What's in 1.29.1 stable

A security vulnerability was found in the standard library where if a large number was passed to str::repeat it could cause a buffer overflow after an integer overflow. If you do not call the str::repeat function you are not affected. This has been addressed by unconditionally panicking in str::repeat on integer overflow. More details about this can be found in the security announcement.
