range-diff: first rudimentary implementation At this stage, `git range-diff` can determine corresponding commits of two related commit ranges. This makes use of the recently introduced implementation of the linear assignment algorithm. The core of this patch is a straight port of the ideas of tbdiff, the apparently dormant project at https://github.com/trast/tbdiff. The output does not at all match `tbdiff`'s output yet, as this patch really concentrates on getting the patch matching part right. Note: due to differences in the diff algorithm (`tbdiff` uses the Python module `difflib`, Git uses its xdiff fork), the cost matrix calculated by `range-diff` is different (but very similar) to the one calculated by `tbdiff`. Therefore, it is possible that they find different matching commits in corner cases (e.g. when a patch was split into two patches of roughly equal length).
