Extend `maybe_misused_cfg` lint over `cfg(test)`
Fixes#11240.
One thought I had is that we could use the levenshtein distance (of 1) to ensure this is indeed `test` that was targeted. But maybe it's overkill, not sure.

r? `@blyxyas`
This was made possible by the removal of plugin support, which
simplified lint store creation.
This simplifies the places in rustc and rustdoc that call
`describe_lints`, which are early on. The lint store is now built before
those places, so they don't have to create their own lint store for
temporary use, they can just use the main one.

Change `if_same_then_else` to be a `style` lint

disallow calls to `LintContext::struct_span_lint` and `TyCtxt::struct_span_lint_hir`
`LintContext::struct_span_lint` and `TyCtxt::struct_span_lint_hir` don't show the link to the clippy documentation, see: #11805
In #11810, the last few calls to those methods were replaced with `span_lint_*`. It seems like we should just disallow them altogether so that no new code tries to use them.
The existing `disallowed_methods` lint makes this easy.

[`impl_trait_in_params`]: avoid ICE when function with `impl Trait` type has no parameters
Fixes#11803
If I'm reading the old code correctly, it was taking the span of the first parameter (without checking that it exists, which caused the ICE) and uses that to figure out where the generic parameter to insert should go (cc `@blyxyas` you wrote the lint, is that correct?).
This seemed equivalent to just `generics.span`, which doesn't require calculating the spans like that and simplifies it a fair bit
changelog: don't ICE when function has no parameters but generics have an `impl Trait` type
add help text where missing to lints
Fixes https://github.com/rust-lang/rust-clippy/issues/11805
Essentially just changes the section of code that applies the lint from using `cx.struct_span_lint` and instead opts for `span_lint_and_then`, which automatically appends the help text.
changelog: add missing help text for `cast_possible_wrap`, `mod_module_files`, and `self_named_module_files` lints

Implement new lint `iter_over_hash_type`
Implements and fixes https://github.com/rust-lang/rust-clippy/issues/11788
This PR adds a new *restriction* lint `iter_over_hash_type` which prevents `Hash`-types (that is, `HashSet` and `HashMap`) from being used as the iterator in `for` loops.
The justification for this is because in `Hash`-based types, the ordering of items is not guaranteed and may vary between executions of the same program on the same hardware. In addition, it reduces readability due to the unclear iteration order.
The implementation of this lint also ensures the following:
- Calls to `HashMap::keys`, `HashMap::values`, and `HashSet::iter` are also denied when used in `for` loops,
- When this expression is used in procedural macros, it is not linted/denied.
changelog: add new `iter_over_hash_type` lint to prevent unordered iterations through hashed data structures
fix: [manual_memcpy] reduce indexing suggestions when array length is equal to loop range
fixes: #11689
This PR improves `manual_memcpy` suggestions by reducing unnecessary indexing.
For example,
```rust
let src = [0, 1, 2, 3, 4];
let mut dest = [0; 4];
for i in 0..4 {
dest[i] = src[i];
{
```
Clippy suggests `dest[..4].copy_from_slice(&src[..4]);`.
I reduced this suggestion as `dest.copy_from_slice(&src[..4]);`. (Removed needless indexing.)

Removing @Centri3 from reviewer rotation
Catherine decided that the best course of action would be to (maybe temporarily) remove her from the reviewer's rotation (but not unassign her from her current reviews). This PR does that. She'll always be welcomed back if she wants to review some more ❤️

>Catherine, Fred (`@xFrednet` ) noticed that you aren't as active as in the summer, and proposed that maybe you preferred to be removed from the reviewer rotation. Don't worry, you aren't being taken out of the team, just wanted to know if you maybe preferred to not have those reviews pilling up (they can be pretty stressful to see).

>If you decide to step out of the reviewers rotation, you wouldn't be removed from the team, you just wouldn't have that responsability. Everyone takes break and that's fine, so yeah, if you want to not have to review PRs, let me know!

>So yeah, from weird teenager transfem to (probably weird) teenager transfem, the choice is in your hand.

>Catherine (Centri3): Yeah that's probably best now, I'll still try with any I'm currently assigned to but I would prefer not to get anymore until then
