be0125bed4 Auto merge of #6469 - matthiaskrgr:clippy_dev_crater, r=flip1995 
add "cargo dev crater" to run clippy on a fixed set of crates and diff the lint warnings

`cargo dev crater` now does the following:
build clippy in debug mode
for a fixed set of crates:
 download and extract the crate
 run compiled clippy on the crate
 dump the warnings into a file that is inside the repo

We can then do a "git diff" and see what effects our clippy changes had on a tiny fraction of the rust ecosystem and can see when an change unexpectedly added or silenced a lot of warnings.

Checking all the crates took less than 5 minutes on my system.

Should help with https://github.com/rust-lang/rust-clippy/issues/6429

Documentation for adding configuration to a lint and common abbreviations

This PR adds some commonly used abbreviations to the `basis.md` file and a guide on how to implement a configuration value for a lint.

* [Rendered `/doc/basics.md` (Abbreviation list)](https://github.com/xFrednet/rust-clippy/blob/0000-configuration-documentation/doc/basics.md#common-abbreviations)
* [Rendered `/doc/adding_lints.md` (Configuration value guide)](https://github.com/xFrednet/rust-clippy/blob/0000-configuration-documentation/doc/adding_lints.md#adding-configuration-to-a-lint)

I'm not sure if the guide is written in the best way. Style suggestions are appreciated. 🙃

Again a big **thank you** for everyone who helped to collect the abbreviation list over on [zulip]. I had a lot of fun, and it was also very informative. Keep up the good work 🙃

Similar names ignore underscore prefixed names

changelog: Ignore underscore-prefixed names for similar_names

IMO, this lint is not very helpful for underscore-prefixed variables. Usually they are unused or are just there to ignore part of a destructuring.

changelog: Add `manual_filter_map` and replace `find_map` with `manual_find_map`

Replaces #6453

Fixes #3188
Fixes #4193

~Depends on #6567 (to fix an internal lint false positive)~

This replaces `filter_map` and `find_map` with `manual_filter_map` and `manual_find_map` respectively. However, `filter_map` is left in place since it is used for a variety of other cases. See discussion in #6453.

e9b2cf4f64 Rollup merge of #81236 - estebank:everybody-loop-now, r=oli-obk 
Gracefully handle loop labels missing leading `'` in different positions

Fix #81192.

* Account for labels when suggesting `loop` instead of `while true`
* Suggest `'a` when given `a` only when appropriate
* Add loop head span to hir
* Tweak error for invalid `break expr`
* Add more misspelled label tests
* Avoid emitting redundant "unused label" lint
* Parse loop labels missing a leading `'`
