  vhost: Add vhost_commit callback for SeaBIOS ROM region re-mapping

This patch follows MST's recommendation to move checks for
vhost_verify_ring_mappings() -> cpu_physical_memory_map() operations
from MemoryListener->region_[add,del]() -> vhost_set_memory() into
final MemoryListener->commit() -> vhost_commit() callback.

It addresses the case where virtio-scsi vq ioport RAM re-mapping
to read-only SeaBIOS ROM triggers a cpu_physical_memory_map()
NIL MemoryRegionSection pointer failure.

Also save vhost_dev->mem_changed_[start,end]_addr values in
vhost_set_memory() for final ranges_overlap checks.  (Thanks Paolo!)

Executing this command could not let Windows guest panic, it caused by
the wrong order of releasing keys. This problem was introduced by
commit e4c8f004c55d9da3eae3e14df740238bf805b5d6.

The right release order should be starting from last item.

  virtio-balloon: fix integer overflow in BALLOON_CHANGE QMP event

Because dev->actual is uint32_t, the expression 'dev->actual <<
VIRTIO_BALLOON_PFN_SHIFT' is truncated to 32 bits. This overflows when
dev->actual >= 1048576.

To reproduce:

 1. Start a VM with a QMP socket and 5G of RAM
 2. Connect to the QMP socket, negotiate capabilities and issue:

   { "execute":"balloon", "arguments": { "value": 1073741824 } }

 3. Watch for BALLOON_CHANGE QMP events, the last one will incorretly be:

   { "timestamp": { "seconds": 1366228965, "microseconds": 245466 },
     "event": "BALLOON_CHANGE", "data": { "actual": 5368709120 } }

To fix it this commit casts it to ram_addr_t, which is ram_size's type.

  vhost-scsi: new device supporting the tcm_vhost Linux kernel module

The WWPN specified in configfs is passed to "-device vhost-scsi-pci".
The tgpt field of the SET_ENDPOINT ioctl is obsolete now, so it is not
available from the QEMU command-line.  Instead, I hardcode it to zero.

Changes in Patch-v2:
   - Add vhost_scsi_get_features() in order to determine feature bits
     supports by host kernel (mst + nab)
   - Re-enable usage of DEFINE_VIRTIO_COMMON_FEATURES, and allow
     EVENT_IDX to be disabled by host in vhost_scsi_get_features()
   - Drop unused hotplug bit in DEFINE_VHOST_SCSI_PROPERTIES

Changes in Patch-v1:
   - Set event_idx=off by default (nab, thanks asias)
   - Disable hotplug feature bit for v3.9 tcm_vhost kernel code, need to
     re-enable in v3.10 (nab)
   - Update to latest qemu.git/master HEAD

Changes in WIP-V3:
   - Drop ioeventfd vhost_scsi_properties (asias, thanks stefanha)
   - Add CONFIG_VHOST_SCSI (asias, thanks stefanha)
   - Add hotplug feature bit

Changes in WIP-V2:
   - Add backend guest masking support (nab)
   - Bump ABI_VERSION to 1 (nab)
   - Set up set_guest_notifiers (asias)
   - Set up vs->dev.vq_index (asias)
   - Drop vs->vs.vdev.{set,clear}_vhost_endpoint (asias)
   - Drop VIRTIO_CONFIG_S_DRIVER check in vhost_scsi_set_status (asias)

Howto:
   Use the latest seabios, at least commit b44a7be17b
   git clone git://git.seabios.org/seabios.git
   make
   cp out/bios.bin /usr/share/qemu/bios.bin

Options starting in "backing." are passed to the backing file now. If

$ qemu-nbd -t /tmp/test.img

$ qemu-system-x86_64 -drive file=empty.qcow2,backing.file.driver=nbd,\
    backing.file.host=localhost

Note that this doesn't override the backing filename from the image. If
the image has one, this will fail because NBD doesn't want the options
and a filename at the same time.

This allows using the file.filename option instead of the string that

The goal is to get rid of this parameter and use the options QDict more
consistently.

With this option you can access not only the top-level image, but
specify a filename for the backing file (currently only if no backing
file exists, but we'll allow overriding it later)

  curl: Use bdrv_open options instead of filename

As a bonus, going through the QemuOpts QEMU_OPT_SIZE parser for the
readahead option gives us proper error reporting that the previous use
of atoi() lacked.

  gluster: Use bdrv_open options instead of filename

This is only to convert the internal interface that is used for passing
the "filename" to be parsed, but converting to actual fine grained
options is left for another day, as it doesn't look trivial.

  qemu-iotests: add 053 unaligned compressed image size test

Test that qemu-img convert -c works when input image length is not a
multiple of the cluster size.

Previously an error message would be produced:

  qemu-img: error while compressing sector 0: Input/output error

Now that qcow2 and qcow handle this case the test passes successfully.
