[libvirt] [PATCH 3/7] Use VIR_ALLOC_VAR instead of VIR_ALLOC_N for creating virObject

From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; The current way virObject instances are allocated using VIR_ALLOC_N causes alignment warnings util/virobject.c: In function 'virObjectNew': util/virobject.c:195:11: error: cast increases required alignment of target type [-Werror=cast-align] Changing to use VIR_ALLOC_VAR will avoid the need todo the casts entirely.
