internal: Undo special bracket classification for attributes in vscode config
I changed this thinking the `#` could be considered part of the bracket but on second though I don't think that's quite right in general.
Fixes https://github.com/rust-lang/rust-analyzer/issues/16449
internal: add some `tracing` to {Request, Notification}Dispatch
Some of the tracing config would need to be changed in order to benefit more from this (especially `.with_span_events(FmtSpan::CLOSE)`), which provides span events like the following:
```
2024-01-18T02:41:06.675779Z INFO request{method="textDocument/codeLens" request_id=RequestId(I32(17))}: rust_analyzer::dispatch: close time.busy=61.8µs time.idle=5.29µs
```
I dunno if y'all need `LoggerFormatter` in here, but if you don't, I'd be happy to yeet it out of rust-analyzer. In any case, this provided a pretty decent amount of information in the logs, and I can expand this as needed or we can land this PR and expand later.
This commit also adds `tracing` to NotificationDispatcher/RequestDispatcher,
bumps `rust-analyzer-salsa` to 0.17.0-pre.6, `always-assert` to 0.2, and
removes the homegrown `hprof` implementation in favor of a vendored
tracing-span-tree.

Remove some unnecessary check logic for lang items in HIR typeck
Obvious bugs with `#[no_core]` do not deserve customized recovery logic, since they are bugs we do not expect users to ever encounter, and if users are experimenting with `#[no_core]`, they should really be familiar with the compiler implementation.
These error recoveries are implemented now only where issues have been reported in the past, rather than systematically validating lang items.
See https://github.com/rust-lang/compiler-team/issues/620
> In particular, one-off fixes for particular assumptions about lang items or intrinsics that introduce additional complexity into the compiler are not accepted.
r? Nilstrieb
Improve error message when `cargo build` is used to build the compiler
Inspired by #76446.
Doing it for `core` is probably higher value but also way harder because tools like cargo or rustc-build-sysroot would need to be fixed first, which I don't feel like doing.
Fix some `Arc` allocator leaks
This doesn't matter for the stable `Global` allocator as it is a ZST singleton, but other allocators may rely on all instances being dropped.
Revert outdated version of "Add the wasm32-wasi-preview2 target"
An outdated version of #119616 was merged in rollup #120309.
This reverts those changes to enable #119616 to “retain the intended diff” after a rebase.
```@rylev``` has agreed that this would be the cleanest approach with respect to the history.
Unblocks #119616.

r? `@nnethercote` since you recently did something similar.
There are so many more of these, but I wanted to get a PR out instead of growing the commit list indefinitely. The commits all work on their own and can be reviewed commit by commit.
Deduplicate more sized errors on call exprs
Change the implicit `Sized` `Obligation` `Span` for call expressions to include the whole expression. This aids the existing deduplication machinery to reduce the number of errors caused by a single unsized expression.
Suppress unhelpful diagnostics for unresolved top level attributes
Fixes#118455, unresolved top level attribute error didn't imported prelude and already have emitted an error, report builtin macro and attributes error by the way, so `check_invalid_crate_level_attr` in can ignore them.
Also fixes#89566, fixes#67107.

feat: "Normalize import" assist and utilities for normalizing use trees
- Add import/use tree normalization utilities
- Add "normalize import" assist
- Update "merge imports" assist to always apply to the covering use item except for nested use tree selections
- Update "merge imports" assist to avoid adding unnecessary braces when merging nested use tree selections
See [this discussion](https://github.com/rust-lang/rust-analyzer/pull/16372#discussion_r1457244321) for the motivation for the new "normalize import" assist and changes to the "merge imports" assist.

The query accept arbitrary DefIds, not just owner DefIds.
The return can be an `Option` because if there are no nodes, then it doesn't matter whether it's due to NonOwner or Phantom.
Also rename the query to `opt_hir_owner_nodes`.
feat: Support for GOTO def from *inside* files included with include! macro
close#14937
Try to implement goto def from *inside* files included with include! macro.
This implementation has two limitations:
1. Only **one** file which calls include! will be tracked. (I think multiple file be included is a rare case and we may let it go for now)
2. Mapping token from included file to macro call file (semantics.rs:646~658) works fine but I am not sure is this the correct way to implement.

Be more careful about interpreting a label/lifetime as a mistyped char literal.
Currently the parser interprets any label/lifetime in certain positions as a mistyped char literal, on the assumption that the trailing single quote was accidentally omitted. In such cases it gives an error with a suggestion to add the trailing single quote, and then puts the appropriate char literal into the AST. This behaviour was introduced in #101293.
This is reasonable for a case like this:
```
let c = 'a;
```
because `'a'` is a valid char literal. It's less reasonable for a case like this:
```
let c = 'abc;
```
because `'abc'` is not a valid char literal.
Prior to #120329 this could result in some sub-optimal suggestions in error messages, but nothing else. But #120329 changed `LitKind::from_token_lit` to assume that the char/byte/string literals it receives are valid, and to assert if not. This is reasonable because the lexer does not produce invalid char/byte/string literals in general. But in this "interpret label/lifetime as unclosed char literal" case the parser can produce an invalid char literal with contents such as `abc`, which triggers an assertion failure.
This PR changes the parser so it's more cautious about interpreting labels/lifetimes as unclosed char literals.
Fixes#120397.

std: Update documentation of seek_write on Windows
Currently the documentation of `FileExt::seek_write` on Windows indicates that writes beyond the end of the file leave intermediate bytes uninitialized. This commentary dates back to the original inclusion of these functions in #35704 (wow blast from the past!). At the time the functionality here was implemented using `WriteFile`, but nowadays the `NtWriteFile` method is used instead. The documentation for `NtWriteFile` explicitly states:
> If Length and ByteOffset specify a write operation past the current
> end-of-file mark, NtWriteFile automatically extends the file and updates
> the end-of-file mark; any bytes that are not explicitly written between
> such old and new end-of-file marks are defined to be zero.
This commentary has had a downstream impact in the `system-interface` crate where it tries to handle this by explicitly writing zeros, but I don't believe that's necessary any more. I'm sending a PR upstream here to avoid future confusion and codify that zeros are written in the intermediate bytes matching what Windows currently provides.
Fixes footnote handling in rustdoc
Fixes#100638.
You can now declare footnotes like this:
```rust
//! Reference to footnotes A[^1], B[^2] and C[^3].
//!
//! [^1]: Footnote A.
//! [^2]: Footnote B.
//! [^3]: Footnote C.

Move UI issue tests to subdirectories
I've moved issue tests numbered 1920, 3668, 5997, 23302, 32122, 40510, 57741, 71676, and 76077 to relevant better-named subdirectories (tracking issue #73494). The issues were chosen by having the highest number of files per issue.
I adjusted the `ISSUES_ENTRY_LIMIT` because `tidy` was shouting at me.
