Fixes#5405: redundant clone false positive with arrays
Check whether slice elements implement Copy before suggesting to drop
the clone method
changelog: add a check for slice indexing on redundant_clone lint
Update documentation for new_ret_no_self
changelog: Update documentation for lint new_ret_no_self to reflect that the return type must only contain `Self`, not be `Self`
The lint was changed to be more lenient than the documentation implies in PR #3338 (Related issue #3313)
Change the existing hex bit mask (`0x1111`) to a binary one (`0b1111`).
The former does not seem to have anything to do with trailing zeros and is
probably a typo.
Allow UUID style formatting for `inconsistent_digit_grouping` lint
This change adds a check to the `inconsistent_digit_grouping` to add a check for
NumericLiterals that follow the UUID format of 8-4-4-4-12.
If the NumericLiteral matches the UUID format, no further inconsistent grouping checks
will be performed.
Closes#5431

Check for clone-on-copy in argument positions
Earlier if arguments to method calls matched the above pattern they were
not reported. This patch ensures such arguments are checked as well.
Fixes#5436

Downgrade implicit_hasher to pedantic
From the [documentation](https://rust-lang.github.io/rust-clippy/master/index.html#implicit_hasher), this lint is intended to suggest:
```diff
- pub fn foo(map: &mut HashMap<i32, i32>) { }
+ pub fn foo<S: BuildHasher>(map: &mut HashMap<i32, i32, S>) { }
```
I think this is pedantic. I get that this lint can benefit core libraries like serde, but that's exactly the use case for pedantic lints; a library like serde will [enable clippy_pedantic](fd6741f4b0/src/lib.rs (L304)) and take the time to go through everything possible. Similar for libraries doing a libz blitz style checkup before committing to a 1.0 release; it would make sense to run through all the available pedantic lints then.
But otherwise, for most codebases and certainly for industrial codebases, the above suggested change just makes the codebase more obtuse for questionable benefit.
changelog: Remove implicit_hasher from default set of enabled lints
