weak alias.

* dirent/readdir_r.c: Removed. We indeed need a real implementation.
* sysdeps/unix/readdir_r.c: New file.
* sysdeps/unix/readdir.c: Remove check for correct parameter
values. Let them simply die.
* manual/filesys.texi: Document readdir_r.
* sysdeps/gnu/errlist.awk: Define _sys_errlist as `const char* const'.
