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
