Fam Zheng c1958e9d54 docker: Improved image checksum When a base image locally defined by QEMU, such as in the debian images, is updated, the dockerfile checksum mechanism in docker.py still skips updating the derived image, because it only looks at the literal content of the dockerfile, without considering changes to the base image. For example we have a recent fix `e58c1f9b35` that fixed debian-win64-cross by updating its base image, debian8-mxe, but due to above "feature" of docker.py the image in question is automatically NOT rebuilt unless you add NOCACHE=1. It is noticed on Shippable: https://app.shippable.com/github/qemu/qemu/runs/541/2/console because after the fix is merged, the error still occurs, and the log shows the container image is, as explained above, not updated. This is because at the time docker.py was written, there wasn't any dependencies between QEMU's docker images. Now improve this to preprocess any "FROM qemu:*" directives in the dockerfiles while doing checksum, and inline the base image's dockerfile content, recursively. This ensures any changes on the depended _QEMU_ images are taken into account. This means for external images that we expect to retrieve from docker registries, we still do it as before. It is not perfect, because registry images can get updated too. Technically we could substitute the image name with its hex ID as obtained with $(docker images $IMAGE --format="{{.Id}}"), but --format is not supported by RHEL 7, so leave it for now.
