  scandir(3) previously used st_size to obtain an initial estimate
  of the array length needed to store all the directory entries.
  Although BSD has historically guaranteed that st_size is the size
  of the directory file, POSIX does not, and more to the point, some
  recent filesystems such as ZFS use st_size to mean something else.
  The fix is to not stat the directory at all, set the initial
  array size to 32 entries, and realloc it in powers of 2 if that
  proves insufficient.
