Again a big **thank you** for everyone who helped to collect the abbreviation list over on [zulip]. I had a lot of fun, and it was also very informative. Keep up the good work :upside_down_face:

Auto merge of #6591 - camsteffen:manual-filter-map, r=llogiq
`manual_filter_map` and `manual_find_map`
changelog: Add `manual_filter_map` and replace `find_map` with `manual_find_map`
Replaces #6453
Fixes #3188
Fixes #4193
~Depends on #6567 (to fix an internal lint false positive)~
This replaces `filter_map` and `find_map` with `manual_filter_map` and `manual_find_map` respectively. However, `filter_map` is left in place since it is used for a variety of other cases. See discussion in #6453.

Fix the reversed suggestion message of `stable_sort_primitive`.
Now Clippy emits `stable_sort_primitive` warning as follows:
```
warning: used sort instead of sort_unstable to sort primitive type `usize`
--> src\asm.rs:41:13
|
41 | self.successors.sort();
| ^^^^^^^^^^^^^^^^^^^^^^ help: try: `self.successors.sort_unstable()`

= note: `#[warn(clippy::stable_sort_primitive)]` on by default
= help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#stable_sort_primitive

I think the position of `sort` and `sort_unstable` in the first line should be reversed.

Fix path_to_res for enum inherent items

I tried to add `Option::is_some` to the paths but got a false positive from the invalid paths lint. Turns out the `path_to_res` function does not find inherent impls for enums. I fixed this and took the liberty to do some additional cleanup in the method.

size_of_in_element_count: Disable lint on division by byte-size
Fixes #6511
It is fairly common to divide some length in bytes by the byte-size of a single element before creating a `from_raw_parts` slice or similar operation. This lint would erroneously disallow such expressions.
Just in case, instead of simply disabling this lint in the RHS of a division, keep track of the inversion and enable it again on recursive division.

size_of_in_element_count: Separate test file in expressions and functions
An upcoming test case for new expresssion variants make the stderr file
go over 200 lines. Split this test case in two to have a clear
distinction between checking whether the lint is still applying on
all the functions with member counts as argument, versus validating
various member-count expressions that may or may not be invalid.

Auto merge of #6608 - rail-rain:note_on_as_conversions, r=phansch
Add a note to `as_conversions`
I have seen a couple of examples where there are some misunderstandings of `as_conversions` ([1](https://github.com/rust-lang/rust-clippy/issues/5890#issuecomment-671852546), [2](https://github.com/rust-lang/rust-clippy/issues/6116#issuecomment-704251710) and [3](https://github.com/rust-lang/rust-clippy/issues/6428)). This PR adds the note that explains its purpose and relationship with other `as` related casts. Open question: should I list every related lints for discoverbility, or just suggest how to find these? I chose the former because there's no way to list only and all `as` related lints (e.g. on All the Clippt Lints, 'cast' includes some noises, but `cast_` excludes some) even though I cannot guarantee the list will be updated to include future changes.

changelog: Add a note to the document of `as_conversions`
This will trigger on any type which implements `Index<RangeFull>` that returns the input type. This would be a false positive if the implementation does something other than return itself, but I'm not sure why you would ever want to do that.

Separate out a `hir::Impl` struct
This makes it possible to pass the `Impl` directly to functions, instead
of having to pass each of the many fields one at a time. It also
simplifies matches in many cases.
This is the first time Clippy gets its own roadmap. The reason for this roadmap is, that with the Rust language growing, also Clippy is growing. With this keeping track of and implementing bigger projects gets quite hard. This roadmap should help in exactly this regard.
After having the approval of this roadmap by the Clippy team, we want to know from the community:
- What do you think in general about this roadmap?
- Are there any pain points in Clippy, that should be included here?
- What of the points listed here has the highest priority for you?

I can't find a good test case for this, so it could be too much conservative.
