6198: Skip macro matcher fragment name semantic highlighting r=matklad a=Veykril
Implements a small state-machine for macro_rules! highlighting to separate out the matcher part of its rules. This skips semantically highlighting names of metavariables in the matcher and expander. This might even allow for more fun macro highlighting things in the future.
Fixes#4380.

6199: Fix `mut self` not emitting mutable binding on `self` use r=matklad a=Veykril
Prior to this, when `self` in a function is taken by value and bound mutably, its use inside of the method body won't be marked `mutably`.
Fixes#5461

5917: Add a command to open docs for the symbol under the cursor r=matklad a=zacps
#### Todo
- [ ] Decide if there should be a default keybind or context menu entry
- [x] Figure out how to get the documentation path for methods and other non-top-level defs
- [x] Design the protocol extension. In future we'll probably want parameters for local/remote documentation URLs, so that should maybe be done in this PR?
- [x] Code organisation
- [x] Tests

Return an error with a meaningful message for requests to
`textDocument/rename` if the operation cannot be performed.
Pass errors raised by rename handling code to the LSP runtime.
As a consequence, the VS Code client shows and logs the request
as if a server-side programming error occured.

Previously, "find all references" on a variant field wouldn't find any
references outside the defining module. This is because variant fields
were incorrectly assumed to be private, like struct fields without
explicit visibility, but they actually inherit the enum's visibility.
5651: Add track_env_var to the proc macro server r=kjeremy a=lnicola
See https://github.com/rust-lang/rust/pull/74653.
Fixes#6054.
Fixes#5640, maybe.
Should be merged when 1.47 is released.
Proc macros still don't work for me, but it no longer crashes.

Currently a method only has defaultness if it is a provided trait
method, but this will change when specialisation is available and may
need to become a concept known to hir.
I opted to go for a 'fewest changes' approach given specialisation is
still under development.
6161: Bump chalk to use latest git to get upstream fix r=jonas-schievink a=Ameobea
* Chalk very recently (like an hour ago) merged a fix that prevents rust analyzer from panicking. This allows it to be usable again for code that hits those situations. See #6134, #6145, Probably #6120

6154: Shorten type hints for std::iter Iterators r=SomeoneToIgnore a=Veykril
Fixes#3750.
This re-exports the `hir_expand::name::known` module to be able to fetch the `Iterator` and `iter` names.
I'm not sure if there is anything to do with `Solution::Ambig` in `normalize_trait_assoc_type` or whether discarding those results is always wanted.

Percentage is a UI concern, the physical fact here is fraction. It's
sad that percentage bleeds into the protocol level, we even duplicated
this bad API ourselves!
6158: Fix for negative literals in macros r=matklad a=cutsoy
_This pull request fixes #6028._
When writing `-42.0f32` in Rust, it is usually parsed as two different tokens (a minus operator and a float literal).
But a procedural macro can also generate new tokens, including negative [float literals](https://doc.rust-lang.org/stable/proc_macro/struct.Literal.html#method.f32_suffixed):
```rust
#[proc_macro]
fn example_verbose(input: TokenStream) -> TokenStream {
let literal = Literal::f32_suffixed(-42.0);
quote! { #literal }
}
```
or even shorter
```rust
#[proc_macro]
fn example(input: TokenStream) -> TokenStream {
let literal = -42.0f32;
quote! { #literal }
}
```
Unfortunately, these currently cause RA to crash:
```
thread '<unnamed>' panicked at 'Fail to convert given literal Literal {
text: "-42.0f32",
id: TokenId(
4294967295,
),
}', crates/mbe/src/subtree_source.rs:161:28
```
This pull request contains both a fix 8cf9362 and a unit test 27798ee. In addition, I installed the patched server with `cargo xtask install --server` and verified in VSCode that it no longer crashes when a procedural macro returns a negative number literal.
