treemanifest: make diff() faster Containment checking is slower in treemanifest than it is in manifestdict, making the current diff algorithm O(n log n). By traversing both treemanifests in parallel, we can make it O(n). More importantly, once we start lazily loading submanifests, we will be able to easily skip entire submanifest if they have the same nodeid.
