Rewrite the backend for displaying the history of an image to simplify the code and be closer to docker's behaviour. Instead of driving index-based heuristics, create a reverse mapping from top-layers to the corresponding image IDs and lookup the layers on-demand. Also use the uncompressed layer size to be closer to Docker's behaviour. Note that intermediate images from local builds are not considered for the ID lookups anymore. Fixes: #3359 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
