[PATCH] extras multipath update

 incremental to 20031220,

 2003-12-22 multipath-010
        * don't print .sg_dev if equal to .dev (2.6) in print_path()
        * since the kernel code handles defective paths, remove all
          code to cope with them :
                * move do_tur() to unused.c
                * remove .state from path struct
                * remove .state settings & conditionals
        * add a cmdline switch to force maps to failover mode,
          ie 1 path per priority group
        * add default policies to the whitelist array (spread io ==
          MULTIBUS / io forced to 1 path == FAILOVER)
        * move get_disk_size() call out of add_map() to coalesce()
        * comment tricky coalesce() fn
        * bogus unsused.c file renamed to unused.c
