Restrict `#[rustc_box]` to `Box::new` calls
Currently, `#[rustc_box]` can be applied to any call expression with a single argument. This PR only allows it to be applied to calls to `Box::new`
Update version attribute for 1.68 lints

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)

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 array-size-threshold config deserialization error

Not entirely sure why it doesn't want to deserialize a u128, but converting it after the fact is an easy enough fix

Remove `from` lang item
It was probably a leftover from the old `?` desugaring but anyways, it's unused now except for clippy, which can just use a diagnostics item.
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

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.

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.

<!-- changelog_checked -->
(This is a large commit. The changes to
`compiler/rustc_middle/src/ty/context.rs` are the most important ones.)
The current naming scheme is a mess, with a mix of `_intern_`, `intern_`
and `mk_` prefixes, with little consistency. In particular, in many
cases it's easy to use an iterator interner when a (preferable) slice
interner is available.
The guiding principles of the new naming system:
- No `_intern_` prefixes.
- The `intern_` prefix is for internal operations.
- The `mk_` prefix is for external operations.
- For cases where there is a slice interner and an iterator interner,
the former is `mk_foo` and the latter is `mk_foo_from_iter`.
Also, `slice_interners!` and `direct_interners!` can now be `pub` or
non-`pub`, which helps enforce the internal/external operations
division.
It's not perfect, but I think it's a clear improvement.

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.

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.
