let mut iter = s.splitn(2, ' ');
let key = iter.next().unwrap();
let value = iter.next()?;
```
Suggestions on other patterns to check for would be useful. I've done a search on github for uses of `splitn`. Still have yet to actually look through the results.
There's also the question of whether the lint shouold trigger on all uses of `splitn` with two values, or only on recognized usages. The former could have false positives where it couldn't be replaced, but I'm not sure how common that would be.

Small documentation update for the new metadata_collector
Just small documentation updates after the merge of the new metadata collection. I'm also here to deliver on the promised fairy tale:
*Once upon a time, there was a world with many languages. One of the oldest was C a very versatile language that gave great power for the cost of great complexity and manual work. C was so powerful that it was able to create new languages. There is Java a versatile language often used by companies and in formal settings. Python that focused on readability and rapid prototyping capabilities. JavaScript which has some interesting edge cases but was still loved and widely used in the world. Together they build the foundation of our world and continue to shape the interactions between kingdoms worldwide.*
*C ruled as the king of Linux and other operating systems alongside the Queen C++. Together they were powerful leaders, in fact so powerful that they have been ruling this world for over 49 years. They remain happy together and loved by the community. However, with great power comes great responsibility! The two of them have a dark secret. To tell the truth, they sometimes suffer from memory loss and even worse in some instances from race conditions.*
*A mystical creature called Firefox lead to the creation of Mozilla, a global organization fighting for privacy and for their market share in the browser marked. As part of this fight, they started to modify parts of Firefox and eventually created Servo. A completely new creature with a new language called Rust. This new form of communication was focussed on correctness, speed and a new model of memory management.*
*Rust grew up over several years with modification to syntax, content among other things. Finally, in 2015 Rust has reached adulthood which enabled it to take part in the global discourse and shape the future of our world. Some even say that this was the start of a new area withing language design.*
*Rust had already started to build its kingdom and was now the head of a complete organization, with teams being in charge of individual tools used for further development. One team focussing on further improving Rust when it comes to complexity, style and performance was **The Clippy Team**. Its members were a friendly bunch, with mages and wizards among them.*
*With the goal of giving more power to Rust, they identified a Python tool inside Clippy that could be rewritten. This led to the creating of the **Metadata collection monster**. This monster soon replaced the old Python tool and allowed for new creative additions inside Clippy's lint list. With the eradication of the old tool, there came a possibility to update the configuration documentation to span over a lager area. This was done, but some doc comments remained until now in memory of the old tool. This is now the PR that removes these doc comments.*

Auto merge of #7521 - rukai:fix_lintcheck_local_path_handling, r=camsteffen
lintcheck always copies in a fresh crate when provided with a crate path
changelog: none
When lintcheck is run on local crates it copies the crate to `target/lintcheck/sources/crate_name` on the first run only.
Then in subsequent runs of lintcheck it reuses this same copy.
This caching behaviour makes sense when dealing with immutable crates.io releases and git commits.
However it is quite surprising that the changes to my local crate are not used when I run lintcheck.
To fix this I removed the copy, instead clippy runs directly off the provided crate folder.
I have tested this and have not observed any negative effects from doing this.
But maybe i'm missing something as im not familiar with clippy!
Alternatively we could make it copy the entire crate every run, but that seems problematic to me as multi-gigabyte target folders will take a long time to copy and wear down SSDs for developers who frequently run lintcheck.

Auto merge of #7568 - dtolnay-contrib:ifletelse, r=llogiq
Downgrade option_if_let_else to nursery
I believe that this lint's loose understanding of ownership (#5822, #6737) makes it unsuitable to be enabled by default in its current state, even as a pedantic lint.
Additionally the lint has known problems with type inference (#6137), though I may be willing to consider this a non-blocker in isolation if it weren't for the ownership false positives.
A fourth false positive involving const fn: #7567.
But on top of these, for me the biggest issue is I basically fully agree with https://github.com/rust-lang/rust-clippy/issues/6137#issuecomment-705605688. In my experience this lint universally makes code worse even when the resulting code does compile.

* Copy types are correctly borrowed by reference when their value is used

Now a small informal explanation what this PR changes (just for fun):
* *Once upon a time there was a monster. It was handsome, supportive and happy to dig through the best source code it has ever seen. Spanning over hundreds of lines and reading over complete crates, it was purely marvels!*
*However, there was one region in its territory that wasn't clean and well formatted like the rest. That was the mighty `define_Conf` macro. The monster would have cleaned it up a long time ago but, the previous ruler of this kingdom a powerful Python script was prohibiting it. But now that the old king was slain in the great battle of rust-1.54.0, everything was possible again. Our lovely monster was now able to grab its cleaning equipment and get some nice formatting into the now unprotected area.*
*Said and done! Let this day go down in history!*
(I'll be the first to admit, that I'm a bit lost today. And I'm also procrastinating on some other discussions where I have some catching up to do... Oh, well, this was fun)

Make `SEMICOLON_IN_EXPRESSIONS_FROM_MACROS` warn by default
This PR makes the `SEMICOLON_IN_EXPRESSIONS_FROM_MACROS` lint warn by default.
To avoid showing a large number of un-actionable warnings to users, we only enable the lint for macros defined in the same crate. This ensures that users will be able to fix the warning by simply removing a semicolon.
In the future, I'd like to enable this lint unconditionally, and eventually make it into a hard error in a future edition. This PR is a step towards that goal.

Moving on, there were a few things that I was unsure about:
* The PR rust-lang/rust#86717 changes an old entry in the change log, is this worth mentioning? I've left it out for now.
* The stabilization of `cargo clippy --fix` is quite awesome and important IMO. It sadly gets a bit lost in the *Other* entry, as it's the last one. Do we maybe want to move it somewhere else or change the headline order for this release?
* I've listed the introduction of the new `suspicious` group under the *Moves and Deprecations* section. Is this alright, or should it be moved to the *Other* section as well?
* Last but definitely not least, some fun! I've used the :tada: emoji in the `cargo clippy --fix` entry, is this okay?
Sorry for the bombardment of questions xD

The PR already includes the entries for the new metadata collection and website updates. These are not merged yet, but should probably be to make this correct. This might also require the commit hashes to be updated (Not sure on this, though). It would actually be super fitting to get this into this release as we also stabilize `--fix`. TODOs:
* [x] Merge metadata collection PRs:
1. #7279
2. #7298
3. #7420 (Hope to not get any merge conflicts)
