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.

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.

request parsing helper functions.
Use them in scsi-disk.c too.

Largely based on <scsi/scsi.h> from linux. Added into the tree so we
can use the defines everywhere, not just in scsi-generic.c (which is
linux-specific).
