### Change
Adding a new lint that will emit a warning when using "unwrap" or "expect" inside a function that returns result.
### Motivation
These functions promote recoverable errors to non-recoverable errors which may be undesirable in code bases which wish to avoid panics.
### Test plan
Running:
`TESTNAME=unwrap_in_result cargo uitest

Corrects the float_equality_without_abs lint

Fixes an issue in the `float_equality_without_abs` lint. The lint suggestion was configured in a way that it lints the whole error and not just the subtraction part. In the current configuration the lint would suggest to change the expression in a wrong way, e.g.
```rust
let _ = (a - b) < f32::EPSILON; // before
let _ = (a - b).abs(); // after
```
This was dicovered by @flip1995. (See discussion of PR #5952).

Also the suggestion is now formatted via `utils::sugg`.

c7dc9c3cf7 Fix intermittent build error
The fmt test will cause clippy dev to be compiled and run. The clippy dev
dependencies are currently stored at `target/debug/deps` when this happens.
This location sometimes causes conflicts with ui tests which result in the
build error "thread 'compile_test' panicked at 'Found multiple rlibs for crate
`regex` ...".

This commit forces the clippy_dev dependencies to be stored under
`clippy_dev/target/` which seems to resolve this problem.

dd07860b83 Auto merge of #5941 - ThibsG:InlineInCopyPassByRef, r=yaahc
Don't lint if it has always inline attribute

Don't trigger the lint `trivially_copy_pass_by_ref` if it has `#[inline(always)]` attribute.

Note: I am not particularly familiar with `inline` impacts, so I implemented this the way that if only `#[inline]` attribute is here (without `always`), the lint will still trigger. Also, it will still trigger if it has `#[inline(never)]`.
Just tell me if it sounds too much conservative.

Widen understanding of prelude import

Prelude imports are exempt from wildcard import warnings. Until now only
imports of the form

```
use ...::prelude::*;
```

were considered. This change makes it so that the segment `prelude` can
show up anywhere, for instance:

```
use ...::prelude::v1::*;
```

Fixes #5917
