proc_macro/bridge: send diagnostics over the bridge as a struct
This removes some RPC when creating and emitting diagnostics, and
simplifies the bridge slightly.
After this change, there are no remaining methods which take advantage
of the support for `&mut` references to objects in the store as
arguments, meaning that support for them could technically be removed if
we wanted. The only remaining uses of immutable references into the
store are `TokenStream` and `SourceFile`.

Small fixups
- use `path` instead of `paths`
- don't mark rust-analyzer as an optional tool
- print the cargo command that's run in the proc-macro-test build script
this originally was part of a change to fix `test --stage 0 rust-analyzer`,
but I'm going to leave that for a separate PR so it's easier to review.

Is this what you were thinking of here, `@Veykril` ? I haven't done any work on completions before, so I could definitely be misunderstanding the issue.
Auto merge of #12847 - Veykril:vscode-downgrade, r=Veykril
fix: Fix restart server duplicating language clients
Reverts 03a62c180e6a7300d0d7b8c4d680b749c101bcbb
vscode-languageclient@8.0.0-next.15 and beyond changed the behaviour of language clients to be automatically started if a request comes in while they are not running. Currently when we restart the server via the restart command we recreate the language client, which causes VSCode to restart the stopped server, effectively duplicating our language clients...
Reverting the commit is simpler right now, the proper fix would be to only create a language client once and then use the `restart` functionality on it instead.
internal: Use ItemTree for variant, field and module attribute collection in attrs_query
Less parsing = very good, should speed up lang item collection as that basically probes attributes of all enum variants which currently triggers parsing
Not fond of how this is searching for the correct index, ideally we'd map between HIR and item tree Id here but I am not sure how, storing the item tree ids in the HIR version doesn't work due to the usage of `Trace`...
Otherwise, fall back to the multi ABI scheme, except in testing, where
it becomes a hard error.
This should make it possible to use a rustup-provided rust-analyzer with
proc macro dylibs compiled by older rustcs, and it'll also catch changes
to the format of `rustc --version` or the `.rustc` section that would
make them impossible to compare for equality.

Build proc-macro-test-impl out-of-tree
Building it in-place fails in rust CI because the source directory is read-only. This changes `proc-macro-test`'s build script to first
copy `imp` under `OUT_DIR` (which is read-write).
It also prints stdout/stderr for the nested cargo invocation, should it fail. (I've seen failures in rust CI that I couldn't explain, and
when they take 25 minutes to reproduce, you want to have that info)

This is mostly a courtesy PR for the sake of rustc maintainers. When they looked at `proc-macro-srv`, they noticed the server was named `Rustc` — probably because of historical copy-paste. Only rustc's proc macro server should be named `Rustc`, ra's can be named `RustAnalyzer`.
Maintainer impact: There's no semantic changes in this PR, only naming. One test snapshot was updated since "proc macro server types" were used to test traits somewhere else and I renamed those too, why not.
Allow merge commits when 'in-rust-tree' feature is enabled
This adds an `in-rust-tree` feature that will be enabled when
rust-analyzer is built from `rust-lang/rust`. Due to the way
"git subtree" works, that test _will_ find merge commits and
fail, so we simply skip it.
Auto merge of #12826 - fasterthanlime:in-tree-warnings, r=Veykril
Enable (and fix) extra lint groups required for in-tree build
This enables 3 lint groups that are required to build rust-analyzer as an "in-tree" (git subtree) tool in `rust-lang/rust`, and fixes all relevant diagnostics.
Maintainer impact: more warnings, should be easy enough to fix them (it's mostly looking out for "rust-2015-isms", the lint group is poorly named). If you forget some, they'll show up during a `ra=>rust` sync.
This PR fixes #11897 by escaping '\\' and '$' in the text of the receiver position expression. See [here](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#snippet_syntax) for the specification of the snippet syntax (especially [this section](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#grammar) discusses escaping).
Although not all occurrences of '\\' and '$' have to be replaced, I chose to replace all as that's simpler and easier to understand. There *are* more clever ways to implement it, but I thought they were premature optimization for the time being (maybe I should put FIXME notes?).
Auto merge of #12811 - TopGunSnake:12790, r=Veykril
fix: Insert `pub(crate)` after doc comments and attribute macros
Fixes #12790
Original behavior was to insert `pub(crate)` at the `first_child_or_token`, which for an item with a comment or attribute macro, would put the visibility marker before the comment or macro, instead of after.
This merge request alters the call to find the node with appropriate `SyntaxKind` in the `children_or_tokens`. It also adds a test case to the module to verify the behavior. Test case verifies function, module, records, enum, impl, trait, and type cases.

fix: Prevent panic in Remove Unused Parameter assist
Instead of calling `builder.delete` for every text range we find with
`process_usage`, we now ensure that the ranges do not overlap before removing
them. If a range is fully contained by a prior one, it is dropped.
