8283: Resolve associated types r=flodiebold a=Veykril
Prior we were only resolving paths until the first type was found, then discarding the result if the path wasn't fully consumed. That of course causes associated types to not resolve. Fixes#5003

8267: Adding gifs and screenshots for features in manual r=matklad a=MozarellaMan
For #6539
This includes most of gif or screenshot examples of most items in the "Features" header. With the exceptions of:
- **On Typing Assists** - couldn't get it to work for a demo, I'm probably missing something?
- **Structural search and replace** - looked to be already a visual example of the feature
- **Workspace symbol** - wasn't sure how best to show this, all of the examples maybe? Also wasn't sure of the best code example to show it off
- **Semantic Syntax Highlighting** - seemed obvious enough to not need a screenshot, but I could easily add this
All the gifs/pngs are hosted in this [comment](https://github.com/rust-analyzer/rust-analyzer/issues/6539#issuecomment-809574840). Please let me know if any of them aren't suitable (and why) and I'll improve it! Or if you don't like the theme/font

8083: Track source file IDs in source mapping of Attrs r=jonas-schievink a=Veykril
Fixes the panics/incorrect injection highlighting of outline module declarations until we figure out a nicer source mapping strategy for attributes.

7900: show function params in completion detail r=matklad a=JoshMcguigan
This resolves#7842 by updating the detail for function completions from `-> T` to `fn(T, U) -> V`. I added an expicit unit test for this, `ide_completion::render::fn_detail_includes_args_and_return_type`, which passes.
Lots of other unit tests fail (~60 of them) due to this change, although I believe the failures are purely cosmetic (they were testing the exact format of this output). I'm happy to go update those tests, but before I do that I'd like to make sure this is in fact the format we want for the detail?
edit - I realized `UPDATE_EXPECT=1 cargo test` automatically updates `expect!` tests. Big 👍 to whoever worked on that! So I'll go ahead and update all these tests soon. But I still would like to confirm `fn(T, U) -> V` is the desired content in the `detail` field.

8020: Power up goto_implementation r=matklad a=Veykril
by allowing it to be invoked on references of names, now showing all (trait)
implementations of the given type in all crates instead of just the defining
crate as well as including support for builtin types
Example screenshot of `impl`s of Box in `log`, `alloc`, `std` and the current crate. Before you had to invoke it on the definition where it would only show the `impls` in `alloc`.

What happens here is that we lower `: ` to a missing expression, and
then correctly record that the corresponding field expression resolves
to a specific field. Where we fail is in the mapping of syntax to this
missing expression. Doing it via `ast_field.expr()` fails, as that
expression is `None`. Instead, we go in the opposite direcition and ask
each lowered field about its source.
This works, but has wrong complexity `O(N)` and, really, the
implementation is just too complex. We need some better management of
data here.
8021: Enable searching for builtin types r=matklad a=Veykril
Not too sure how useful this is for reference search overall, but for completeness sake it should be there
Also enables document highlighting for them.
8022: some clippy::performance fixes r=matklad a=matthiaskrgr
use vec![] instead of Vec::new() + push()
avoid redundant clones
use chars instead of &str for single char patterns in ends_with() and starts_with()
allocate some Vecs with capacity to avoid unnecessary resizing

7966: Diagnose files that aren't in the module tree r=jonas-schievink a=jonas-schievink
Fixes https://github.com/rust-analyzer/rust-analyzer/issues/6377
I'm not sure if this is the best way to do this. It will cause false positives for all `include!`d files (though I'm not sure how much IDE functionality we have for these).

7795: Show docs on hover for keywords and primitives r=matklad a=Veykril
It's a bit annoying that this requires the `SyntaxNode` and `Semantics` to be pulled through `hover_for_definition` just so we can get the `std` crate but I couldn't think of a better way.

7335: added region folding r=matklad a=LucianoBestia
Regions of code that you'd like to be folded can be wrapped with `// #region` and `// #endregion` line comments.
This is called "Region Folding". It is originally available for many languages in VSCode. But Rust-analyzer has its own folding function and this is missing.
With this Pull Request I am suggesting a simple solution.
The regions are a special kind of comments, so I added a bit of code in the comment folding function.
The regex to match are: `^\s*//\s*#?region\b` and `^\s*//\s*#?endregion\b`.
The number of space characters is not important. There is an optional # character. The line can end with a name of the region.
Example:
```rust
// 1. some normal comment
// region: test
// 2. some normal comment
calling_function(x,y);
// endregion: test
```
I added a test for this new functionality in `folding_ranges.rs`.
Please, take a look and comment.
I found that these exact regexes are already present in the file `language-configuration.json`, but I don't find a way to read this configuration. So my regex is hardcoded in the code.
7691: Suggest name in extract variable r=matklad a=cpud36
Generate better default name in extract variable assist as was mentioned in issue #1587
# Currently supported
(in order of declining precedence)
1. Expr is argument to a function; use corresponding parameter name
2. Expr is result of a function or method call; use this function/method's name
3. Use expr type name (if possible)
4. Fallback to `var_name` otherwise
# Showcase
# Questions
* Should we more aggressively strip known types? E.g. we already strip `&T -> T`; should we strip `Option<T> -> T`, `Result<T, E> -> T`, and others?
* Integers and floats use `var_name` by default. Should we introduce a name, like `i`, `f` etc?
* Can we return a list and suggest a name when renaming(like IntelliJ does)?
* Should we add counters to remove duplicate variables? E.g. `type`, `type1`, type2`, etc.

7778: Fix lowering trailing self paths in UseTrees r=Veykril a=Veykril
Noticed that hovering over `self` in a use tree like `use foo::bar::{self}` showing documentation and such for the current module instead of `bar`.
