This series fixes various issues spotted by Coverity. None of these is critical; most are just "If you do something crazy, qemu-img crashes" or "But what if there is no qcow2 driver?". Therefore, while these are bug fixes, it is a bit late to try to push them into 2.2.0. I am therefore tempted to vote to target 2.3 instead.
Also, none is security-relevant. The only crashes which are fixed here are sure to have resulted from dereferencing a NULL pointer.
