qdev/scsi: add scsi bus support to qdev, convert drivers.

* Add SCSIBus.
 * Add SCSIDeviceInfo, move device callbacks here.
 * add qdev/scsi helper functions.
 * convert drivers.

Adding scsi disks via -device works now, i.e. you can do:

 -drive id=sda,if=none,...
 -device lsi
 -device scsi-disk,drive=sda

legacy command lines (-drive if=scsi,...) continue to work.
