Non-at functions can be implemented by just calling the corresponding at function with AT_FDCWD and zero at_flags. In the linkat case, the at behavior is different (O_NOLINK), so this introduces __linkat_common to pass O_NOLINK as appropriate. lstat functions can also be implemented with fstatat by adding __fstatat64_common which takes a flags parameter in addition to the at_flags parameter, In the end this factorizes chmod, chown, link, lstat64, mkdir, readlink, rename, stat64, symlink, unlink, utimes. This also makes __lstat, __lxstat64, __stat and __xstat64 directly use __fstatat64_common instead of __lstat64 or __stat64.
