CVE-2013-4237, BZ #14699: Buffer overflow in readdir_r
* sysdeps/posix/dirstream.h (struct __dirstream): Add errcode member. * sysdeps/posix/opendir.c (__alloc_dir): Initialize errcode member. * sysdeps/posix/rewinddir.c (rewinddir): Reset errcode member. * sysdeps/posix/readdir_r.c (__READDIR_R): Enforce NAME_MAX limit. Return delayed error code. Remove GETDENTS_64BIT_ALIGNED conditional. * sysdeps/unix/sysv/linux/wordsize-64/readdir_r.c: Do not define GETDENTS_64BIT_ALIGNED. * sysdeps/unix/sysv/linux/i386/readdir64_r.c: Likewise. * manual/filesys.texi (Reading/Closing Directory): Document ENAMETOOLONG return value of readdir_r. Recommend readdir more strongly. * manual/conf.texi (Limits for Files): Add portability note to NAME_MAX, PATH_MAX. (Pathconf): Add portability note for _PC_NAME_MAX, _PC_PATH_MAX.
