* nss/nss_files/files-parse.c (parse_list): Count null in EOL calc.

	Move DB code into separate -ldb library.
	* db/Makefile (extra-libs): New variable, list libdb.
	(routines): Renamed to libdb-routines.
	* shlib-versions: Add libdb=2.

	* nss/network-lookup.c (DEFAULT_CONFIG): New macro.
	* nss/host-lookup.c (DEFAULT_CONFIG): New macro.

	* nss/nsswitch.c (nss_parse_service_list): Use __strncasecmp instead
	of strncasecmp.  Extend syntax to grok [!foo=bar].

	* sysdeps/generic/strncase.c: Define __strncasecmp with strncasecmp as
	weak alias.
	* string/string.h: Declare __strncasecmp.

	* nss/nsswitch.c (nss_parse_file): Call __getline, not getline.
	(service_alias): Variable removed.
	(nss_parse_service_list): New function, broken out of nss_getline.
	Remove alias conversion; we will just use symlinks.
	(__nss_database_lookup): Take new string arg DEFCONFIG.
	If no entry exists, make one with service list parsed from that.
	* nss/nsswitch.h: Update protocol for __nss_database_lookup.
	* nss/XXX-lookup.c (DEFAULT_CONFIG): New macro, set to 0 if undefined.
	(DB_LOOKUP_FCT): Pass it to _nss_database_lookup.

	* grp/initgroups.c: Rewritten using getgrent.  Handle unlimited group
	list size.

	* sunrpc/xdr.c (xdr_int): #if 0 out unresolved references in dead code.

	* locale/programs/locale.c (long_options): Short form of
	--version option is `-V'.
	(main): Recognize `-V' as option, not `-v'.
	Call `usage' instead of printing error message for illegal
	option.
	(usage): Document `-V'.
