11000: fix: insert whitespaces into assoc items for assist when macro generated r=Veykril a=Veykril
This is obviously only a temporary hack which still produces ugly looking items, but as long as the syntax is valid one can at least have rustfmt fix the formatting again.

10986: fix: Fix lint completions not working for unclosed attributes r=Veykril a=Veykril
Fixes#10682
Uses keywords and nested `TokenTree`s as a heuristic to figure out when to stop parsing in case the attribute is unclosed which should work pretty well as attributes are usually followed by either of those.

10976: fix: Show case-insensitive exact matches instead of fuzzy flyimport for short paths r=Veykril a=Veykril
And raise the fuzzy trigger from 2 to 3 chars. This way we keep the ability of flyimporting short names like `Rc`.

10847: fix: derive attr path handling in `replace_derive_with_manual_impl` r=rainy-me a=rainy-me
partially fixes#10666
renaming issues mentioned in https://github.com/rust-analyzer/rust-analyzer/issues/10666#issuecomment-955671021 doesn't seem to be fixable at this moment since it's not searchable?(not recorded?) by name.
<del>I'm not sure if it's appropriate to move `parse_comma_sep_paths` function to a method in `ast/node_ext`, maybe `ide_db::helpers` also make sense.</del> put into `ide_db::` instead.

This renames `descend_into_macros` to `descend_into_macros_single` and `descend_into_macros_many` into `descend_into_macros`.
However, this does not touch a function in `SemanticsImpl` of same name.
10440: Fix Clippy warnings and replace some `if let`s with `match` r=Veykril a=arzg
I decided to try fixing a bunch of Clippy warnings. I am aware of this project’s opinion of Clippy (I have read both [rust-lang/clippy#5537](https://github.com/rust-lang/rust-clippy/issues/5537) and [rust-analyzer/rowan#57 (comment)](https://github.com/rust-analyzer/rowan/pull/57#discussion_r415676159)), so I totally understand if part of or the entirety of this PR is rejected. In particular, I can see how the semicolons and `if let` vs `match` commits provide comparatively little benefit when compared to the ensuing churn.
I tried to separate each kind of change into its own commit to make it easier to discard certain changes. I also only applied Clippy suggestions where I thought they provided a definite improvement to the code (apart from semicolons, which is IMO more of a formatting/consistency question than a linting question). In the end I accumulated a list of 28 Clippy lints I ignored entirely.
Sidenote: I should really have asked about this on Zulip before going through all 1,555 `if let`s in the codebase to decide which ones definitely look better as `match` :P

Consider these expples
{ 92 }
async { 92 }
'a: { 92 }
#[a] { 92 }
Previously the tree for them were
BLOCK_EXPR
{ ... }
EFFECT_EXPR
async
BLOCK_EXPR
{ ... }
EFFECT_EXPR
'a:
BLOCK_EXPR
{ ... }
BLOCK_EXPR
#[a]
{ ... }
As you see, it gets progressively worse :) The last two items are
especially odd. The last one even violates the balanced curleys
invariant we have (#10357) The new approach is to say that the stuff in
`{}` is stmt_list, and the block is stmt_list + optional modifiers
BLOCK_EXPR
STMT_LIST
{ ... }
BLOCK_EXPR
async
STMT_LIST
{ ... }
BLOCK_EXPR
'a:
STMT_LIST
{ ... }
BLOCK_EXPR
#[a]

10152: feat: Add completion for raw identifiers r=matklad a=nabakin
Adds support for valid Rust completion of raw identifiers.
Previously, code completion of fields made via raw identifiers would not re-insert those raw identifiers, resulting in invalid Rust code. Now, code completion of fields made via raw identifiers do re-insert those raw identifiers, resulting in valid Rust code.
The same is true for all code completion instances for fields and compatible Rust identifiers.

10154: feat: Complete `#![recursion_limit = "N"]` instead of `#![recursion_limit = N]` r=lnicola a=hkmatsumoto

Today, rust-analyzer (and rustc, and bat, and IntelliJ) fail badly on
some kinds of maliciously constructed code, like a deep sequence of
nested parenthesis.
"Who writes 100k nested parenthesis" you'd ask?
Well, in a language with macros, a run-away macro expansion might do
that (see the added tests)! Such expansion can be broad, rather than
deep, so it bypasses recursion check at the macro-expansion layer, but
triggers deep recursion in parser.
In the ideal world, the parser would just handle deeply nested structs
gracefully. We'll get there some day, but at the moment, let's try to be
simple, and just avoid expanding macros with unbalanced parenthesis in
the first place.

9808: fix: Look for enum variants and trait assoc functions when looking for lang items r=matklad a=Veykril
Examples for lang enum variants are the `Option` variants.
Assoc trait functions aren't being seen since they aren't declared in the direct module scope.
