* nis/nss_nis/nis-netgrp.c: Remove locking by using data in struct __netgrent object passed in instead of global variables. Optimize. * nis/nss_nisplus/nisplus-netgrp.c: Remove locking by using data in struct __netgrent object passed in instead of global variables. * inet/netgroup.h (struct __netgrent): Add service_user field. Move cursor in anonymous union, add new field location to that union. * inet/getnetgrent_r.c: Extensive rewrite to really enable concurrent uset of set/get/endnetgrent and innetgr.
