Automatically create QCoW2 images as needed on startup

Snapshots in QEMU 2 work only as long as images in QCoW2
format are used. It is a copy-on-write format that stores diffs
to a backing image.
This change makes it so that the emulator creates the necessary
QCoW2 images (backed by the raw images specified in AVD config)
automatically.
The QCoW2 images are re-created (and snapshots obliterated) if
the user wipes AVD's data or it is detected that the system image
has been updated to another version.
