* nis/nis_call.c (__prepare_niscall): New function. Split out cvs/fedora-glibc-20060521T2153

	from __do_niscall.
	* nis/nis_table.c (__create_ib_request): Renamed from create_ib_request
	and exported.
	(__follow_path): New function.  Split out from nis_list.
	* nis/nis_xdr.h: Add libnsl_hidden_proto for _xdr_ib_request and
	_xdr_nis_result.
	* nis/nis_xdr.c: Add libnsl_hidden_def for _xdr_ib_request and
	_xdr_nis_result.
	* nis/libnsl.h: Declare __prepare_niscall, __create_ib_request,
	and __follow_path.
	* nis/Versions: Export __prepare_niscall, __create_ib_request,
	__follow_path, __do_niscall3, _xdr_ib_request, and _xdr_nis_result
	from libnsl for version GLIBC_PRIVATE.
	* nis/nisplus-parser.h: Remove _nss_nisplus_parse_pwent_chk.
	Remove entry parameter from _nss_nisplus_parse_pwent and
	_nss_nisplus_parse_grent.
	* nis/nss_nisplus/nisplus-parser.c: Likewise.
	* nis/nss_nisplus/nisplus-pwd.c: Remove support for SETENT_BATCH_READ
	again.  Rewrite getpwent handling to not use nis_first_entry and
	nis_next_entry.  Roll out own niscall handling.
	* nis/nss_nisplus/nisplus-grp.c: Likewise.

	* sunrpc/xdr_rec.c: Fix typo in comment.
