scsi: device version property
This patch adds a new property named 'ver' to scsi-disk which allows to
specify the version which the virtual disk/cdrom should report to the
guest. By default this is the qemu version (i.e. 0.12). usage:
-drive if=none,id=disk,file=...
-device lsi
-device scsi-disk,drive=disk,bus=scsi.0,unit=0,ver=42
You can also switch the version for all scsi drives using:
-global scsi-disk.ver=42
