scsi: add support for ATA_PASSTHROUGH_xx scsi command
Correct the command names of opcode 0x85 and 0xa1, and calculatetheir xfer size from CDB.

scsi: Fix LOAD_UNLOAD
Change operation code of LOAD_UNLOAD command to 0x1b as described insection 7.3 of the SCSI Stream Commands spec.

scsi: Add basic support for SCSI media changer commands.
This adds basic support for SCSI media changer commands.Not all commands are supported as of now, but enough to coverbasic functionality.

scsi: Fix transfer length for READ POSITION commands.
The transfer length depends on the specific service actioncode, as defined in the SCSI stream commands spec section 7.7.Up to now only the extended form was supported.
scsi-disk: implement READ DISC INFORMATION
This command is not necessary for CD-ROM and DVD-ROM, but some versions ofudev trip on its absence.

scsi: parse 16-byte tape CDBs
The transfer length for these commands is different from the transferlength of the corresponding disk commands, so parse it specially.
scsi: add SANITIZE command
scsi: update list of commands
Add more commands and their names, and remove SEEK which is obsolete.Instead, use SET_CAPACITY which is still in SSC.

atapi/scsi: unify definitions for MMC
The definitions in ide/internal.h are duplicates, since ATAPI commandsactually come from SCSI. Use the ones in scsi-defs.h and move themissing ones there. Two exceptions:
- MODE_PAGE_WRITE_PARMS conflicts with the "flexible disk geometry"...
atapi: move GESN definitions to scsi-defs.h
As a complement to the previous patch, move definitions for GET EVENTSTATUS NOTIFICATION from the two functions to scsi-defs.h.
The NCR_* constants are just bit values corresponding to the ENC_*values, with no offsets even, so keep just one copy....
scsi-disk: add stubs for more MMC commands
This patch adds a few stub implementations for MMC commands toscsi-disk, to be filled in later in the series. It also adds toscsi-defs.h constants for commands implemented by ide/atapi.c,when missing.

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

scsi: add support for unit attention conditions
Unit attention conditions override any sense data the device alreadyhas. Their signaling and clearing is handled entirely by the SCSIBuscode, and they are completely transparent to the SCSIDevices.
scsi: move handling of REPORT LUNS and invalid LUNs to common code

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

scsi: Remove REZERO_UNIT emulation
REZERO_UNIT command is obsolete. Remove support for it.
scsi: Sanitize command definitions
Sanitize SCSI command definitions.Add _10 suffix to READ_CAPACITY, WRITE_VERIFY, VERIFY, READ_LONG,WRITE_LONG, and WRITE_SAME.Add new command definitions for LOCATE_10, UNMAP, VARLENGTH_CDB,WRITE_FILEMARKS_16, EXTENDED_COPY, ATA_PASSTHROUGH, ACCESS_CONTROL_IN,...
scsi-disk: Remove 'drive_kind'
Instead of using its own definitions scsi-disk shouldbe using the device type of the parent device.
scsi-disk: support WRITE SAME (16) with unmap bit
Support discards via the WRITE SAME command with the unmap bit set, andtell the initiator about the support for it via the block limit and thenew thin provisioning EVPD pages. Also fix the comment which incorrectly...
scsi: Return SAM status codes
Traditionally, the linux stack is using SCSI status codeswhich 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...
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 inscsi_req_length() for TYPE_ROM with MMC commands. It also adds the MAINTENANCE_OUTcase in scsi_req_xfer_mode() to set SCSI_XFER_TO_DEV for outgoing write data....

scsi: add read/write 16 commands.
Add READ_16 + friends to scsi-defs.h, scsi_command_name() and therequest parsing helper functions.
Use them in scsi-disk.c too.
scsi: add scsi-defs.h
Largely based on <scsi/scsi.h> from linux. Added into the tree so wecan use the defines everywhere, not just in scsi-generic.c (which islinux-specific).
