This patch is a straightforward refactoring of libnbd?s nbdcopy program, and not very interesting. However I have plans for nbdcopy (see full todo below). I would like to use this utility for virt-v2v as a replacement for ?qemu-img convert?. qemu-img has caused us a series of problems: - change in zeroing behaviour caused a big performance regression - qemu-img reads extents up-front which
