Subject: [PATCH]udev:Extend udev to support move events

As of now, udev does not support move events that are generated when
network interfaces are renamed. This patch extends udev to support move
events. With this patch udev would support rules like 

ACTION=="move", SUBSYSTEM=="net", PROGRAM="netif_id %k"
