In qemu_gluster_parse_json(), the call to qdict_array_entries()
could return a negative error code, which we were ignoring
because we assigned the result to an unsigned variable.
Fix this by using the 'int' type instead, which matches the
return type of qdict_array_entries() and also the type
we use for the loop enumeration variable 'i'.

external_snapshot_prepare() calling bdrv_replace_node() to swap the

The final bdrv_set_backing_hd() could be working on already freed nodes
because the commit job drops its references (through BlockBackends) to
both overlay_bs and top already a bit earlier.
One way to trigger the bug is hot unplugging a disk for which
blockdev_mark_auto_del() cancels the block job.
Fix this by taking BDS-level references while we're still using the
nodes.

Block migration may still access the image during its
.save_live_complete_precopy() implementation, so we should only
inactivate the image afterwards.
Another reason for the change is that inactivating an image fails when
there is still a non-device BlockBackend using it, which includes the
BBs used by block migration. We want to give block migration a chance to
release the BBs before trying to inactivate the image (this will be done
in another patch).

The cpu_setup() handler is only implemented by xics_kvm, where it really
does a typical "realize" job. Moreover, the realize() handler is called

Until recently, spapr used to allocate ICPState objects for the lifetime
of the machine. They would only be associated to vCPUs in xics_cpu_setup()
when plugging a CPU core.
Now that ICPState objects have the same lifecycle as vCPUs, it is
possible to associate them during realization.
This patch hence open-codes xics_cpu_setup() in icp_realize(). The vCPU
is passed as a property. Note that vCPU now needs to be realized first
for the IRQs to be allocated. It also needs to resetted before ICPState
realization in order to synchronize with KVM.
Since ICPState objects are freed when unrealized, xics_cpu_destroy() isn't
needed anymore and can be safely dropped.
