	* hurd/hurdlookup.c (__hurd_file_name_lookup_retry,
	__hurd_file_name_lookup, __hurd_file_name_split): Add & use LOOKUP argument. 
	Rename nested function lookup to lookup_op.
	(__file_name_lookup, __file_name_lookup_under):
	Pass 0 for lookup arg to __hurd_file_name_lookup.
	(__file_name_split): Likewise for __hurd_file_name_split.
	* hurd/path-lookup.c (hurd_file_name_path_lookup): Add LOOKUP argument.
	Rename nested function lookup to scan_lookup.
	(file_name_path_lookup): Pass 0 for lookup arg to
	hurd_file_name_path_lookup.
	* hurd/hurd/lookup.h (__hurd_file_name_lookup, hurd_file_name_lookup,
	__hurd_file_name_lookup_retry, hurd_file_name_lookup_retry: 
	__hurd_file_name_split, hurd_file_name_split, hurd_file_name_lookup):
	Add LOOKUP argument.
	* sysdeps/mach/hurd/access.c (__access): Pass 0 lookup arg to
	__hurd_file_name_lookup.

+   LOOKUP is a function to do the actual filesystem lookup.  It is passed the
+   same arguments that the dir_lookup rpc accepts, and if 0, __dir_lookup is
+   used.

    The second callback function GET_DTABLE_PORT should behave like `getdport'.
 
    All these functions return zero on success or an error code on failure.  */
