* nis/nss_nisplus/nisplus-pwd.c (_nss_pwd_create_tablename):
Renamed from _nss_create_tablename. Export from file (but not DSO). (pwd_tablename_val): Renamed from tablename_val, mark hidden. (pwd_tablename_len): Renamed from tablename_len, mark hidden. Change all users. * nis/nss_nisplus/nisplus-spwd.c (_nss_create_tablename): Removed. Use _nss_pwd_create_tablename now. Use pwd_tablename_val and pwd_tablename_len. Remove unnecessary variables, general cleanup. * nis/nss_nisplus/nisplus-grp.c: Likewise.
