It was never implemented and for now I don't think there's demand to do
it. Remove the reference.

I think we should implement block, rather than delete it. It matters for the same reason that it matters in the destination of block copy: if you want to set a highest-byte watermark threshold (to be warned by qemu when it is time to resize the disk larger), you NEED a block device, not a file. But libvirt treats all <disk type='file'> as files, even when opening /path/to/device; you HAVE to use <disk type='block'> when specifying a block device to get the behaviors needed for handling it as a block device rather than a file.

                  Similar to a disk declaration for a domain, the choice of type
                  controls what additional sub-elements are needed to describe

I'm inclined to NACK this patch.
