Update rust-analyzer documentation, mention linkedProjects
r-a uses the `rustc-dev` component from the rustup installed toolchain clippy specifies so it doesn't need to be manually installed. Also remove references to nightly r-a as the feature is long stable
I discovered `rust-analyzer.linkedProjects` recently and it has made working on the crates not referenced by the `clippy` crate so much nicer

Make module-style lints resilient to --remap-path-prefix
changelog: [`self_named_module_files`], [`mod_module_files`]: Make module-style lints resilient to `--remap-path-prefix`
Without this if a user has configured `--remap-path-prefix` to be used for a prefix containing the current source directory the lints would silently fail to generate a warning.
`bool_to_int_with_if` inverse case patch
Enhances `bool_to_int_with_if` such that it can also catch an inverse bool int conversion scenario, and makes the right suggestion for converting to int with a prefixed negation operator.
changelog: [`bool_to_int_with_if`]: Now correctly detects the inverse case, `if bool { 0 } else { 1 }`
Initial implementation of dyn*
This PR adds extremely basic and incomplete support for [dyn*](https://smallcultfollowing.com/babysteps//blog/2022/03/29/dyn-can-we-make-dyn-sized/). The goal is to get something in tree behind a flag to make collaboration easier, and also to make sure the implementation so far is not unreasonable. This PR does quite a few things:
* Introduce `dyn_star` feature flag
* Adds parsing for `dyn* Trait` types
* Defines `dyn* Trait` as a sized type
* Adds support for explicit casts, like `42usize as dyn* Debug`
* Including const evaluation of such casts
* Adds codegen for drop glue so things are cleaned up properly when a `dyn* Trait` object goes out of scope
* Adds codegen for method calls, at least for methods that take `&self`
Quite a bit is still missing, but this gives us a starting point. Note that this is never intended to become stable surface syntax for Rust, but rather `dyn*` is planned to be used as an implementation detail for async functions in dyn traits.
Joint work with `@nikomatsakis` and `@compiler-errors.`

Migrate write.rs to a late pass
changelog: Migrates write.rs from a pre expansion pass to a late pass
changelog: [`positional_named_format_parameters`] is renamed in favour of the rustc lint `named_arguments_used_positionally`
- Macros are now identified by diagnostic items, so will no longer lint user defined macros named, e.g. a custom `print!`
- `print_literal`/`write_literal` no longer lint no longer lint literals that come from macro expansions, e.g. `env!("FOO")`
- `print_with_newline`/`write_with_newline` no longer lint strings with any internal `\r` or `\n`s
~~A false negative, `print_literal`/`write_literal` don't lint format strings that produce `FormatSpec`s, e.g. ones containing pretty print/width/align specifiers~~
Suggestion changes:
- ~~`print_literal`/`write_literal` no longer have suggestions, as the spans for the `{}`s were not easily obtainable~~
- `print_with_newline`/`write_with_newline` has a better suggestion for a sole literal newline, but no longer has suggestions for len > 1 strings that end in a literal newline
- ~~`use_debug` spans are less precise, now point to the whole format string~~
The diff for write.rs is pretty unwieldy, other than for the `declare_clippy_lint!`s I think you'd be better off viewing it as a brand new file rather than looking at the diff, as it's mostly written from scratch

Fix `unused_peekable` closure and `f(&mut peekable)` false positives
changelog: Fix [`unused_peekable`] false positive when peeked in a closure or called as `f(&mut peekable)`
The `return`/`break` changes aren't part of the fix, they allow an earlier return in some cases. `break` is replaced with `return` for style purposes as they do the same thing in this case

[arithmetic-side-effects] More non-overflowing ops
* Adding or Subtracting 0
* Division and Module of anything other than 0
* Multiplying 1 or 0

Fix dev book
fix `implements_trait` and `in_external_macro` import path
Remove example using `match_trait_method` since its deprecated.

Use `DisplayBuffer` for socket addresses.
Continuation of https://github.com/rust-lang/rust/pull/100625 for socket addresses.
Renames `net::addr` to `net::addr::socket`, `net::ip` to `net::addr::ip` and `net::ip::display_buffer::IpDisplayBuffer` to `net::addr::display_buffer::DisplayBuffer`.
Don't panic on invalid shift while constfolding
Instead of panicking on invalid shifts while folding constants we simply give up. Fixes#9463
Notice the "attempt to shift right by `1316134912_u32`", which seems weird. AFAICS it comes from rustc itself.

Don't lint `large_stack_array` inside static items
We now check if the linted `Expr` is inside an `ItemKind::Static`, which can't take the suggested `Box<[...]`. I _think_ this is the correct fix for #9460
I removed `if_chain` while I was at it.
changelog: Don't lint `large_stack_array` inside static items
Use macro callsite when creating `Sugg` helper
Closes#9375
changelog: Improvement: [`collapsible_if`]: Suggestions now work with macros, by taking the call site into account.
[`assertions_on_result_states`]: Fix suggestion when `assert!` is not in a statement.
