Update.

1998-10-18  Ulrich Drepper  <drepper@cygnus.com>

	* resolv/nss_dns/dns-host.c: Add missing errnop parameter to the
	NSS functions.
	* resolv/nss_dns/dns-network.c: Likewise.

	* grp/Makefile: Don't search for linuxhtreads in add-ons, use
	have-thread-library to determine whether threads are available.
	* pwd/Makefile: Remove wrong comment.

	* inet/Makefile: Define CFLAGS-gethstbyad_r.c, CFLAGS-gethstbynm_r.c,
	and CFLAGS-gethstbynm2_r.c to -DUSE_NSCD=1.

	* locale/C-messages.c: Define default strings for YESTR and NOSTR.

	* nss/Versions: Add __nss_hosts_lookup.

	* nss/getXXbyYY.c: Remove unneeded assignment.

	* nss/getXXbyYY_r.c: Include nscd/nscd_proto.h only if needed.

	Almost complete rewrite of the NSCD to make it smaller, faster,
	add more functionnality and make it easier to extend.
	* nscd/Makfile (routines): Add nscd_gethst_r.
	(nscd-modules): Add hstcache, gethstbyad_r, gethstbynm2_r, and cache.
	* nscd/cache.c: New file.
	* nscd/gethstbyad_r.c: New file.
	* nscd/gethstbynm2_r.c: New file.
	* nscd/hstcache.c: New file.
	* nscd/nscd_gethst_r.c: New file.
	* nscd/connections.c: Rewritten.  Don't start new thread for every
	new connection.  Use a fixed set of threads which handle all
	connections and also the cache cleanup.
	* nscd/grpcache.c: Rewritten to use generic cache handling functions
	in cache.c.
	* nscd/nscd.c: Recognize new parameter nthreads.  Adjust initialization
	for rewrite.  Remove handle_requests function.
	* nscd/nscd.h (NSCD_VERSION): Bump to 2.
	Define new data structure for the new unified cache and the host
	database entries.
	* nscd/nscd_conf.c: Rewrite parsing partly to allow adding of more
	databases easily.  Recognize check-files and threads definitions.
	* nscd/nscd.conf: Add definition of enable-cache and check-files to
	passwd and group definitions.  Add new set of definitions for hosts.
	* nscd/nscd_getgr_r.c: Rewrite for new protocol.
	* nscd/nscd_getpw_r.c: Likewise.
	* nscd/nscd_proto.h: Add prototype for host database functions.
	* nscd/nscd_stat.c: Rewrite to simplify printing of information
	for many databases.
	* nscd/dbg_log.c: Remove unnecessary variable initializations.
	Global variable debug_flag is renamed to dbg_level.
	* nscd/dbg_log.h: Declare set_logfile.
