Merge remote-tracking branch 'remotes/bonzini/tags/for-upstream' into staging

SCSI patches include bug fixes from Fam and Peter, improved error
reporting from Fam and a fix for DPRINTF bitrot.  Memory patches try
again to initialize name from the QOM name.

# gpg: Signature made Thu 28 Aug 2014 15:10:31 BST using RSA key ID 9B4D86F2
# gpg: Good signature from "Paolo Bonzini <pbonzini@redhat.com>"
# gpg:                 aka "Paolo Bonzini <bonzini@gnu.org>"

* remotes/bonzini/tags/for-upstream:
  memory: Lazy init name from QOM name as needed
  xen: hvm: Abstract away memory region name ref
  xen-hvm: Constify string
  virtio-scsi: Report error if num_queues is 0 or too large
  scsi-generic: remove superfluous DPRINTF avoid to break compiling
  block/iscsi: fix memory corruption on iscsi resize
  scsi-bus: Convert DeviceClass init to realize
  block: Pass errp in blkconf_geometry
