Rob Bradford 3f02ccaa8c qcow: Add support for QCOW v2 header
The QCOW2 format is documented here:
https://git.qemu.org/?p=qemu.git;a=blob;f=docs/interop/qcow2.txt;hb=HEAD

The only difference between v2 and v3 is the addition of some extra
fields into the header in v3 for which there are default values in v2.

This introduces a new unit test for the behaviour but it has been
manually verified by the converting the image from v3 to v2
with a command like:

qemu-img convert -O qcow2 -o compat=0.10 clear-29620-cloud.img clear-29620-cloud.img.v2
