Replace usage of opendir/readdir/closedir API to traverse directories recursively, at copy_or_link_directory function, by the dir-iterator API. This simplifies the code and avoids recursive calls to copy_or_link_directory. This process also makes copy_or_link_directory call die() in case of an error on readdir or stat, inside dir_iterator_advance. Previously it would just print a warning for errors on stat and ignore errors on readdir, which isn't nice because a local git clone could succeed even though the .git/objects copy didn't fully succeed.
