There are a bunch of protocols which should be exposed by GUID but are not. Add a helper macro to create an efi_object, to avoid much typing.
Note that using the pointer for efiobj->handle is semi-arbitrary. We just need a unique value to match the efiobj supporting the protocol with the handle that LocateHandle() returns..
See LibLocateProtocol() in gnu-efi. It does LocateHandle() to find all the handles, and then loops over them calling HandleProtocol() with the GUID of the protocol it is trying to find.
