The original message ("unsafe function's docs miss `# Safety` section")
reads quite awkwardly. I've changed it to "unsafe function's docs are missing
a `# Safety` section" to have it read better.

This adds a `àllow-useless-vec-in-test` configuration which, when set
to `true` will allow the `useless_vec` lint in `#[test]` functions and
code within `#[cfg(test)]`. It also moves a `is_in_test` helper to
`clippy_utils`.
[`module_name_repetition`] Recognize common prepositions
Fixes#12544
changelog: [`module_name_repetition`]: don't report an item name if it consists only of a prefix from `allowed-prefixes` list and a module name (e.g. `AsFoo` in module `foo`). Prefixes allowed by default: [`to`, `from`, `into`, `as`, `try_into`, `try_from`]
Fixes#12544.
- don't report an item name if it consists only of a prefix from `allowed-prefixes` list and a module name (e.g. `AsFoo` in module `foo`).
- configured by `allowed-prefixes` config entry
- prefixes allowed by default: [`to`, `from`, `into`, `as`, `try_into`, `try_from`]
- update docs
new lint `legacy_numeric_constants`
Rework of #10997
- uses diagnostic items
- does not lint imports of the float modules (`use std::f32`)
- does not lint usage of float constants that look like `f32::MIN`
I chose to make the float changes because the following pattern is actually pretty useful
```rust
use std::f32;
let omega = freq * 2 * f32::consts::PI;
```
and the float modules are not TBD-deprecated like the integer modules.
Closes#10995

[#12312](https://github.com/rust-lang/rust-clippy/pull/12312)
Instead of just saying “this function's stack frame is big”, report:
* the (presumed) size of the frame
* the size and type of the largest local contributing to that size
* the configurable limit that was exceeded (once)
Remove `$DIR` replacement
This won't cause problems because the old `$DIR` replacement was based on the parent of the test path, which for us is relative: 5471e0645a/tests/compile-test.rs (L122)
The new pattern being `"tests/{test_dir}"` is more clearly relative
That's why we have custom filters applied to the toml/cargo tests where absolute paths do appear in the output 5471e0645a/tests/compile-test.rs (L198-L202)
Removing it allows clicking the paths in the terminal

r? `@flip1995`
Suppress the `min_ident_chars` warning for items whose name we cannot
control. Do not warn for `use a::b`, but warn for `use a::b as c`, since
`c` is a local identifier.
Fixes#12232
Warn if an item coming from more recent version than MSRV is used

~~Currently, the lint is not working for the simple reason that the `stable` attribute is not kept in dependencies. I'll send a PR to rustc to see if they'd be okay with keeping it.~~
EDIT: There was actually a `lookup_stability` function providing this information, so all good now!
