nbd: Allow export of multiple bitmaps for one device
With this, 'qemu-nbd -B b0 -B b1 -f qcow2 img.qcow2' can let you sniff out multiple bitmaps from one server. qemu-img as client can still only read one bitmap per client connection, but other NBD clients (hello libnbd) can now read multiple bitmaps in a single pass.
