This series is mostly a refresh of Hannes's patches at
https://patchew.org/QEMU/20201116184041.60465-1-h...@suse.de/, which
haven't been applied yet because they broke the testsuite.
In addition to Hannes's introduction of host status in the SCSI
subsystem, which survives mostly in patches 3 and 6-10, I am also changing
scsi_handle_rw_error to always pass down guest-recoverable sense codes,
even if rerror=stop/werror=stop. Without this change, [rw]error=stop are
mostly unusable because the guest will stop even for unit attention sense.
