rustdoc: remove no-op CSS `.block { padding: 0 }`
This rule was changed in 8fb1250aba8135679463351a3813c04ae45bf311 from the original version that had a non-zero padding. It's not needed, because it's not overriding anything that would've given `.block` a padding.

rustdoc: use more precise URLs for jump-to-definition links
As an example, this cuts down <https://doc.rust-lang.org/nightly/nightly-rustc/src/rustc_middle/ty/mod.rs.html> by about 11%.
$ du -h new_mod.rs.html old_mod.rs.html
296K new_mod.rs.html
332K old_mod.rs.html
Like https://github.com/rust-lang/rust/pull/83237, but separate code since source links have a different URL structure.

Rollup merge of #101813 - GuillaumeGomez:check-css-variables, r=notriddle
Extend CSS check to CSS variables
This PR is a bit big because the first commit is a rewrite of the CSS parser to something a bit simpler which still allows to get easily access to CSS properties name.
The other two are about adding tests and adding the CSS variables check.
This check was missing because we are relying more and more on CSS variables rather than CSS selectors in themes.

rustdoc mobile: move notable traits to return type
These were originally on the left, but were moved to the return type in c90fb7185a5febb00b7f8ccb49abceacd41bad6e. The CSS rule for mobile did not get updated at the time, so updating it now.
check_missing_items.py was a python script that checked rustdoc json output to make sure all the Id's referenced existed in the JSON index. This PR replaces that with a rust binary (`jsondoclint`) that does the same thing.
### Motivation
1. Easier to change when `rustdoc-json-types` changes, as `jsondoclint` uses the types directly.
2. Better Errors:
- Multiple Errors can be emited for a single crate
- Errors can say where in JSON they occored
```
2:2889:408 not in index or paths, but refered to at '.index."2:2888:104".inner.items[0]'
2:2890:410 not in index or paths, but refered to at '.index."2:2888:104".inner.items[1]'
```
3. Catches more bugs.
- Because matches are exaustive, all posible variants considered for enums
- All Id's checked
- Has already found #101770, #101199 and #100973
- Id type is also checked, so the Id's in a structs fields can only be field items.
4. Allows the possibility of running from `rustdoc::json`, which we should do in a crator run at some point.

Prefer explict closure sig types over expected ones
fixes #100800
Previously we only checked that given closure arguments are equal to expected closure arguments, but now we choose the given closure arguments for the signature that is used when type checking the closure body, and keep the other signature for the type of the closure as seen outside of it.
Rollup merge of #101738 - dpaoliello:linkname, r=petrochenkov
Fix `#[link kind="raw-dylib"]` to respect `#[link_name]`
Issue Details:
When using `#[link kind="raw-dylib"]` (#58713), the Rust compiler ignored any `#[link_name]` attributes when generating the import library and so the resulting binary would fail to link due to missing symbols.
Fix Details:
Use the name from `#[link_name]` if present when generating the `raw-dylib` import library, otherwise default back to the actual symbol name.

Reorder nesting scopes and declare bindings without drop schedule
Fix #99228
Fix #99975
Storages are previously not declared before entering the `else` block of a `let .. else` statement. However, when breaking out of the pattern matching into the `else` block, those storages are recorded as scheduled for drops. This is not expected.
This MR fixes this issue by not scheduling the drops for those storages.
Auto merge of #101173 - jyn514:simplify-macro-arguments, r=cjgillot
Further simplify the macros generated by `rustc_queries`
This doesn't actually move anything outside the macros, but it makes them simpler to read.
- Add a new `rustc_query_names` macro. This allows a much simpler syntax for the matchers in the macros passed to it as a callback.
- Convert `define_dep_nodes` and `alloc_once` to use `rustc_query_names`. This is possible because they only use the names
(despite the quite complicated matchers in `define_dep_nodes`, none of the other arguments are used).
- Get rid of `rustc_dep_node_append`.
Auto merge of #101811 - flip1995:clippyup, r=flip1995
Clippy pre beta branch fix
Before beta is branched on Friday, I want to move the `unused_peekable` lint that was added in this release cycle (1.65) to `nursery`. This lint was already reported twice (https://github.com/rust-lang/rust-clippy/issues/9456, https://github.com/rust-lang/rust-clippy/issues/9462) in a short time, so it is probably a good idea to fix it before it hits beta and then stable.

Auto merge of #101620 - cjgillot:compute_lint_levels_by_def, r=oli-obk
Compute lint levels by definition
Lint levels are currently computed once for the whole crate. Any code that wants to emit a lint depends on this single `lint_levels(())` query. This query contains the `Span` for each attribute that participates in the lint level tree, so any code that wants to emit a lint basically depends on the spans in all files in the crate.
Contrary to hard errors, we do not clear the incremental session on lints, so this implicit world dependency pessimizes incremental reuse. (And is furthermore invisible for allowed lints.)
This PR completes https://github.com/rust-lang/rust/pull/99634 (thanks for the initial work `@fee1-dead)` and includes it in the dependency graph.
The design is based on 2 queries:
1. `lint_levels_on(HirId) -> FxHashMap<LintId, LevelAndSource>` which accesses the attributes at the given `HirId` and processes them into lint levels. The `TyCtxt` is responsible for probing the HIR tree to find the user-visible level.
2. `lint_expectations(())` which lists all the `#[expect]` attributes in the crate.
This PR also introduces the ability to reconstruct a `HirId` from a `DepNode` by encoding the local part of the `DefPathHash` and the `ItemLocalId` in the two `u64` of the fingerprint. This allows for the dep-graph to directly recompute `lint_levels_on` directly, without having to force the calling query.
Auto merge of #101313 - SparrowLii:mk_attr_id, r=cjgillot
make `mk_attr_id` part of `ParseSess`
Updates #48685
The current `mk_attr_id` uses the `AtomicU32` type, which is not very efficient and adds a lot of lock contention in a parallel environment.
This PR refers to the task list in #48685, uses `mk_attr_id` as a method of the `AttrIdGenerator` struct, and adds a new field `attr_id_generator` to `ParseSess`.
`AttrIdGenerator` uses the `WorkerLocal`, which has two advantages: 1. `Cell` is more efficient than `AtomicU32`, and does not increase any lock contention. 2. We put the index of the work thread in the first few bits of the generated `AttrId`, so that the `AttrId` generated in different threads can be easily guaranteed to be unique.
Auto merge of #101212 - eholk:dyn-star, r=compiler-errors
Initial implementation of dyn*
This PR adds extremely basic and incomplete support for [dyn*](https://smallcultfollowing.com/babysteps//blog/2022/03/29/dyn-can-we-make-dyn-sized/). The goal is to get something in tree behind a flag to make collaboration easier, and also to make sure the implementation so far is not unreasonable. This PR does quite a few things:
* Introduce `dyn_star` feature flag
* Adds parsing for `dyn* Trait` types
* Defines `dyn* Trait` as a sized type
* Adds support for explicit casts, like `42usize as dyn* Debug`
* Including const evaluation of such casts
* Adds codegen for drop glue so things are cleaned up properly when a `dyn* Trait` object goes out of scope
* Adds codegen for method calls, at least for methods that take `&self`
Quite a bit is still missing, but this gives us a starting point. Note that this is never intended to become stable surface syntax for Rust, but rather `dyn*` is planned to be used as an implementation detail for async functions in dyn traits.
Joint work with `@nikomatsakis` and `@compiler-errors.`
