            This program demo how INIT_LIST works in EFI system. 
            By using typedef (FUNC_POINTER)(fun_arg1,fun_arg2,...) 

            We can write make as 
            BootOptionDpMatchingFunctions = \
                LocateDevicePathTest,\
                PartitionDevicePathTest,\
                UsbClassDevicePathTest,\
                BbsDevicePathTest,\
                AmiBbsDevicePathTest,\
                AmiDeviceNameDevicePathTest,\
                DeviceTypeDevicePathTest,

            And there'll be \D arg in make file for C using, ex:
            INIT_LIST_DEFINES=/D"INIT_LIST=$(INIT_LIST)"

            Thus, the term "EndOfInitList" becomes dummy value,
            it will always be defined to NULL :
            INIT_FUNCTION* InitList[] = {INIT_LIST NULL};
