diffcore-rename: move dir_rename_counts into dir_rename_info struct

Browse Source 
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.
