update lifetime-elision to show what elided code under `rust_2018_idi… ( #306 )
...
This was a bit confusing for me to read, as it was using an old style of rust that I am not used to
Unfortunately, this lint group isn't on by default, but I think `elided_lifetimes_in_paths` may be on track to be deny-by-default in edition 2021?

Document lifetime elision for fn types, Fn*, impl
...
Currently, the lifetime elision doc only documents function definitions, but lifetime elision is also allowed in the following other locations:
* `fn` types, such as `fn(&T)`
* `Fn`/`FnMut`/`FnOnce`, such as `Fn(&T)`
* `impl` headers
To demo this up, I made some type aliases for `fn`/`Fn` which you can pass `&T` as a parameter to (to follow the lifetime rules of the surrounding context), and compared what you get with that instead of using `fn`/`Fn` directly, where lifetime elision takes on the rules from `fn`/`Fn`/etc.
I also demoed up an `impl` header that used lifetime elision twice, although the error message in that case is broken (filed https://github.com/rust-lang/rust/issues/87763 )
The demo was half for this change description, and half just to make sure I understand Rust -- in particular, I really had to reverse engineer it for `impl` because I wasn't sure, and it didn't seem to be documented anywhere (at least not here!)

Update link to c++ atomic ordering docs ( #264 )

I'm not sure if this is actually desirable. For one thing, the link I used isn't
locked to c++20 exactly. But it is the same page the [std lib](https://doc.rust-lang.org/std/sync/atomic/enum.Ordering.html ) links to
so that may be good for something.
I'm also not sure if other references to `C++11` should be updated or removed.
Basically, I feel like _something_ should change here but I'm not really sure what :-\

This is a squash of the following commits:
- Fix code, remove WIP message as that was while writing this, and link to stable @ fixed 1.49 rather than latest nightly
- Improve wording on deref and ignore some code blocks
- Improve wording and formatting a bit cause I'm insane
- Fix links
- Fix links again because we all love relative links
- Remove unnecessary Drop import
- Use Box::from_raw instead of ptr::drop_in_place as that actually dealloc's the Box (i'm dumb and misinterpreted the std code :/); fix some desync between code in between sections
- Fix tests
