Return with a question mark was triggered in situations where the `?` desuraging was performing error conversion via `Into`/`From`. The desugared `?` produces a match over an expression with type `std::ops::ControlFlow<B,C>` with `B:Result<Infallible, E:Error>` and `C:Result<_, E':Error>`, and the arms perform the conversion. The patch adds another check in the lint that checks that `E == E'`. If `E == E'`, then the `?` is indeed unnecessary. changelog: False Positive: `needless_return_with_question_mark` when implicit Error Conversion occurs.

There are cases where the closure call is needed in some macros, this in particular occurs when the closure has parameters. To handle this case, we allow the lint when there are no parameters in the closure, or the closure is outside a macro invocation. fixes: rust-lang#11274, rust-lang#1553 changelog: FP: [`redundant_closure_call`] when closures with parameters are passed in macros.
`unescape_literal` becomes `unescape_unicode`, and `unescape_c_string` becomes `unescape_mixed`. Because rfc3349 will mean that C string literals will no longer be the only mixed utf8 literals.

remove StructuralEq trait The documentation given for the trait is outdated: *all* function pointers implement `PartialEq` and `Eq` these days. So the `StructuralEq` trait doesn't really seem to have any reason to exist any more. One side-effect of this PR is that we allow matching on some consts that do not implement `Eq`. However, we already allowed matching on floats and consts containing floats, so this is not new, it is just allowed in more cases now. IMO it makes no sense at all to allow float matching but also sometimes require an `Eq` instance. If we want to require `Eq` we should adjust rust-lang#115893 to check for `Eq`, and rule out float matching for good. Fixes rust-lang#115881
Avoid linting redundant closure when callee is marked `#[track_caller]` Fixes rust-lang#12199 Not sure if there's a nicer way to detect functions marked `#[track_caller]` other than by just looking at its attributes 🤔 changelog: [`redundant_closure`]: [`redundant_closure_for_method_calls`]: avoid linting closures where the function being called is marked `#[track_caller]`

…lyxyas Warn if an item coming from more recent version than MSRV is used Part of rust-lang/rust-clippy#6324. ~~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! cc `@epage` changelog: create new [`incompatible_msrv`] lint
