I think the part that the qcow2 block driver should be contributing is
just that it can automatically create an encryption layer if the image
file header contains a flag that this new encryption mechanism is used.
This way a similar interface as before could be provided, where the user
basically just says '-hda encrypted.qcow2' and qemu will ask for the
password.
