Downgrade option_if_let_else to nursery
I believe that this lint's loose understanding of ownership (#5822, #6737) makes it unsuitable to be enabled by default in its current state, even as a pedantic lint.
Additionally the lint has known problems with type inference (#6137), though I may be willing to consider this a non-blocker in isolation if it weren't for the ownership false positives.
A fourth false positive involving const fn: #7567.
But on top of these, for me the biggest issue is I basically fully agree with https://github.com/rust-lang/rust-clippy/issues/6137#issuecomment-705605688. In my experience this lint universally makes code worse even when the resulting code does compile.

Use `avoid-breaking-exported-api` configuration in types module
This PR empowers our lovely `avoid-breaking-exported-api` configuration value to also influence the emission of lints inside the `types` module.
(That's pretty much it, not really a change worthy of writing a fairy tale about. Don't get me wrong, I would love to write a short one, but I sadly need to study now).

Closes: rust-lang/rust-clippy#7489
changelog: The `avoid-breaking-exported-api` configuration now also works for [`box_vec`], [`redundant_allocation`], [`rc_buffer`], [`vec_box`], [`option_option`], [`linkedlist`], [`rc_mutex`]
changelog: [`rc_mutex`]: update the lint message to comply with the normal format

r? `@camsteffen,` as you implemented the configuration value
cc: `@flip1995,` as we've discussed this change in rust-lang/rust-clippy#7308
Add `unwrap_or_else_default` lint
---
*Please write a short comment explaining your change (or "none" for internal only changes)*
changelog: Add a new [`unwrap_or_else_default`] style lint. This will catch `unwrap_or_else(Default::default)` on Result and Option and suggest `unwrap_or_default()` instead.
No effect inclusive range
I noticed during last PR that range expression is `ExprKind::Struct` while inclusive range is `ExprKind::Call` which was why it was not handled. This PR adds check for this case.
changelog: [`no_effect]` Report inclusive range in no_effect lint
`never_loop`: suggest using an `if let` instead of a `for` loop
changelog: suggest using an `if let` statement instead of a `for` loop that [`never_loop`]s
Fixes#7537, r? `@camsteffen.`
Clean up examples in new lint suggestion template
I'm pretty sure they meant to write `bounds checking` when they wrote `bounce checking` but I could be wrong. After that I thought I could improve it further and ended up with this.
changelog: none
Cleanup usage of `span_to_snippet` and `LintContext::sess`
- avoid using `SourceMap::span_to_snippet` directly and use `clippy_utils::source::snippet_opt` instead
- don't use `LintContext::sess()` on `EarlyContext`s which have a `sess` field directly available, saving the import of `LintContext`
changelog: none
Don't emit `too_many_lines` for closures
changelog: don't emit the [`too_many_lines`] lint inside closures to avoir duplicated diagnostics.
Fixes#7517.
fix bug on mutable ref
fixes: #7524
This PR is related to issue #7524
changelog: [`extend_with_drain`] Improve code suggestion for mutable and immutable references
rustc: Replace `HirId`s with `LocalDefId`s in `AccessLevels` tables
and passes using those tables - primarily privacy checking, stability checking and dead code checking.
All these passes work with definitions rather than with arbitrary HIR nodes.
