[PATCH] extras multipath update

 incremental to 20031222-2,

 2003-12-22 multipath-010
        * tweak the install target in Makefile
        * stop passing fds as argument : this change enable a strict
          segregation of ugly 2.4 code
        * sysfs version of get_lun_strings()
        * be careful about the return of get_unique_id() since errors
          formerly caught up by if(open()) in the caller fn are now returned
          by get_unique_id()
        * send get_serial() in unused.c
