Blktool is a multi-purpose tool to manage common block concepts

Blktool is a multi-purpose tool that aims to a common place to management common block concepts, across a wide variety of hardware. For example, rather than having to learn and use different tools for ATA or SCSI or I2O for the concept of "suspend", in the future one will simply do "blktool /dev/foo suspend" and it will work, regardless of what type of device it is.
