From: Elijah Newren <newren@xxxxxxxxx>
This continues the migration of the directory rename detection code into
diffcore-rename, now taking the simple step of combining it with the
dir_rename_info struct. Future commits will then make dir_rename_counts
be computed in stages, and add computation of dir_rename_guess.
