75e983a518 Auto merge of #5125 - Areredify:too_many_bools, r=flip1995
Port mitsuhiko's excessive bools lints

Closes #4 .
changelog: add `struct_excessive_bools` and `fn_params_excessive_bools` lints.
I moved is_trait_impl_item check because at first I implemented it as a late pass for some reason but then I realized it's actually an early lint. But it's a useful function to have, should I move it into a separate pr?

Do not lint `unnecessary_unwrap` in external macros

Fixes #5131

I think we shouldn't lint `{panicking, unnecessary}_unwrap` in macros, not just `assert!`.

dont fire `possible_missing_comma` if intendation is present

Closes #4399
changelog: dont fire `possible_missing_comma` if intendation is present

I suspect there is already a utils function for indentation (but searching indent didn't yield a function for that), and my solution is certainly not universal, but it's probably the best we can do.

add size parameter for `vec_box`  lint

changelog: add size threshold for the `vec_box` lint, currently 4096 bytes (one page) (subject to change). Closes #3547.

diff is a little bit confusing due to some refactoring (moving free functions to lint struct functions), relevant portion is [this](https://github.com/rust-lang/rust-clippy/compare/master...Areredify:vec_box_threshold?expand=1#diff-1096120ca9143af89dcc9175ea92b54aR294-R298).

Match wild err arm improvements

This lint should trigger on other identifiers which have `_` prefix (such as `_e`) and only if they are unused in the panic block.

_Note_: the `is_unused` function is greatly inspired from `pat_is_wild` function in [loops lints](43ac9416d9/clippy_lints/src/loops.rs (L1689)).
I've been considering doing some refactoring, maybe in utils. Maybe this PR or a new one. What do you think ?

fa9b85d4df Auto merge of #4881 - krishna-veerareddy:issue-4871-use-mem-take, r=flip1995
Use `mem::take` instead of `mem::replace` when applicable

`std::mem::take` can be used to replace a value of type `T` with `T::default()` instead of `std::mem::replace`.

Fixes issue #4871

changelog: Added lint for [`mem_replace_with_default`]

Fix ICE on `unsound_collection_transmute`

Fixes #4968

Check if `Ty`s are normalizable. It might show hidden false negative, I'm not sure.
Also, the regression tests are placed on two dirs, so move them to `/crashes`. I think it will be easier to find the right place.

84a60c3186 Prevent replace_consts lint within match patterns
Currently `replace_consts` lint applies within match patterns but
the suggestion is incorrect as function calls are disallowed in
them. To fix this we prevent the lint from firing within patterns.
