scsi-disk: add scsi-block for device passthrough
scsi-block is a new device that supports device passthrough of Linux block devices (i.e. /dev/sda, not /dev/sg0). It uses SG_IO for commands other than I/O commands, and regular AIO read/writes for I/O commands. Besides being simpler to configure (no mapping required to scsi-generic device names), this removes the need for a large bounce buffer and, in the future, will get scatter/gather support for free from scsi-disk.
