* move enc/dec definitions to NR_NAS_defs.h and add new lib file nr_fgs_nas_lib.c both used by nr_nas_msg.c * move utility macros to fgs_nas_utils.h: this can be used in all the 5GMM, 5GSM lib files * use nr_nas_msg.c for handlers/callbacks only, it should call the enc/dec functions in nr_fgs_nas_lib and in the 5GMM, 5GSM libs * 5GMM, 5GSM libs should only do the enc/dec of the NAS message contents
