Add more license annotations
This PR updates the `.reuse/dep5` file to include more accurate licensing data for everything in the repository (*excluding* submodules and dependencies). Some decisions were made in this PR:
* The standard copyright attribution for files maintained by us is "The Rust Project Developers (see https://thanks.rust-lang.org)", to avoid having to maintain an in-tree `AUTHORS` file.
* For files that have specific licensing terms, we added the terms to the `.reuse/dep5` rather than adding SPDX comments in the files themselves.
* REUSE picks up any comment/text line with `Copyright` on it, so I had to sprinkle around `REUSE-IgnoreStart` and `REUSE-IgnoreEnd` comments.
The rendered `COPYRIGHT` file is available at https://gist.github.com/pietroalbini/efb81103f69596d39758114f3f6a8688.

Don't lint `manual_clamp` in const contexts.
fixes#10474
Probably worth including in the sync.

Migrate `write.rs` to `rustc_ast::FormatArgs`
changelog: none
Part 1 of #10233
The additions to `clippy_utils` are the main novelty of this PR, there's no removals yet since other parts still rely on `FormatArgsExpn`
The changes to `write.rs` itself are relatively straightforward this time around, as there's no lints in it that rely on type checking format params

Mark Rust 1.68.0 as release in the changelog
Roses are red,
this poem is dead,
my creativity is lost,
outside there is frost?
Maybe I should really stop including a "roses are red" with every changelog PR. These are getting worse every time...

Include async functions in the len_without_is_empty
fixes#7232
Changes done to the functionality:
Allowing different error types for the functions was disallowed. So the following was linted before but is not after this change
```
impl Foo {
pub len(&self) -> Result<usize, Error1> { todo!(); }
pub is_empty(&self) -> Result<bool, Error2> { todo!(); }
}
```

[arithmetic_side_effects] Fix#10252Fix#10252
At least for integers, shifts are already handled by the compiler.

changelog: [`arithmetic_side_effects`]: No longer lints on right or left shifts with constant integers, as the compiler warns about them.

This was previously needed because the indirection used to hide some unexplained lifetime errors, which it turned out were related to the `min_choice` algorithm.
Removing the indirection also solves a couple of cycle errors, large moves and makes async blocks support the `#[track_caller]` annotation.
Add the `popular-crates` binary
This program downloads crates info from <https://crates.io/> and builds a TOML file that can be fed to `lintcheck`.
I have been asked, on various pull requests, what the result of `lintcheck` was. However, the default configuration file for lintcheck is limited. This `popular-crates` program allows building a recent list of the recently most downloaded crates from <https://crates.io> and feed it to `lintcheck`. Using it, it was easy to test two new lints against the 500 recently most downloaded crates to ensure that there was no regression.

Do not implement HashStable for HashSet (MCP 533)
This PR removes all occurrences of `HashSet` in query results, replacing it either with `FxIndexSet` or with `UnordSet`, and then removes the `HashStable` implementation of `HashSet`. This is part of implementing [MCP 533](https://github.com/rust-lang/compiler-team/issues/533), that is, removing the `HashStable` implementations of all collection types with unstable iteration order.
The changes are mostly mechanical. The only place where additional sorting is happening is in Miri's override implementation of the `exported_symbols` query.
Add `collection_is_never_read`
Fixes#9267
`@flip1995` and `@llogiq,` I talked with you about this one at Rust Nation in London last week. :-)
This is my first contribution to Clippy, so lots of feedback would be greatly appreciated.
- \[ ] Followed [lint naming conventions][lint_naming]
- \[x] Added passing UI tests (including committed `.stderr` file)
- \[x] `cargo test` passes locally
- \[x] Executed `cargo dev update_lints`
- \[x] Added lint documentation
- \[x] Run `cargo dev fmt`
`dogfood` found one true positive (see #9509) and no false positives.
`lintcheck` found no (true or false) positives, even when running on an extended set of crates.
