d5b6a20557 std: Don't abort process when printing panics in tests
This commit fixes an issue when using `set_print` and friends, notably
used by libtest, to avoid aborting the process if printing panics. This
previously panicked due to borrowing a mutable `RefCell` twice, and this
is worked around by borrowing these cells for less time, instead
taking out and removing contents temporarily.

Closes #69558

a5206f9749 add Option::{zip,zip_with} methods under "option_zip" gate
This commit introduces 2 methods - `Option::zip` and `Option::zip_with` with
respective signatures:
- zip: `(Option<T>, Option<U>) -> Option<(T, U)>`
- zip_with: `(Option<T>, Option<U>, (T, U) -> R) -> Option<R>`
Both are under the feature gate "option_zip".

I'm not sure about the name "zip", maybe we can find a better name for this.
(I would prefer `union` for example, but this is a keyword :( )

--------------------------------------------------------------------------------

Recently in a russian rust begginers telegram chat a newbie asked (translated):
> Are there any methods for these conversions:
>
> 1. `(Option<A>, Option<B>) -> Option<(A, B)>`
> 2. `Vec<Option<T>> -> Option<Vec<T>>`
>
> ?

While second (2.) is clearly `vec.into_iter().collect::<Option<Vec<_>>()`, the
first one isn't that clear.

I couldn't find anything similar in the `core` and I've come to this solution:
```rust
let tuple: (Option<A>, Option<B>) = ...;
let res: Option<(A, B)> = tuple.0.and_then(|a| tuple.1.map(|b| (a, b)));
```

However this solution isn't "nice" (same for just `match`/`if let`), so I thought
that this functionality should be in `core`.

Fix bugs in Peekable and Flatten when using non-fused iterators

I fixed a couple of bugs with regard to the `Peekable` and `Flatten`/`FlatMap` iterators when the underlying iterator isn't fused. For testing, I also added a `NonFused` iterator wrapper that panics when `next` or `next_back` is called on an iterator that has returned `None` before, which will hopefully make it easier to spot these mistakes in the future.

### Peekable

`Peekable::next_back` was implemented as
```rust
self.iter.next_back().or_else(|| self.peeked.take().and_then(|x| x))
```
which is incorrect because when the `peeked` field is `Some(None)`, then `None` has already been returned from the inner iterator and what it returns from `next_back` can no longer be relied upon. `test_peekable_non_fused` tests this.

### Flatten

When a `FlattenCompat` instance only has a `backiter` remaining (i.e. `self.frontiter` is `None` and `self.iter` is empty), then `next` will call `self.iter.next()` every time, so the `iter` field needs to be fused. I fixed it by giving it the type `Fuse<I>` instead of `I`, I think this is the only way to fix it. `test_flatten_non_fused_outer` tests this.

Furthermore, previously `FlattenCompat::next` did not set `self.frontiter` to `None` after it returned `None`, which is incorrect when the inner iterator type isn't fused. I just delegated it to `try_fold` because that already handles it correctly. `test_flatten_non_fused_inner` tests this.

implement zeroed and uninitialized with MaybeUninit

This is the second attempt of doing such a change (first PR: https://github.com/rust-lang/rust/pull/62150). The last change [got reverted](https://github.com/rust-lang/rust/pull/63343) because it [caused](https://github.com/rust-lang/rust/issues/62825) some [issues](https://github.com/rust-lang/rust/issues/52898#issuecomment-512182438) in [code that incorrectly used these functions](https://github.com/erlepereira/x11-rs/issues/99).

Since then, the [problematic code has been fixed](https://github.com/erlepereira/x11-rs/pull/101), and rustc [gained a lint](https://github.com/rust-lang/rust/pull/63346) that is able to detect many misuses of these functions statically and a [dynamic check that panics](https://github.com/rust-lang/rust/pull/66059) instead of causing UB for some incorrect uses.
