This patchset tries to add usb-scsi model for SCSI controller.

"usb-uas is a pure UAS (usb attached scsi) emulation.
The emulation works like any other scsi hba emulation (eps, lsi, virtio,
megasas, ...).  It provides just the HBA where you can attach scsi
devices as you like using '-device'.  A single scsi target with up to
256 luns is supported. For now only usb 2.0 transport is supported."

libvirt XML snip
  <devices>
    <controller type='usb' index='2' model='ehci'>
    </controller>
    <controller type='scsi' index='0' model='usb-scsi'>
Same objection as with the usb-net series - we need a more explicit
name here.

      I choose usb-scsi because of virtio-scsi,
      idVendor is QEMU.
      idProduct is "USB Attached SCSI HBA".
      I originally named it usb-uas. Is it okay?
      To be honest, it is hard to think of a better name.
      Any better name is welcome. :)
