	Make /hurd/magic support translator delegation via /servers/magic.
	* magic.c (struct magic): New structure.
	(magic, directory, dirbuf, dirbufsize): Variables removed,
	not members of struct magic.
	(trivfs_modify_stat, magic_getroot, trivfs_S_dir_readdir): Use a
	struct magic hanging off CNTL->hook rather than global variables.
	(trivfs_append_args): Likewise.
	(trivfs_S_dir_lookup): Likewise.  Let magic string be null to indicate
	prepending nothing in --directory mode.
	(parse_opt): Use struct magic in STATE->input instead of globals.
	If no argument, turn on --directory and leave M->magic null.
	(argp): New static variable, instead of auto in main.
	(main): Set both trivfs hook functions unconditionally.
	Use a struct magic, pass it to argp_parse and store it in FSYS->hook.
	Move directory buffer setup to ...
	(parse_opt): ... here, do it on ARGP_KEY_SUCCESS.
	(magic_open): Track users with a count.
	(magic_protid_destroy): New function to track users.
	(main): Set trivfs_protid_destroy_hook to that.
	(trivfs_goaway): Call ports_destroy_right if FSYS has no users.
	(all_fsys): New variable, list of all filesystems.
	(trivfs_clean_cntl): New function, exit if no filesystems left.
	(main): Put FSYS on that list.  On timeout with no RPCs, try
	trivfs_goaway on each filesystem on the list.
	(trivfs_S_fsys_forward): New function.
	(delegate): New variable.
	(options): New option -U/--use-server to set it.
