The function, efi_init_obj_list(), can be shared in different pseudo efi applications, like bootefi/bootmgr as well as my efishell. Moreover, it will be utilized to extend efi initialization, for example, my "removable disk support" patch and "capsule-on-disk support" patch in the future. So with this patch, it will be moved to a new file, efi_setup.c, under lib/efi_loader and exported, making no changes in functionality.
