[Qemu-devel] [PULL 01/26] qcow2: Change default for new images to compat=1.1 |

By the time that qemu 1.7 will be released, enough time will have passed
since qemu 1.1, which is the first version to understand version 3
images, that changing the default shouldn't hurt many people any more
and the benefits of using the new format outweigh the pain.
qemu-iotests already runs with compat=1.1 by default.
