide.
