Disable topological sorting in PackWriter
Its not strictly required that we sort topologically in order to produce a valid pack file. This was just something that Linus thought would be a good idea to do. In practice its not that important for most repositories. Local file IO quickly falls out of the pattern that topological sorting provides any sort of benefit for, so expending extra resources to enforce it when we make a pack isn't really worth it. I'm removing this sort in the pipeline because later changes would support really efficient COMMIT_TIME_DESC sorting on a non-file storage system, but TOPO sorting would be a bit more ugly to run, due to the in-memory delays it imposes.
