	(libnss_db-routines): Likewise.
	* nss/key-lookup.c: New file.

	* nss/getXXent_r.c (last_nip): Remember last service used since
	last setXXent call.
	(SETFUNC): Don't force to work through whole list of services in
	call to __nss_next.
	Update last_nip if necessary.
	(ENDFUNC): Only process endXXent function up to currently used
	last service.
	(GETFUNC): Update last_nip if necessary.

	* nss/nss_files/files-netgrp.c (_nss_netgroup_parseline): Don't
	make static.

	* rpc/auth_des.h: New file.
	* sunrpc/Makefile (headers): Add auth_des.h.
	(routines): Add publickey.
	* sunrpc/publickey.c: New file.  Interface to public key handling.
