Update.

	* nscd/cache.c (cache_search): Keep track of how many chain links
	we searched and update table statistics.
	(cache_add): Keep track of how many values are in the table.
	(prune_cache): Likewise.  Keep track of locking success.
	Print messages about removed entries in separate pass.
	* nscd/connections.c (handle_request): Don't print debug message here.
	The caller will do it.  Keep track of locking success.
	(nscd_run): Print debug message.  Also print PID of the client process.
	* nscd/nscd.c (start_time): New variable.
	(main): Remember start time.
	* nscd/nscd.h: Declare start_time.
	(struct database): Add more members for new statistics.
	* nscd/nscd_stat.c: Add support for sending, receiving, and printing
	of new statistics.
