Fix documentation for `slow_vector_initialization`

This PR fixes the documentation for the lint `slow_vector_initialization`. The documentation recommended writing `vec![len; 0]` but the correct solution is `vec![0; len]`.

Prevent incorrect cast_lossless suggestion in const_fn 
`::from` is not a const fn, so applying the suggestion of
`cast_lossless` would fail to compile. The fix is to skip the lint if
the cast is found inside a const fn.

a40d8e4479 Auto merge of #3679 - daxpedda:use_self, r=phansch 
Fix automatic suggestion on `use_self`.

In an example like this:
```rust
impl Example {
    fn fun_1() { }
    fn fun_2() {
        Example::fun_1();
    }
}
```
Clippy tries to replace `Example::fun_1` with `Self`, loosing `::fun_1` in the process, it should rather try to replace `Example` with `Self`.

**Question**
- There may be other paths that need the same treatment, but I'm not sure I understand them fully:
  - e648adf086/clippy_lints/src/use_self.rs (L94-L96)
  - e648adf086/clippy_lints/src/use_self.rs (L225-L229)

one arguments to `format`.

Michael Wright
67a9f20c91 Fix map_clone bad suggestion 
`cloned` requires that the elements of the iterator must be references. This
change determines if that is the case by examining the type of the closure
argument and suggesting `.cloned` only if it is a reference. When the closure
argument is not a reference, it suggests removing the `map` call instead.

A minor problem with this change is that the new check sometimes overlaps
with the `clone_on_copy` lint.

Add several run rustfix annotations

Adds `run-rustfix` to 18 of the tests from the tracking issue #3630.
Each test has its own commit, to make reviewing easier (hopefully this is easier to review than 18 separate PRs).

## Changes
- `cfg_attr_rustfmt`: Custom inner attributes are unstable. Let's disable the lint for inner attributes until [#54726](https://github.com/rust-lang/rust/issues/54726) stabilizes
- `collapsible_if`: unrelated cyclomatic_complexity warning that can be ignored
- `duration_subsec`: Simply needed `#![allow(dead_code)]`
- `excessive_precision`: Fixed by `#!allow(dead_code,unused_variables)`
- `explicit_write`: Fixed by `#![allow(unused_imports)]`
- `inconsistent_digit_grouping`: Avoid triggering `clippy::excessive_precision` lint
- `infallible_destructuring_match`: Fixed by `#![allow(dead_code, unreachable_code, unused_variables)]`
- `into_iter_on_ref`: Triggered unrelated `clippy::useless_vec` lint
- `large_digit_groups`: Avoid triggering `clippy::excessive_precision` lint
- `map_clone`: Fixed by `#![allow(clippy::iter_cloned_collect)]`
- `mem_replace`: Suggestion causes import to be unused, fixed by `#![allow(unused_imports)]`
- `precedence`: Allow some unrelated lints, and change out-of-range `0b1111_1111i8` literal
- `redundant_field_names`: Allow dead code, and remove stabilized feature toggles
- `replace_consts`: Fixed by `#![allow(unused_variables)]`
- `starts_ends_with`: Fixed by `#![allow(unused_must_use)]`
- `types`: Fixed by `#![allow(dead_code, unused_variables)]`
- `unit_arg`: Fixed by `#[allow(unused_must_use)]`
- `unnecessary_fold`: Fixed by adding type annotations and adding `#![allow(dead_code)]`

5b8496603c Auto merge of #3640 - detrumi:nested_use_self, r=flip1995 
Restrict `use_self` on nested items

Fixes #3637
Fixes #3463

These changes make it so that nested items aren't visited any more by the `use_self` lint.

