Update.

* nis/nss_nis/nis-hosts.c: Make _nss_nis_endhostent an alias of
	_nss_nis_sethostent.  Work around the different prototypes.
	* nis/nss_nis/nis-grp.c: Make _nss_nis_endgrent an alias of
	_nss_nis_setgrent.  Work around the different prototypes.
	* nis/nss_nis/nis-ethers.c (internal_nis_endetherent): New
	function.  Split out from _nss_nis_endetherent.
	(internal_nis_setetherent): Use internal_nis_endetherent instead of
	duplicating the code.
	* nis/nss_nis/nis-alias.c: Make _nss_nss_nis_endaliasent an alias
	of _nss_nis_setaliasent.
	* nis/nss_nis/nis-service.c (internal_nis_setservent): Reuse
	internal_nis_endservent code, don't duplicate it.
