Add PROC_MACRO_TEST_TOOLCHAIN environment variable
This allows overriding the toolchain used to run `proc-macro-srv` tests.
---
Sample usage.
Testing the current ABI (variable unset/empty):
```shell
amos@tails ~/bearcove/rust-analyzer/crates/proc-macro-srv proc-macro-test-toolchain*
❯ PROC_MACRO_TEST_TOOLCHAIN="" cargo test --quiet
running 16 tests
................
test result: ok. 16 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out; finished in 0.01s
```
Testing an older ABI:
```shell
amos@tails ~/bearcove/rust-analyzer/crates/proc-macro-srv proc-macro-test-toolchain*
❯ PROC_MACRO_TEST_TOOLCHAIN="1.58" cargo test --quiet
running 16 tests
................
test result: ok. 16 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out; finished in 0.01s
```
Testing current nightly ABI:
```shell
❯ rustc +nightly --version
rustc 1.64.0-nightly (f8588549c 2022-07-18)
❯ PROC_MACRO_TEST_TOOLCHAIN="nightly" cargo test --quiet
running 16 tests
................
test result: ok. 16 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out; finished in 0.01s
```
Testing future ABI (`rust-lang/rust` master):
```shell
amos@tails ~/bearcove/rust-analyzer/crates/proc-macro-srv proc-macro-test-toolchain
❯ PROC_MACRO_TEST_TOOLCHAIN="stage1" cargo test --quiet
running 16 tests
..........thread '<unnamed>' panicked at 'range end index 216221164920373249 out of range for slice of length 18', library/core/src/slice/index.rs:73:5

Tagging `@jonas-schievink:` this might be helpful when updating versioned ABIs later on.
Add proc-macro-srv integration test that clones literals
This exercises some of the upcoming proc_macro bridge changes. It should also pass for all supported ABIs, with the older-style bridge.
This changed is tracked in:
* https://github.com/rust-lang/rust-analyzer/issues/12818
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 change is tracked in:
* https://github.com/rust-lang/rust-analyzer/issues/12818
Maintainer impact: none.

Remove `check_merge_commits` test
Due to the way "git subtree" works, the `check_merge_commits` test _will_ find merge commits and fail, so we simply skip it.
This changed is tracked in:
* https://github.com/rust-lang/rust-analyzer/issues/12818
Maintainer impact: none
Rationale: Merge commits will probably end up in
`rust-lang/rust-analyzer` when doing "rust=>ra" syncs anyway.
It could be changed to only check for merge commits in non-sync PRs,
but it's "probably not worth the hassle"
Rename proc macro server from 'Rustc' to 'RustAnalyzer'
Related to:
* https://github.com/rust-lang/rust-analyzer/issues/12818
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.
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.
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.
This change is tracked in:
* https://github.com/rust-lang/rust-analyzer/issues/12818
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.
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: Correctly generate default `PartialEq::ne`
Fixes#12779
For the `Generate default members` assist on the `PartialEq` trait, the assist will now give the default implementation instead of generating a function.
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.
fixes#12784
Upgrade to expect-test@1.4.0, add CARGO_WORKSPACE_DIR env var
This should make ra's test suite runnable from within `rust-analyzer/rust`.
`@cuviper` ran into that when trying to run RA tests from rust CI: https://github.com/rust-lang/rust/pull/99444#issuecomment-1188844202
chore: change str_ref_to_string to str_ref_to_owned
`ToString` is implemented by many different types than `&str`, and represents a serialization into string data. The fact that said data is returned as owned, is an implementation detail resulting from the lack of a parameter for a pre-allocated buffer.
If merely copying borrowed string data to owned string data is all that is desired, `ToOwned` is a much better choice, because if the user later refactors the code such that the input is no longer an `&str`, then they will get a compiler error instead of a mysterious runtime-behavioral change.
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.
fixes#12784
Add simple support for completion item details
Supercedes https://github.com/rust-lang/rust-analyzer/pull/9891
This doesn't yet really implement anything new, it just adds the scaffolding for the protocol conversion

fix: make file watcher config a drop-down (and clarify the options)
Fixes https://github.com/rust-lang/rust-analyzer/issues/12794
Also renames "notify" to "server", since that's clearer ("notify" is still accepted for compatibility).
