4972989b61 Add a lint for an async block/closure that yields a type that is itself awaitable. 
This catches bugs of the form

tokio::spawn(async move {
    let f = some_async_thing();
    f // Oh no I forgot to await f so that work will never complete.
});

4f4abf4e06 Warn about explicit self-assignment 
Warn about assignments where left-hand side place expression is the same
as right-hand side value expression. For example, warn about assignment in:

```rust
pub struct Event {
    id: usize,
    x: i32,
    y: i32,
}

pub fn copy_position(a: &mut Event, b: &Event) {
    a.x = b.x;
    a.y = a.y;
}

126790999a new lint: Returning unit from closures expecting Ord 
This lint catches cases where the last statement of a closure expecting
an instance of Ord has a trailing semi-colon. It compiles since the
closure ends up return () which also implements Ord but causes
unexpected results in cases such as sort_by_key.

Fixes #5080

New lint: iter_next_slice

Hello, this is a work-in-progress PR for issue: https://github.com/rust-lang/rust-clippy/issues/5572

I have implemented lint to replace `iter().next()` for `slice[index..]` and `array` with `get(index)` and `get(0)` respectively. However since I made a lot of changes, I would like to request some feedback before continuing so that I could fix mistakes.

Thank you!

RwLockReadGuard, or RwLockWriteGuard. If we find one then we emit a lint.

Rollup merge of #5248 - ThibsG:ConstValues, r=flip1995 
Add lint on large non scalar const

This PR adds the new lint `non_scalar_const` that aims to warn against `const` declaration of large arrays. For performance, because of inlining, large arrays should be preferably declared as `static`.

Note: i made this one to warn on all const arrays, whether they are in a body function or not. I don't know if this is really necessary, i could just reduce this lint to variables out of function scope.

Fixes: #400

f5d0a452ba Add lint for pub fns returning a Result without documenting errors 
The Rust Book recommends that functions that return a `Result` type have
a doc comment with an `# Errors` section describing the kind of errors
that can be returned
(https://doc.rust-lang.org/book/ch14-02-publishing-to-crates-io.html#commonly-used-sections).
This change adds a lint to enforce this. The lint is allow by default;
it can be enabled with `#![warn(clippy::missing_errors_doc)]`.

Closes #4854.

cc622608db new lints around #[must_use] fns 
`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.

changelog: Allow tool lints (`clippy::*`) to be deprecated

`register_removed` was registering lints to be removed _without_ the

5f3c340bfb Lint for trait methods without bodies 
As discussed in rust-lang/rust#47475 the #[inline] attribute is
currently allowed on trait methods without bodies (i.e. without a
default implementation). This is misleading as it could be interpreted
as affecting the implementations of the trait method. Add a lint for any
use of #[inline] on a trait method without a body.

Fixes rust-lang/rust#47475
