Suggest .copied() for map_clone on iterators too
fixes https://github.com/rust-lang/rust-clippy/issues/3958
changelog: Make `map_clone` suggest the newly-stable `Iterator::copied()` when applicable

Do not trigger redundant_closure for non-function types
fixes#3898
Added a check for the entity being called in the closure body to be a FnDef. This way lint does not trigger for ADTs (Box) but I'm not sure if it's correct and not too restrictive.

Thank you for making Clippy better!
We're collecting our changelog from pull request descriptions.
If your PR only updates to the latest nightly, you can leave the
`changelog` entry as `none`. Otherwise, please write a short comment
explaining your change.
If your PR fixes an issue, you can add "fixes #issue_number" into this
PR description. This way the issue will be automatically closed when
your PR is merged.
If you added a new lint, here's a checklist for things that will be
checked during review or continuous integration.
- [ ] Followed [lint naming conventions][lint_naming]
- [ ] Added passing UI tests (including committed `.stderr` file)
- [ ] `cargo test` passes locally
- [ ] Executed `util/dev update_lints`
- [ ] Added lint documentation
- [ ] Run `cargo fmt`
Note that you can skip the above if you are just opening a WIP PR in
order to get feedback.

changelog: Fix false positive in `redundant_closure` pertaining to non-function types
Ignore non-const ctor expressions in or_fn_call
Fixes https://github.com/rust-lang/rust-clippy/issues/1338
Should have been fixed by #919, however that focuses on const ctor expressions only, and `.or(Some(local))` isn't const.
This also automatically ignores things like `.or(Some(local.clone())` which we don't actually want to do; I need to figure out what to do here.

Allow allowing of toplevel_ref_arg lint
I'm not sure why some lints need the `HirId` to be able to recognize the
lint level attributes, but this commit makes the lint level attributes
work for `toplevel_ref_arg`.
Fixes#2332

Fix false positive in module_name_repetitions lint
This lint was triggering on modules inside expanded attrs, like
for example `#[cfg(test)]` and possibly more.
It was not reporting a location in #3892 because `span.lo()` and `span.hi()` both were 0.

Change naive_bytecount applicability to MaybeIncorrect
We can't use `MachineApplicable` here as applying the fix will cause
another error because `bytecount` would first have to be added to the
Cargo.toml.
Example:
```
error: You appear to be counting bytes the naive way
--> $DIR/bytecount.rs:5:13
|
LL | let _ = x.iter().filter(|&&a| a == 0).count(); // naive byte count
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: Consider using the bytecount crate: `bytecount::count(x, 0)`
```
Just replacing it with the suggestion is not enough.
cc #3630
Change while_let_loop applicability to HasPlaceholders
The suggestion has been changed at some point to use `..` in the suggested code.
Due to that we can't make the lint MachineApplicable anymore.
cc #3630
This was causing two different ICEs in #3741.
The first was fixed in #3925.
The second one is fixed with this commit: We just don't `expect`
anymore. If the snippet doesn't contain an `else`, we stop emitting the
lint because it's not a suspiciously formatted else anyway.
Fix ICE in decimal_literal_representation lint
Handling the integer parsing properly instead of just unwrapping.
Note that the test is not catching the ICE because plain UI tests
[currently hide ICEs][compiletest_issue]. Once that issue is fixed, this
test would fail properly again.

Fix `explicit_counter_loop` suggestion
#1670
This code seems to me to work, but I have two question.
* Because range expression desugared in hir, `Sugg::hir` doesn't add parenthesis to range expression. Which function is better to check range do you think, `check_for_loop_explicit_counter` or `hir_from_snippet`?
* Do you think we need to distinguish between range expression and struct expression that creates `std::ops::Range*`?
* Late Lint pass, catches:
* One liner: 0 -> null -> transmute
* One liner: std:null() -> transmute
* Const (which resolves to null) -> transmute
* UI Test case for Lint
* Updated test for issue 3849, because now the lint that code generated is in Clippy.
* Expanded `const.rs` miri-based Constant Folding code, to cover
raw pointers
Add `doc(include = ...)` detection to `missing_docs_in_private_items`
The whole `missing documentation in crate` part doesn't have any tests. If I should add test cases tell me.
Fix `boxed_local` suggestion
Don't warn about an argument that is moved into a closure.
ExprUseVisitor doesn't walk into nested bodies so use a new
visitor that collects the variables that are moved into closures.
Fixes#3739
Refactor: Cleanup one part of assign_ops lint
Removes a lot of indentation and separates lint emission from lint
logic. Only touches the `hir::ExprKind::AssignOp` part of the lint.
Refactor: Extract `trait_ref_of_method` function
This pattern was used in three places after #3844, so I think it's worth moving it into `utils/mod.rs` and documenting it.
