c77fc06d52 Add lint to detect transmutes from float to integer 
Add lint that detects transmutation from a float to an integer
and suggests usage of `{f32, f64}.to_bits()` instead.

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.

5572476a36 Add lint for debug_assert_with_mut_call 
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.

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.

Deprecate unused_collect lint 
I found this because we only had two test cases in total for this lint.
It turns out the functionality is fully covered by rustc these days.

changelog: Deprecate `unused_collect` lint. This is fully covered by
rustc's `#[must_use]` on `collect`

e8dfafc7a0 readme: update 
Remove the crates.io badge from the readme.
Installing clippy via crates.io is deprecated and rustup should be used instead, thus we should not promote crates.io here.

Don't have the entire clippy::correctness line in bold letters, I think it looks a little off.

4fcaab3d62 Split redundant_closure lint 
Move the method checking into a new lint called
`redundant_closures_for_method_calls` and put it in the pedantic group.

This aspect of the lint seems more controversial than the rest.
