vmstate: Allow dynamic allocation for VBUFFER during migration
This extends use of VMS_ALLOC flag from arrays to VBUFFER as well. This defines VMSTATE_VBUFFER_ALLOC_UINT32 which makes use of VMS_ALLOC and uses uint32_t type for a size. Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> Signed-off-by: Juan Quintela <quintela@redhat.com>
