Tweak pedantic description for occasional FPs

changelog: none

Okay this is getting a bit picky (you might even say pedantic). I think we need to be careful not use the pedantic category as cover-all for lints with any amount of false positives. Lints with a high degree of FPs should be nursery or restriction IMO. If the pedantic category were to yield, say hypothetically, over 50% FPs, it would just be too annoying to use at all (to be sure, "too picky for me" is not a FP).

Change `while_let_on_iterator` suggestion to use `by_ref()`

It came up in the discussion #7659 that suggesting `iter.by_ref()` is a clearer suggestion than `&mut iter`. I personally think they're equivalent, but if `by_ref()` is clearer to people then that should be the suggestion.

New lint: `same_name_method`

changelog: ``[`same_name_method`]``
fix: https://github.com/rust-lang/rust-clippy/issues/7632

It only compares a method in `impl` with another in `impl trait for`
It doesn't lint two methods in two traits.

I'm not sure my approach is the best way. I meet difficulty in other approaches.

2316f4da83 Auto merge of #7671 - dtolnay-contrib:singlecharnames, r=xFrednet
Downgrade many_single_char_names to pedantic

As suggested by `@flip1995` in https://github.com/rust-lang/rust-clippy/issues/7666#issuecomment-918993215, by today's standards this lint would be considered `pedantic`.

This is one of the most widely suppressed Clippy lints on crates.io according to https://github.com/dtolnay/noisy-clippy.

In my opinion this lint is just too domain specific for Clippy to have reliable visibility into. Sure there are some cases where the author is just being lazy and could use a kick in the butt, but we're still left with an enormous number of suppressions where single chars are the most appropriate name. For example in the context of colors, a function using `h`, `s`, `l`, `r`, `g`, `b` is 100% sensible and spelling all those out is silly, but it's past the default lint threshold.

746a0051c3 Auto merge of #7640 - kneasle:mut-key-false-positive, r=camsteffen
Improve accuracy of `mut_key`

Fixes #6745.

Whilst writing the tests for this, I noticed what I believe is a false negative (the code in `@xFrednet's` [comment](https://github.com/rust-lang/rust-clippy/issues/6745#issuecomment-909658267) doesn't trigger the lint).  Currently the tests contain a case for this (which is blatantly ignored), but I'm not at all sure how to implement this (since the lint currently behaves completely differently for ADTs).  I'm not sure what should be done - on the one hand the extra test cases are misleading, but on the other hand they don't cause much harm and would save effort for anyone fixing that false negative.

Target directory cleanup

changelog: none

* .cargo/config now has `target-dir` specified so that it is inherited by child projects. The target directory needs to be shared with clippy_dev, but not necessarily at the project root. (cc #7625)
* Uses `std::env::current_exe` (and its parent directories) whenever possible
* `CLIPPY_DRIVER_PATH` and `TARGET_LIBS` are no longer required from rustc bootstrap (but `HOST_LIBS` still is). These can be removed from the rustc side after merging.
* `CLIPPY_DOGFOOD` and the separate target directory are removed. This was originally added to mitigate #7343.
