Turns out there's one callback that might remove a storage pool
during its run: storagePoolUpdateAllState() call
storagePoolUpdateStateCallback() which may call
virStoragePoolUpdateInactive() which in turn may call
virStoragePoolObjRemove(). Problem is that the
UpdateStateCallback() sees a storage pool object with just two
references: one for each hash table holding the object. If the
function ends up calling ObjRemove() then upon removing the
object from hash tables those references are gone and thus any
subsequent call touching the object is invalid.

The solution to this problem is to grab reference for the object
we are running iterator with.

It may happen that we leave some XATTRs behind. For instance, on
a sudden power loss, the host just shuts down without calling
restore on domain paths. This creates a problem, because when the
host starts up again, the XATTRs are there but they don't reflect
the true state and this may result in libvirt denying start of a
domain.

To solve this, save a unique timestamp (host boot time) among
with our XATTRs.

If user has two domains, each have the same disk (configured for
RW) but each runs with different seclabel then we deny start of
the second domain because in order to do that we would need to
relabel the disk but that would cut the first domain off. Even if
we did not do that, qemu would fail to start because it would be
unable to lock the disk image for the second time. So far, this
behaviour is expected. But what is not expected is that we
increase the refcounter in XATTRs and leave it like that.

What happens is that when the second domain starts,
virSecuritySetRememberedLabel() is called, and since there are
XATTRs from the first domain it increments the refcounter and
returns it (refcounter == 2 at this point). Then callers
(virSecurityDACSetOwnership() and
virSecuritySELinuxSetFileconHelper()) realize that refcounter is
greater than 1 and desired seclabel doesn't match the one the
disk image already has and an error is produced. But the
refcounter is never decremented.
