qemu-iotests: add 036 autoclear feature bit test
This new test validates the autoclear feature bit behavior. When QEMU opens a qcow2v3 image file with an unknown autoclear feature bit the bit should be cleared in the image file header. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
