There are few helpers already to support array migration. However they all require the destination side to preallocate arrays before migration which is not always possible due to unknown array size as it might be some sort of dynamic state. One of the examples is an array of MSIX-enabled devices in SPAPR PHB - this array may vary from 0 to 65536 entries and its size depends on guest's ability to enable MSIX or do PCI hotplug. This adds new VMSTATE_VARRAY_STRUCT_ALLOC macro which is pretty similar to VMSTATE_STRUCT_VARRAY_POINTER_INT32 but it can alloc memory for migratign array on the destination side. This defines VMS_ALLOC flag for a field. This changes vmstate_base_addr() to do the allocation when receiving migration.
