  qcow2: add discard-no-unref option (2023-06-05 13:15:42 +0200)

----------------------------------------------------------------
Block patches

- Fix padding of unaligned vectored requests to match the host alignment
  for vectors with 1023 or 1024 buffers
- Refactor and fix bugs in parallels's image check functionality
- Add an option to the qcow2 driver to retain (qcow2-level) allocations
  on discard requests from the guest (while still forwarding the discard
  to the lower level and marking the range as zero)
