Version 2.42

• virtnbdrestore: add --compress option: if enabled, NBD server used for
  restore will make use of the qcow compression driver. This way, restored
  data within the qcow image is compressed according to the image compression
  type setting. This will be beneficial for images that contained many compressed blocks, as
  the restored images will be way smaller. (#295)
