wrong_self_convention: fix lint in case of `to_*_mut` method
fixes#6758
changelog: wrong_self_convention: fix lint in case of `to_*_mut` method. When a method starts with `to_` and ends with `_mut`, clippy expects a `&mut self` parameter, otherwise `&self`.
Any feedback is welcome. I was also thinking if shouldn't we treat `to_` the same way as `as_`. Namely to accept `self` taken: `&self` or `&mut self`.
Move some utils to `clippy_utils::ty`
changelog: none
`clippy_utils::*` has become a giant junk drawer. This is one step to clean it up a bit. One motivation is that I believe the long import statements cause more merge conflicts.
replace span_lint with span_lint_and_sugg along with error message
fixes: #6874
changelog: none
apologies if this may not be the most idiomatic way of doing it, any advice on changes (if any) would be greatly appreciated.
mem_replace_with_default: recognize some std library ctors
fixes#6562
changelog: mem_replace_with_default: recognize some common constructors equivalent to `Default::default()`
Fix suggestion for `explicit_deref_methods`. Sometimes `&**` is needed, sometimes nothing is needed.
Allow `explicit_deref_methods` to trigger in a few new contexts.
`explicit_deref_methods` will now consider ufcs calls

Use sym::Iterator instead of paths::ITERATOR
Since `sym::Iterator` was added to diagnostic_item, it's time to remove `paths::ITERATOR`.

Refactor: arrange lints in `methods` module
This PR arranges methods lints so that they can be accessed more easily.
Basically, I refactored them following the instruction described in #6680.
changelog: Move lints in methods module into their own modules.
move lintcheck into its own crate
This pr:
* moves lintcheck out of `clippy dev` and into its own crate (`lintcheck`) (I should have done this earlier :D)
* makes lintcheck terminate if it is not launched from the repo root (to prevent problems with wrong paths when using `cargo run` in the crate root)
* fixes json lint messages leaking the runners `$HOME` when a lint messages comes from a proc macro that originates from a crate inside the `$CARGO_CACHE`
* adds more documentation to lintchecks `README.md` and mentions lintcheck in `docs/basics.md`
