Update version attribute for 1.68 lints
Roses are red,
violets are blue,
I'm running out of rhymes,
changelogs are crimes????

Two small documentation improvements
The `wrong_self_convention` changes are for grammar and accuracy.
The `must_use_candidate` change is because that lint flags only exported functions: 8b65632b6e/clippy_lints/src/functions/must_use.rs (L27-L31)
changelog: `wrong_self_convention` and `must_use_candidate` documentation improvements
Scope `missing_docs_in_private_items` to only private items
`missing_docs_in_private_items` currently detects missing docs for public items as well as private. Since `missing_docs`already covers public items, this PR updates `missing_docs_in_private_items` to only cover private items.
Fixes#1895
changelog: [`missing_docs_in_private_items`]: Apply lint only to private items (used to be public and private)
Run dogfood to completion
Run dogfood on all packages before failing the test. Failing early is painful on lints which trigger on multiple crates.

Fix ICE in `multiple_unsafe_ops_per_block`
fixes#10367
changelog: [`multiple_unsafe_ops_per_block`]: Fix ICE when calling a function-like object in an unsafe block
Fix array-size-threshold config deserialization error
changelog: Fix error when providing an `array-size-threshold` in `clippy.toml`
Not entirely sure why it doesn't want to deserialize a u128, but converting it after the fact is an easy enough fix
Fixes#10422
Do not suggest to derive `Default` on generics with implicit arguments
Fixes#10396
changelog: FP: [`derivable_impls`]: do not suggest to derive `Default` on generics with implicit arguments
chore: remove unneeded rustfmt skip
---
The associated rustfmt bug that originally necessitated these skips was resolved a while back, so these are no longer necessary
changelog: none
Do not panic when analyzing the malformed origin of a format string
Fixes#10148. This will trigger only when generating format strings while accepting weird things in a procedural macro and setting the span to something which is not a string.
changelog: none
Fix test function checker in `unwrap_used`, `expect_used`
After #9686 , `unwrap` and `expect` in integration tests and raw test functions won't be allowed.

Add new lint no_mangle_with_rust_abi
Fixes issue #10347
This PR adds a new lint `no_mangle_with_rust_abi` that suggests converting a function to the C ABI to if the function has the `#[no_mangle]` attribute and `Abi == Abi::Rust`. It will not run for any of the other variants defined in [rustc_target::spec::abi::Abi](https://doc.rust-lang.org/beta/nightly-rustc/rustc_target/spec/abi/enum.Abi.html), nor suggest any conversion other than conversion to the C ABI.
Functions that explicitly opt into the Rust ABI with `extern "Rust"` are ignored by this lint.

changelog: [`no_mangle_with_rust_abi`]: add lint that converts Rust ABI functions with the `#[no_mangle]` attribute to C ABI
Fix more false positives for `extra_unused_type_parameters`
Builds on #10321. All empty functions are no longer linted, instead of just those that have trait bounds on them. Also, if a trait bound contains a non-public trait (un-exported, but still potentially reachable), then the corresponding type parameter isn't linted.
Finally, added support for the `avoid_breaking_exported_api` config option.

Remove type-traversal trait aliases
#107924 moved the type traversal (folding and visiting) traits into the type library, but created trait aliases in `rustc_middle` to minimise both the API churn for trait consumers and the arising boilerplate. As mentioned in that PR, an alternative approach of defining subtraits with blanket implementations of the respective supertraits was also considered at that time but was ruled out as not adding much value.
Unfortunately, it has since emerged that rust-analyzer has difficulty with these trait aliases at present, resulting in a degraded contributor experience (see the recent [r-a has become useless](https://rust-lang.zulipchat.com/#narrow/stream/182449-t-compiler.2Fhelp/topic/r-a.20has.20become.20useless) topic on the #t-compiler/help Zulip stream).
This PR removes the trait aliases, and accordingly the underlying type library traits are now used directly; they are parameterised by `TyCtxt<'tcx>` rather than just the `'tcx` lifetime, and imports have been updated to reflect the fact that the trait aliases' explicitly named traits are no longer automatically brought into scope. These changes also roll-back the (no-longer required) workarounds to #107747 that were made in b409329c62.
Since this PR is just a find+replace together with the changes necessary for compilation & tidy to pass, it's currently just one mega-commit. Let me know if you'd like it broken up.

Update readme description of `restriction` lints to dissuade casual use.
Adds some stronger wording about not enabling `restriction` lints. I've seen it come up a few times where people are confused about what the `restriction` category is for and end up casually enabling lints from it (or the whole category).

Extend `CodegenBackend` trait with a function returning the translation
resources from the codegen backend, which can be added to the complete
list of resources provided to the emitter.
Signed-off-by: David Wood <david.wood@huawei.com>
Instead of loading the Fluent resources for every crate in
`rustc_error_messages`, each crate generates typed identifiers for its
own diagnostics and creates a static which are pulled together in the
`rustc_driver` crate and provided to the diagnostic emitter.

Normalize projections types when checking `explicit_auto_deref`
fixes#10384