I think visiting nested items should be possible (so that it uses a different `item_path` for the nested item), but I'm not sure whether it's viable and what the best approach would be.
- Can `item_path` be changed to a new `Self` path before visiting the item, and then changing it back afterwards?
- Alternatively, could a new visitor be created, re-using `check_trait_method_impl_decl`?

d264e406be Auto merge of #3627 - detrumi:use_self_local_macro, r=phansch 
Trigger `use_self` lint in local macros

Closes #2098

The test currently only covers local macros. #2098 suggested this:
> You could add the macro in question into the `mini_macro` subcrate

But that doesn't work for a `macro_rules`:
```
error: cannot export macro_rules! macros from a `proc-macro` crate type currently
```

So I suggest leaving out the test for external macros, as using `in_external_macro` seems straigtforward enough. Alternatives would be to use to add an additional crate (overkill if you ask me), or test with a `proc-macro`.

Integrate rustfix into Clippy test suite

Once the [PR to compiletest-rs](https://github.com/laumann/compiletest-rs/pull/151) is reviewed and merged this fixes #2376.

I will create a separate tracking issue for adding `run-rustfix` to all tests.

~Oh, I guess this should actually check other methods like `count` as well, not only `collect()`.~
Never mind, `collect` is the only of these functions that allocates a data structure.

Fix if_same_then_else false positive

This fixes false positive in #3559.
The problem was that `SpanlessEq` does not check patterns in declarations. So this two blocks considered equal.
```rust
if true {
    let (x, y) = foo();
} else {
   let (y, x) = foo();
}
```
Not sure if the proposed change is safe as `SpanlessEq` is used extensively in other lints, but I tried hard to come up with counterexample and failed.

Fix wildcard_dependencies false positive 
This now only checks for wildcard_dependencies if the source is a

I tested this manually by modifying the main `Cargo.toml`.

Downgrade unsafe_vector_initialization to restriction 
This lint looks for:

    let mut vec = Vec::with_capacity(len);
    vec.set_len(len);

The suggested replacement is `vec![0; len]`.

This is far too opinionated to be a deny-by-default lint because the performance
characteristics of the suggested replacement are totally different.

I am not convinced that this lint has value beyond what deny(unsafe_code) gives
you. Unsafe code is unsafe but please don't deny-by-default lint it if that's
the only reason.

Downgrade needless_pass_by_value to allow by default 
I noticed that I suppress this lint in many of my projects.

https://github.com/search?q=needless_pass_by_value+user%3Adtolnay&type=Code
https://github.com/search?q=needless_pass_by_value+user%3Aserde-rs&type=Code

Upon further inspection, this lint has a *long* history of false
positives (and several remaining).

Generally I feel that this lint is the definition of pedantic and should
not be linted by default.

    #[derive(Debug)]
    enum How {
        ThisWay,
        ThatWay,
    }

    // Are we really better off forcing the call sites to write f(&_)...?
    fn f(how: How) {
        println!("You want to do it {:?}", how);
    }

        f(How::ThatWay);

RIIR update lints: Add check mode (update_lints.py rewrite complete) 
This finishes up the rewrite of `update_lints.py` in Rust. More
specifically, this

* adds the `--check` flag and handling to clippy_dev
* tracks file changes over the different calls to `replace_region_in_file`
* only writes changes to files if the `--check` flag is *not* used
* runs `./util/dev update_lints --check` on CI instead of the old script
* replaces usage of the `update_lints.py` script with an error

`./util/dev update_lints` behaves 99% the same as the python script.
The only difference that I'm aware of is an ordering change to
`clippy_lints/src/lib.rs` because underscores seem to be sorted
differently in Rust and in Python.

3353: float support added for mistyped_literal_suffixes lint r=mikerite a=Maxgy

I implemented the mistyped_literal_suffixes lint for float literals.

```
#![allow(unused_variables)]

fn main() {
    let x = 1E2_32;
    let x = 75.22_64;
}
```
Given the above, the additional check suggests the variables to be written as `let x = 1E2_f32` and `let x = 75.22_f64`.

Fixes #3167

0c1ffc1d1f Fix possible_missing_comma false positives 
`possible_missing_comma` should only trigger when the binary operator has
unary equivalent. Otherwise, it's not possible to insert a comma without
breaking compilation. The operators identified were `+`, `&`, `*` and `-`.

