Subject: [PATCH] Use VIR_ALLOC_VAR instead of VIR_ALLOC_N for creating
 virObject

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.
