URL:    http://git.debian.org/?p=pkg-mdadm/mdadm.git;a=commit;h=7efa6bc34ff0357a491e64495a9b3a7483971000

Update udev rules for hotplug support.

- split the rules for handling components of array to be clearly
  separate from rules for handling the arrays themselves.
- add call to "-If" when removing a device
- uncomment the --incremental call when adding a device.
