copies-rust: add smarter approach for merging small mapping with large mapping...

copies-rust: add smarter approach for merging small mapping with large mapping The current approach (finding the smaller updated set) works great when the mapping have similar size, but do a lot of unnecessary work when one side is tinier than the other one. So we do better in theses cases. See inline documentation for details. It give a sizeable boost to many of out slower cases: Repo Case Source-Rev Dest-Rev # of revisions old time new time Difference Factor time per rev --------------------------------------------------------------------------------------------------------------------------------------------------------------- mozilla-try x00000_revs_x_added_0_copies 1ebb79acd503 : 363753 revs, 18.123103 s, 5.693818 s, -12.429285 s, × 0.3142, 15 µs/rev mozilla-try x00000_revs_x_added_x_copies 95d83ee7242d : 362229 revs, 17.907312 s, 5.677655 s, -12.229657 s, × 0.3171, 15 µs/rev mozilla-try x00000_revs_x000_added_x_copies ca82787bb23c : 359344 revs, 17.684797 s, 5.563370 s, -12.121427 s, × 0.3146, 15 µs/rev mozilla-try x00000_revs_x0000_added_x0000_copies eb884023b810 : 192665 revs, 2.881471 s, 2.864099 s, -0.017372 s, × 0.9940, 14 µs/rev mozilla-try x00000_revs_x00000_added_x000_copies 8e29777b48e6 : 382065 revs, 63.148971 s, 59.498652 s, -3.650319 s, × 0.9422, 155 µs/rev mozilla-try x00000_revs_x00000_added_x000_copies 8e29777b48e6 : 382065 revs, 63.148971 s, 59.498652 s, -3.650319 s, × 0.9422, 155 µs/rev ideally, the im-rs object would have a `merge` method, but it does not (yet) Full timing comparison below (they are one pathological case than become even worse, for unclear reason).
