(parse_opt):
New function (was nested in main). (doc): Make an initialized array. (fsys_port_class, root_port_class, port_bucket, trivfs_protid_portclasses, trivfs_protid_nportclasses, trivfs_cntl_portclasses, trivfs_cntl_nportclasses): Variables removed. (argp, argp_kids): New variables (were nested in main). (main): Don't set or use port class/bucket variables, let trivfs_startup do it. Add FSYS variable. (trivfs_goaway): Get ROOT_PORT_CLASS from FSYS.
