[PATCH] extras multipath update

An important one, against stock udev-009 :

 2003-12-20 multipath-010
        * big ChangeLog update
        * start to give a little control over target params :
          introduce cmdline arg -i to control polling interval
        * cope with hotplug-style calling convention :
          ie "multipath scsi $DEVPATH" ... to avoid messing with
          online maps not concerned by an event
        * example hotplug agent to drop in /etc/hotplug.d/scsi
        * revert the run & resched patch : unless someone proves me
          wrong, this was overdesigned
        * move commented out functions in unused.c
        * update multipath target params to "udm[23] style"
        * mp target now supports nr_path == 1, so do we
        * add gratuitous free()
        * push version forward
