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

Rather than relying on shared memory for a temporary file for QCOW
testing instead use tempfile crate to get a temporary file. The vector
cache tests also need a trivial update after the refactor.
