Rollup merge of #78499 - SkiFire13:fix-string-retain, r=m-ou-se 
Prevent String::retain from creating non-utf8 strings when abusing panic

Fixes #78498

The idea is the same as `Vec::drain`, set the len to 0 so that nobody can observe the broken invariant if it escapes the function (in this case if `f` panics)

Rollup merge of #75078 - ijackson:slice-strip, r=steveklabnik 
Improve documentation for slice strip_* functions

Prompted by the stabilisation tracking issue #73413 I looked at the docs for `strip_prefix` and `strip_suffix` for both `str` and `slice`, and I felt they could be slightly improved.

Thanks for your attention.

fix Box::into_unique

https://github.com/rust-lang/rust/pull/77187/ broke Stacked Borrows pointer tagging around `Box::into_unique` (this is caused by `Box` being a special case in the type system, which box-internal code needs to account for). This PR fixes that.

90e6d0d46b Auto merge of #75671 - nathanwhit:cstring-temp-lint, r=oli-obk 
Uplift `temporary-cstring-as-ptr` lint from `clippy` into rustc

The general consensus seems to be that this lint covers a common enough mistake to warrant inclusion in rustc.
The diagnostic message might need some tweaking, as I'm not sure the use of second-person perspective matches the rest of rustc, but I'd like to hear others' thoughts on that.

(cc #53224).

511fe048b4 Changed lint to check for std::fmt::Pointer and transmute 
The lint checks arguments in calls to `transmute` or functions that have
`Pointer` as a trait bound and displays a warning if the argument is a function
reference. Also checks for `std::fmt::Pointer::fmt` to handle formatting macros
although it doesn't depend on the exact expansion of the macro or formatting
internals. `std::fmt::Pointer` and `std::fmt::Pointer::fmt` were also added as
diagnostic items and symbols.

Rollup merge of #78394 - rubik:master, r=m-ou-se 
fix(docs): typo in BufWriter documentation

This PR fixes a small typo in the BufWriter documentation. The current documentation looks like this:

![2020-10-26-111501_438x83_scrot](https://user-images.githubusercontent.com/238549/97160357-83d3a000-177c-11eb-8a35-3cdd3a7d89de.png)

The `<u8>` at the end is mangled by Markdown. This PR makes the `BufWriter` documentation like the `BufReader` one:

https://github.com/rust-lang/rust/blob/master/library/std/src/io/buffered/bufreader.rs#L16

I'm tagging Steve as per the Rustc dev guide.

Rollup merge of #76635 - scottmcm:slice-as-chunks, r=LukasKalbertodt 
Add [T]::as_chunks(_mut)

Allows getting the slices directly, rather than just through an iterator as in `array_chunks(_mut)`.  The constructors for those iterators are then written in terms of these methods, so the iterator constructors no longer have any `unsafe` of their own.

Unstable, of course. #74985
