       Replace readdir_r to readdir
       
       Function `readdir_r` seems to be deprecated in favor of `readdir`.
       Replace the calls to avoid compile-time warnings.
       
       Minor code-style changes + additional note by me:
       
       POSIX says:
       
       "The pointer returned by readdir() points to data which may be overwritten by
       another call to readdir() on the same directory stream. This data is not
       overwritten by another call to readdir() on a different directory stream."
       
       https://pubs.opengroup.org/onlinepubs/009695399/functions/readdir_r.html
       
       So the nested readdir() is safe here.
