* nis/nis_call.c (__prepare_niscall): New function. Split outcvs/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. 2006-05-18 David Woodhouse <dwmw2@redhat.com>
