	* inet/Makefile (routines): Add getipnodebynm.
	* inet/getipnodebynm.c: New file.
	* nss/digits_dots.c: If HAVE_TYPE is define type contains the
	interface type.
	* nss/nss_files/files-XXX.c: Define EXTRA_ARGS, EXTRA_ARGS_DECL, and
	EXTRA_ARGS_VALUE is not already done.
	(internal_getent): Allow extra parameters and pass them to parse_line.
	(_nss_files_get,ENTNAME_r): Pass extra parameters to internal_getent.
	(_nss_files_get##name##_r): Likewise.
	* nss/nss_files/files-hosts.c: Define EXTRA_ARGS, EXTRA_ARGS_DECL,
	and EXTRA_ARGS_VALUE to pass flags and type to parser.
	Add getipnodebyname function.
	* nss/nss_files/files-parse.c: Define EXTRA_ARGS, EXTRA_ARGS_DECL, and
	EXTRA_ARGS_VALUE is not already done.
	(parse_line): Add EXTRA_ARGS_DECL to parameter list.
	* nss/nss_db/db-XXX.c (lookup): Allow extra parameters and pass them
	to parse_line.
	(_nss_db_get##name##_r): Pass extra parameters to lookup.
	(_nss_db_get,ENTNAME_r): Likewise.
	* sysdeps/generic/if_index.c (__protocol_available): New function.
	* sysdeps/unix/sysv/linux/if_index.c: Likewise.
