restriction lint for `std::process::exit`
Addition to #4655 - adds the lint checking for `std::process::exit`
changelog: add restriction lint for `std::process::exit`
Fix Deprecated lints don't expand
### Move doc comments inside of declare_deprecated_lint macros so that they are picked up by lintlib.py
### fixes#4748
Unable to `cargo test` locally (I'm on NixOS, and keep getting errors that are similar to those #4714 might solve) but I have verified that all deprecated lints can now be expanded like other lints.
changelog: Show deprecated lints in lint documentation again
Specifically, this revises the clippy integration to utilize a new
callback to register its lints, as the prior editing of lint store in
Session is no longer possible.
Add lint for debug_assert_with_mut_call
closes#1526
**What does not work:**
* detecting a mut call in the format string itself, e.g. `debug_assert!(false, "{}", vec![1].pop())`
* detecting `*mut T` usage (pointer)
---
changelog: add new lint `debug_assert_with_mut_call`
Fix suggestion of `explicit_counter_loop`
changelog: In the suggestion of `explicit_counter_loop`, if the `for` loop argument doesn't implement `Iterator`, then we suggest `x.into_iter().enumerate()` (or `x.iter{_mut}()` as appropriate). Also, the span of the suggestion has been corrected.
Fixes#4678
This lint will complain when you put a mutable function/method call
inside a `debug_assert` macro, because it will not be executed in
release mode, therefore it will change the execution flow, which is not
wanted.
Add `inefficient_to_string` lint
Closes#4586
changelog: Add `inefficient_to_string` lint, which checks for calling `to_string` on `&&str`, which would bypass the `str`'s specialization
`must_use_unit` lints unit-returning functions with a `#[must_use]`
attribute, suggesting to remove it.
`double_must_use` lints functions with a plain `#[must_use]`
attribute, but which return a type which is already `#[must_use]`,
so the attribute has no benefit.
`must_use_candidate` is a pedantic lint that lints functions and
methods that return some non-unit type that is not already
`#[must_use]` and suggests to add the annotation.
Lints when, on the RHS of a BinOp, there is a UnOp without a space
before the operator but with a space after (e.g. foo >- 1).

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.
- [x] Followed [lint naming conventions][lint_naming]
- [x] Added passing UI tests (including committed `.stderr` file)
- [ ] `cargo test` passes locally
- [x] Executed `./util/dev update_lints`
- [ ] Added lint documentation
- [ ] Run `./util/dev fmt`

- [x] suggest replacing `assert!(false, "msg")` with `panic!("msg")`

Work towards fixing: #3575
Fix typo in inherent_to_string documentation
A simple typo fix in `inherent_to_string` and `inherent_to_string_shadow_display` documentation
changelog: none
account for doc visibility
This fixes#4608.
Also I noticed that the lint failed to look at trait and impl items. There's a small bit of fallout in the code, too, but not enough to warrant its own commit.
changelog: check docs of trait items and impl items, also make `missing_safety_doc` account for visibility
Add check for assert_eq macros to unit_cmp lint
changelog: Add check for unit comparisons through `assert_eq!`, `debug_assert_eq!`, `assert_ne!` and `debug_assert_ne!` macros to unit_cmp lint.

Fix false positive in `multiple_inherent_impl`
changelog: Fix false positive in `multiple_inherent_impl` by ignoring impls derived from macros.
Closes#4578.
Add a new lint for comparison chains
changelog: Adds a new lint: `comparison_chain`.
`comparison_chain` lints all `if` conditional chains where all the conditions are binary comparisons on the same two operands and will suggest a rewrite with `match`.
Closes#4531.
When license property is missing in Cargo.toml check for license-file
as it may be used instead of the former. The check implemented here is
very naive as it only verifies that the field is present and is not
empty. More scrutiny can be applied by verifying the file is actually
present.
Fixes#4517
