Move [`assertions_on_result_states`] to restriction
Close #9263
This lint causes regression on readability of code and log output. And printing runtime values is not particularly useful for majority of tests which should be reproducible.
changelog: Move [`assertions_on_result_states`] to restriction and don't lint it for unit type

Remove "blacklist" terminology
Picking up where https://github.com/rust-lang/rust-clippy/pull/5896 left off, this renames the `blacklisted_name` lint to `disallowed_names` (pluralised for compliance with naming conventions). The old name is still available though is deprecated (both in the lint name, and in the TOML configuration file).
This has been proposed/requested a few times, most recently in https://github.com/rust-lang/rust-clippy/issues/7582 where `@xFrednet` suggested pinging the Clippy team when a PR was created hence...
Auto merge of #9252 - Metaswitch:use-deprecated-config, r=Jarcho
Read and use deprecated configuration (as well as emitting a warning)
Original change written by `@flip1995` I've simply rebased to master and fixed up the formatting/tests. This change teaches the configuration parser which config key replaced a deprecated key and attempts to populate the latter from the former. If both keys are provided this fails with a duplicate key error (rather than attempting to guess which the user intended).
Currently this on affects `cyclomatic-complexity-threshold` -> `cognitive-complexity-threshold` but will also be used in #8974 to handle `blacklisted-names` -> `disallowed-names`.
```
changelog: deprecated configuration keys are still applied as if they were provided as their non-deprecated name.

lint: add bad opt access internal lint
Some command-line options accessible through `sess.opts` are best
accessed through wrapper functions on `Session`, `TyCtxt` or otherwise,
rather than through field access on the option struct in the `Session`.
Adds a new lint which triggers on those options that should be accessed
through a wrapper function so that this is prohibited. Options are
annotated with a new attribute `rustc_lint_opt_deny_field_access` which
can specify the error message (i.e. "use this other function instead")
to be emitted.
A simpler alternative would be to simply rename the options in the
option type so that it is clear they should not be used, however this
doesn't prevent uses, just discourages them. Another alternative would
be to make the option fields private, and adding accessor functions on
the option types, however the wrapper functions sometimes rely on
additional state from `Session` or `TyCtxt` which wouldn't be available
in an function on the option type, so the accessor would simply make the
field available and its use would be discouraged too.
Auto merge of #97313 - cjgillot:ast-lifetimes-anon, r=petrochenkov
Resolve function lifetime elision on the AST
~Based on https://github.com/rust-lang/rust/pull/97720~
Lifetime elision for functions is purely syntactic in nature, so can be resolved on the AST.
This PR replicates the elision logic and diagnostics on the AST, and replaces HIR-based resolution by a `delay_span_bug`.
This refactor allows for more consistent diagnostics, which don't have to guess the original code from HIR.

Fix `useless_format` spans for `format!("{foo}")`
Fixes #9234
changelog: [`useless_format`]: Fix spans for `format!("{foo}")`
https://github.com/rust-lang/rust/pull/94030 made our workaround unneeded, but by coincidence our test still passed [because `Span::new()` swaps `hi` & `lo` if needed](https://github.com/rust-lang/rust/blob/c32dcbba187d1ee0dbe92dc152cb9c2f3f42900c/compiler/rustc_span/src/span_encoding.rs#L86-L88). So with a single character variable like `format!("{x}")` it still worked
Auto merge of #9214 - Jarcho:assign_op_prim, r=Manishearth
Check `assign_op_pattern` for conflicting borrows
fixes #9180
changelog: [`assign_op_pattern`](https://rust-lang.github.io/rust-clippy/master/#assign_op_pattern): Don't lint when the suggestion would cause borrowck errors.
This PR adds a test to check the metadata of packages in the `ui_cargo` directory.
A recent change to Cargo causes it to warn when it finds multiple packages with the same name in a git dependency (the issue is described [here](https://github.com/rust-lang/cargo/issues/10752)).
Many (if not all) Dylint libraries depend upon `clippy_utils`. As a result of the change, one now sees the following when building a Dylint library:
```

```
There appear to be two contributing factors:
- Some packages in `ui_cargo` could have a `publish = false` added to them.
- Some packages in `ui_cargo` seem to be inconsistently named.
The new test checks that each package in the `ui_cargo` directory has a name matching one of its parent directories, and `publish = false` in its metadata (with a few exceptions).
Note that the packages in `cargo_common_metadata` require special care because `publish` is the subject of some of the `cargo_common_metadata` tests.
Also note that this PR adds `walkdir` as a dev dependency to the `clippy` package. However, it was already a dependency of `clippy_dev` and `lintcheck`. So hopefully this is acceptable.
Our continued thanks for making `clippy_utils` available, BTW. :)

Update highlight.js
changelog: none
With [highlight.js v11.6.0](https://github.com/highlightjs/highlight.js/releases/tag/11.6.0), the lint list can finally update from `9.5.0`. No more EOL warning in console! :smile:
I also made it switch to the `github-dark` theme when using `coal`, instead of just always using the normal github light theme.
