	* nss/nsswitch.c (nss_parse_file): Call __getline, not getline.
	(service_alias): Variable removed.
	(nss_parse_service_list): New function, broken out of nss_getline.
	Remove alias conversion; we will just use symlinks.
	(__nss_database_lookup): Take new string arg DEFCONFIG.
	If no entry exists, make one with service list parsed from that.
	* nss/nsswitch.h: Update protocol for __nss_database_lookup.
	* nss/XXX-lookup.c (DEFAULT_CONFIG): New macro, set to 0 if undefined.
	(DB_LOOKUP_FCT): Pass it to _nss_database_lookup.
