copies-rust: leverage the immutability for efficient update The immutable OrdMap has a diff function. That function yield items for each difference (missing in minor; missing in major; present in both, but different). We reorganise the manifest merging code to use this new function. We gather the data we would need to inject into the `minor` or `major` dict and eventually update one of them. The semantic of the merge itself is kept as is. Why are we doing this? Last year we contributed a patch making that diff function quickly detect some of the identical subsection when comparing two OrdMap cloned from a common ancestors (because they point to the very same node in memory). As a result: - That diff function is very fast in most of our cases, - It is important to maximize the "common" part by minimising the amount of unnecessary changes we do in theses Map. This is why we gather update for both and update the one with the smaller update. In practice, this yield a massive speed up on all our slow cases.
