4c881d108a clippy::cargo_common_metadata: check for license-file
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.

#4542 remove machine applicable suggestion

This helps #4542 (but does not completely resolve) by removing the machine applicable suggestion (which was incorrect) for that case.

I would have preferred to fix the machine applicable suggestion to handle format strings, but that's a bit beyond my current understanding of the clippy codebase. I'd be happy to give it a try given some guidance.

Changes cast-lossless to a pedantic lint

As discussed in #4528, this moves the cast-lossless lint from `all` to `pedantic`.

I couldn't tell from description alone if it should also be removed from the complexity category, so I left it as part of complexity for now. I didn't see any impact to the tests from this change, but I could be wrong (as this is my first PR).

fixes #4528

changelog: Moves cast-lossless from default to checking only as a `pedantic` lint.

Allow block_in_if_{stmt,expr} in external macro

I found this by running `cargo fix --clippy` on quite a big codebase.

You could refactor this assert to
```rust
let block_expr = _;
assert!(block_expr);
```

but,
1. it doesn't increase the readability IMO
2. That isn't possible in a `debug_assert!`

I'm not sure though, if we should allow this for macros in general or just for external macros.

changelog: none

This removes the `Vec<Symbol>` allocation. We still need to call `cx.get_def_path`, but this should already have been interned, and I don't see how we can keep ergonomics of that function without allocating a `Vec`.

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 `./util/dev fmt`

Fixes the problem displayed in https://github.com/rust-lang/rust-clippy/issues/4344#issuecomment-519206388.

We now append `{}` to the suggestion so that the conditional has the
correct syntax again.

(If we were to _remove_ the `if` instead, it would trigger the
`unused_must_use` warning for `#[must_use]` types.)

Add autofixable suggestion for unseparated integer literal suffixes

changelog: Add autofixable suggestion for unseparated integer literal suffixes

Somewhat WIP, since I haven't been able to get this working when adding `// run-rustfix` to `ui/literals.rs`. I think the issue is that there are multiple suggestions operating on one numerical literal, and I'm not sure what the best approach is to work around that.

new_ret_no_self: allow Self in inner type for impl Trait return types

Check the inner types of associated types of a trait when checking for Self in the return type of a `new` method. This means that the following will no longer warn:
```rust
trait Trait {
    type Inner;
}

struct S;

impl S {
    fn new() -> impl Trait<Inner = Option<Self>> {
        struct TraitImpl;

        impl Trait for TraitImpl {
            type Inner = Option<S>;
        }

        TraitImpl
    }
}
```
```rust
#![feature(async_await)]

struct Connection;

impl Connection {
    async fn new() -> Result<Self, ()> {
        Ok(S)
    }
}
```
closes #4359

Don't emit enum_variant_names if remainder starts with a numeric

changelog: Fix false positive in `pub_enum_variant_names` and `enum_variant_names`

As [per the reference](https://doc.rust-lang.org/reference/identifiers.html), identifiers must start with a letter. So we don't suggest a better
variant naming in case the remainder would start with a numeric.

Fixes #739

trait bounds lint - repeated types

This PR is to tackle https://github.com/rust-lang/rust-clippy/issues/3764 it's still a WIP and doesn't work but this is an initial stab. It builds though I haven't added any tests as I'm not sure where lint tests should go?

Unfortunately, it seems id isn't tied to the type itself but I guess where it is in the AST? Looking at https://manishearth.github.io/rust-internals-docs/syntax/ast/struct.Ty.html I can't see any members that would let me tell if a type was repeated in multiple trait bounds.

There may be other issues with how I've implemented this so any assistance is appreciated!

This lint adds warning if types are redundantly repeated in trait bounds i.e. `T: Copy, T: Clone` instead of `T: Copy + Clone`. This is a late pass trait lint and has necessitated the addition of code to allow hashing of TyKinds without taking into account Span information.

fixes #3988

changelog: Ignore generated fresh lifetimes in elision check.

**HELP**: It seems `tests/ui` are compiled under edition 2015, and I don't know how to add tests for this properly.

Here is the test input it had already passed:
```rust
#![feature(async_await)]
#![allow(dead_code)]

async fn sink1<'a>(_: &'a str) {} // lint
async fn sink1_elided(_: &str) {} // ok

async fn one_to_one<'a>(s: &'a str) -> &'a str { s } // lint
async fn one_to_one_elided(s: &str) -> &str { s } // ok
async fn all_to_one<'a>(a: &'a str, _b: &'a str) -> &'a str { a } // ok
// async fn unrelated(_: &str, _: &str) {} // Not allowed in async fn

// #3988
struct Foo;
impl Foo {
    pub async fn foo(&mut self) {} // ok
}

// rust-lang/rust#61115
async fn print(s: &str) { // ok
    println!("{}", s);
}
