Stabilize str_strip feature
This PR stabilizes these APIs:
```rust
impl str {
/// Returns a string slice with the prefix removed.
///
/// If the string starts with the pattern `prefix`, `Some` is returned with the substring where
/// the prefix is removed. Unlike `trim_start_matches`, this method removes the prefix exactly
/// once.
pub fn strip_prefix<'a, P: Pattern<'a>>(&'a self, prefix: P) -> Option<&'a str>;
/// Returns a string slice with the suffix removed.
///
/// If the string ends with the pattern `suffix`, `Some` is returned with the substring where
/// the suffix is removed. Unlike `trim_end_matches`, this method removes the suffix exactly
/// once.
pub fn strip_suffix<'a, P>(&'a self, suffix: P) -> Option<&'a str>
where
P: Pattern<'a>,
<P as Pattern<'a>>::Searcher: ReverseSearcher<'a>;
}
```

Extend useless conversion

Register redundant_field_names and non_expressive_names as early passes
Similar names was moved to a pre-expansion pass to solve #2927, so I'm avoiding linting on code from expansion, which makes the dogfood (mostly, see below) pass.
I had to change new_without_default though, and although I understand why it was not triggering before, TBH I don't see why the binding inside the nested `if_chain` is being linted now. Any ideas? (it seems legit though as the code can be changed by the user)

Make empty_line_after_outer_attr an early lint
Fixes#5567
Unfortunately I couldn't find a way to reproduce the issue without syn/quote. Considering that most real-world macros use syn and/or quote, I think it's okay to pull them in anyway.

reversed_empty_ranges: add suggestion for &slice[N..N]
As discussed in the issue thread, the user accepted this solution. Let me know if this is what we want, or if changing the way we lint the N..N case is prefered.

ptr_arg: honor `allow` attribute on arguments
The `intravisit::Visitor` impl for `LateContextAndPass` only takes into account the attributes of a function parameter inside the `check_param` method. `ptr_arg` starts its heuristics at `check_item` / `check_impl_item` / `check_trait_item`, so the `allow` is not taken into account automatically.

Add common lint tools doc
This PR starts adding some documentation about linting tools.
`Retrieving all methods of a type` is not covered at this time.
fixes partially: #3843
changelog: none
option_option test case #4298
Adds regression test case for #4298.
The bug seems still present although rust Playground said otherwise.

new_without_default: do not suggest deriving
---
changelog: do not suggest deriving `Default` in `new_without_default`
This commit changes the behavior of the `new_without_default` lint to not suggest deriving `Default`. This suggestion is misleading if the `new` implementation does something different than what a derived `Default` implementation would do, because then the two methods would not be equivalent.
Instead, the `can_derive_default` check is removed, and we always suggest implementing `Default` in terms of `new()`.
Clarify the documentation of the `unnecessary_mut_passed` lint
fixes#5433 by replacing "giving" with "passing"
changelog: Clarifies documentation for `unnecessary_mut_passed`
