(+ 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)

unallocated_blocks_are_zero field from BlockDriverInfo
- Fix qcow2 preallocation when the image size is not a multiple of the
cluster size

This means that when we resume a serialised request, it is running in
