Paolo Bonzini f651526271 scsi: refine constants for READ CAPACITY 16
Rename SERVICE_ACTION_IN to SERVICE_ACTION_IN_16 to distinguish
from the 12-byte CDB variant, and add a constant for the subcommand.

Paolo Bonzini 6dc06f08b3 scsi: add support for unit attention conditions
Unit attention conditions override any sense data the device already
has.  Their signaling and clearing is handled entirely by the SCSIBus
code, and they are completely transparent to the SCSIDevices.

SET_WINDOW command is vendor-specific only.
So we shouldn't try to emulate it.

Christoph Hellwig ea3bd56f56 scsi-disk: support WRITE SAME (16) with unmap bit
Support discards via the WRITE SAME command with the unmap bit set, and
tell the initiator about the support for it via the block limit and the
new thin provisioning EVPD pages.  Also fix the comment which incorrectly
describedthe block limits EVPD page.

Hannes Reinecke f017132793 scsi: Return SAM status codes
Traditionally, the linux stack is using SCSI status codes
which are shifted by one as compared to those defined in SAM.
A SCSI emulation should naturally return the SAM defined codes,
not the linux ones.
So to avoid any confusion this patch modifies the existing
definitions to match those found in SAM and removes any
(now obsolete) byte-shift from the returned status codes.

Nicholas Bellinger c7126d5b32 scsi-bus: Add MAINTENANCE_IN and MAINTENANCE_OUT SCSIRequest xfer and mode assignments
This patch updates hw/scsi-bus.c to add MAINTENANCE_IN and MAINTENANCE_OUT case in
scsi_req_length() for TYPE_ROM with MMC commands.  It also adds the MAINTENANCE_OUT
case in scsi_req_xfer_mode() to set SCSI_XFER_TO_DEV for outgoing write data.
