Merge remote-tracking branch 'remotes/maxreitz/tags/pull-block-2020-07-06' into staging
Block patches for 5.1:
- LUKS keyslot amendment
(+ patches to make the iotests pass on non-Linux systems, and to keep
the tests passing for qcow v1, and to skip LUKS tests (including
qcow2 LUKS) when the built qemu does not support it)
- Refactoring in the block layer: Drop the basically unnecessary
unallocated_blocks_are_zero field from BlockDriverInfo
- Fix qcow2 preallocation when the image size is not a multiple of the
cluster size
- Fix in block-copy code