This fixes the specific examples given in issues #3244 and #3396
but doesn't address the conflict this lint has with the style of starting
a line with a binary operator.

3368: added downsides to "known problems" for get_unwrap lint r=flip1995 a=humean

As a beginner I found this lint to be confusing because I was not sure how the `Option` type disappeared as conceptually I know that my `.get()` and Index could fail. Initially I thought maybe the compiler or clippy was smart enough to understand that it was impossible for my `.get()` to fail in this particular case, but it was explained to me that using the Index syntax is just shorthand for directly unwrapping the value:

https://doc.rust-lang.org/src/std/collections/hash/map.rs.html#1547

For beginners or users trying to iterate quickly it seems common to litter your code with `unwrap` or `except` as placeholders for where some explicit error handling might need to take place. I think it should be warned that using Index is merely more concise, but doesn't at all reduce the risk of panics and might in fact cause you to miss handling them in a future refactor.

3217: Fix string_lit_as_bytes lint for macros r=phansch a=yaahallo

Prior to this change, string_lit_as_bytes would trigger for constructs
like `include_str!("filename").as_bytes()` and would recommend fixing it
by rewriting as `binclude_str!("filename")`.

This change updates the lint to act as an EarlyLintPass lint. It then
differentiates between string literals and macros that have bytes
yielding alternatives.

Closes #3205

This PR adds lint `redundant_clone`. It suggests to remove redundant `clone()` that clones a owned value that will be dropped without any usage after that.

3338: new_ret_no_self false positives r=flip1995 a=JoshMcguigan

~~WORK IN PROGRESS~~

I plan to fix all of the false positives in #3313 in this PR, but I wanted to open it now to start gathering feedback.

In this first commit, I've updated the lint to allow tuple return types as long as `Self` shows up at least once, in any position of the tuple. I believe this is the broadest possible interpretation of what should be allowed for tuple return types, but I would certainly be okay making the lint more strict. 

fixes #3313

4b68c965fe Resolve ICE in needless range loop lint 
An ICE would occur if the needless range loop was triggered
within a procedural macro, because Clippy would try to produce
a code suggestion which was invalid, and caused the compiler
to crash.

This commit takes the same approach which Clippy currently takes
to work around this type of crash in the needless pass by value lint,
which is to skip the lint if Clippy is inside of a macro.

9bd4e5469e Don't suggest cloned() for map Box deref 
Boxes are a bit magic in that they need to use `*` to get an owned value
out of the box. They implement `Deref` but that only returns a
reference. This means an easy way to convert an `Option<Box<T>>` to an
`<Option<T>` is:

```
box_option.map(|b| *b)
```

However, since b36bb0a6 the `map_clone` lint is detecting this as an
attempt to copy the box. Fix by excluding boxes completely from the
deref part of this lint.

Fixes #3274

fbc93c0166 Lint against needless uses of collect() 
Handles cases of `.collect().len()`, `.collect().is_empty()`, and
`.collect().contains()`. This lint is intended to be generic enough to
be added to at a later time with other similar patterns that could be
optimized.

Closes #3034

779988303a iter conservation efforts: save the endangered .iter() and .into_iter() 
Make explicit_iter_loop and explicit_into_iter_loop allow-by-default, so
that people can turn them on if they want to enforce that style; avoid
presenting them as *the* idiomatic Rust style, rather than just *a* style.

350036a0c7 default_trait_access skips <F as Default>::default() 
This includes the type name, so is clear, and may be necessary.

There doesn't seem to be an obviously cleaner way to pull out the
literal text of the named type here.

Fixes #2879

cc87dc7539 Move some range lints to complexity 
Recategorize `range_plus_one` and `range_minus_one` to `complexity`.
This moves `range_plus_one` out of the nursery as the inclusive range
syntax is now stable. Both are moved to `complexity` as it is more
consistent with other lints such as `int_plus_one`.
