virtio: Add support for guest setting of queue size

The MMIO virtio transport spec allows the guest to tell the host how

Support virtio transports which can specify the vring alignment
(ie where the guest communicates this to the host) by providing

dataplane: sync virtio.c and vring.c virtqueue state

Load the virtio.c state into vring.c when we start dataplane mode and

memory: make section size a 128-bit integer

So far, the size of all regions passed to listeners could fit in 64 bits,
