[Qemu-devel] SCSI fixes

I added some new  SCSI commands, which are used by Linux.

I found the reason for boot problems, where disk size was zero. Linux ESP 
driver uses (very rarely) the ESP command Set ATN and Stop, which is in fact 
not similar to Set ATN command. The way of sending the command seems to be 
very different. I'm still looking for a solution.

Hmm, this sounds like a partially a Linux bug. The qemu devices only report 
SCSI-3 rev 1, which doesn't define some of these commands.
However implementing them seems harmless so I've fixed a couple of bugs and 
applied the patch.

If I remember correctly, Linux uses the commands even if the device claims 
conformance to SCSI-1 (like it was before the SCSI reorg).

Thanks!
