 * This revision is what German speakers call "das Tüpfelchen auf dem I".  "The
   icing on the cake" is the English equivalent.  Since I like cake and don't
   want it to be half-baked, and because I like my metaphors shaken, not
   stirred, I went ahead with the extra revision so I could write this message.
 * Use g_autoptr(QCryptoBlock) to make the code more concise [Max]
 * Use local_err consistently [Max]
 * Folded in Max's Reviewed-by tags
v3:
 * Move payload offset calculation function to crypto/block.c [Max]
 * Zero/unallocated blocks always require disk space on encrypted files [Max]
 * Update qemu-iotests 178 output when changing qemu-img measure command-line
   options

v2:
 * Fix uint64_t <-> size_t type mismatch in block_crypto_measure() so that
   32-bit builds pass

This patch series adds qemu-img measure support to the "luks" block driver.  We
just need to take into account the LUKS header when sizing the image.

Stefan Hajnoczi (4):
  luks: extract qcrypto_block_calculate_payload_offset()
  luks: implement .bdrv_measure()
  qemu-img: allow qemu-img measure --object without a filename
  iotests: add 282 luks qemu-img measure test
