Remove `box_syntax`
r? `@Nilstrieb`
This removes the feature `box_syntax`, which allows the use of `box <expr>` to create a Box, and finalises removing use of the feature from the compiler. `box_patterns` (allowing the use of `box <pat>` in a pattern) is unaffected.
It also removes `ast::ExprKind::Box` - the only way to create a 'box' expression now is with the rustc-internal `#[rustc_box]` attribute.
As a temporary measure to help users move away, `box <expr>` now parses the inner expression, and emits a `MachineApplicable` lint to replace it with `Box::new`
Closes #49733

rustdoc: reduce allocs in FnDecl::inner_full_print
Instead of maintaining parallel buffers for both HTML and non-HTML output, follow the idiom from the rest of format.rs that f.alternate() == true means textual output. Also, add an argument to control line wrapping explicitly.
This allows the caller to render once with textual output and no line wrapping, to decide whether line wrapping should be applied in the final HTML output.
Also, remove some format! and " ".repeat calls, and remove a dependency on calling `String::replace` to switch from newlines to spaces.
This coincidentally fixes some minor bugs where the old code was undercounting the number of characters for a declaration in text mode.

Strengthen state tracking in const-prop
Some/many of the changes are replicated between both the const-prop lint and the const-prop optimization.
Behaviour changes:
- const-prop opt does not give a span to propagated values. This was useless as that span's primary purpose is to diagnose evaluation failure in codegen.
- we remove the `OnlyPropagateInto` mode. It was only used for function arguments, which are better modeled by a write before entry.
- the tracking of assignments and discriminants make clearer that we do nothing in `NoPropagation` mode or on indirect places.

Add eslint check for rustdoc-gui tester

Rename `config.toml.example` to `config.example.toml`
This had bothered me for a while as it leads to bad (missing) syntax highlighting in most editors I've used, and `@jyn514` suggested I just make the change and that the compatibility concerns I had don't really matter.
I suspect it will be a contentious one, so will not be offended if the outcome of this is to close the PR.

rustdoc: use restricted Damerau-Levenshtein distance for search
Based on https://github.com/rust-lang/rust/pull/108200, for the same rationale.
> This replaces the existing Levenshtein algorithm with the Damerau-Levenshtein algorithm. This means that "ab" to "ba" is one change (a transposition) instead of two (a deletion and insertion). More specifically, this is a restricted implementation, in that "ca" to "abc" cannot be performed as "ca" → "ac" → "abc", as there is an insertion in the middle of a transposition. I believe that errors like that are sufficiently rare that it's not worth taking into account.
Before this change, searching [`prinltn!`] listed `print!` first, followed by `println!`. With this change, `println!` matches more closely.
[`prinltn!`]: https://doc.rust-lang.org/nightly/std/?search=prinltn!

bootstrap: document tidy
Enable documentation of tidy, as suggested in #106803. Jyn mentioned they should probably be added to `doc.rust-lang.org`, how should that be done?

Some comments may be formed like:
// This function takes a tuple `(Vec<String>,
// Box<[u8]>)` and transforms it into `Vec<u8>`.
where the "back-ticked" section wraps around.
Therefore, we can't make a single-line based
lint.
We also cannot make the lint paragraph based,
as it would otherwise complain about inline
code blocks:
/// ```
/// use super::Foo;
///
/// fn main() { Foo::new(); }
/// ```
For the future, one could introduce some checks
to treat code blocks specially, but such code
would make the check even more complicated.

This updates the host compiler for dist-x86_64-linux to LLVM 16,
pulling in the BOLT fix at
https://github.com/llvm/llvm-project/commit/1de305da428598d79b7d2d9e70962130142f7ca4,
which is needed to update Rust to LLVM 16.

Directly construct Inherited in typeck.
Using `InheritedBuilder` + a closure does not seem necessary any more.
+ a few opportunistic simplifications to typeck entry point.

Move __thread_local_inner to sys
Move `__thread_local_inner` macro in `crate::thread::local` to `crate::sys`. Initially, I was thinking about removing this macro completely, but I could not find a way to create the generic statics without macros, so in the end, I just moved to code around.
This probably will need a rebase once https://github.com/rust-lang/rust/pull/108917 is merged

rustdoc: Migrate `document_item_info` to Askama
https://rust-lang.zulipchat.com/#narrow/stream/266220-rustdoc/topic/rustdoc.20allocations.20are.20slow
Hoping to piece-by-piece migrate things to template. Had a few failed attempts at more complex parts of the code, so this is just a start.

rustdoc: sort deprecated items lower in search
closes #98759
### Screenshots
`i32::MAX` show sup above `std::i32::MAX` and `core::i32::MAX`
If just searching for `min`, the deprecated results show up far below other things:
one page later
~~And, as you can see, the "Deprecation planned" message shows up in the search results. The same is true for fully-deprecated items like `mem::uninitialized`:
~~
Edit: the deprecation message change was removed from this PR. Only the sorting is changed.

Add more license annotations
This PR updates the `.reuse/dep5` file to include more accurate licensing data for everything in the repository (*excluding* submodules and dependencies). Some decisions were made in this PR:
* The standard copyright attribution for files maintained by us is "The Rust Project Developers (see https://thanks.rust-lang.org)", to avoid having to maintain an in-tree `AUTHORS` file.
* For files that have specific licensing terms, we added the terms to the `.reuse/dep5` rather than adding SPDX comments in the files themselves.
* REUSE picks up any comment/text line with `Copyright` on it, so I had to sprinkle around `REUSE-IgnoreStart` and `REUSE-IgnoreEnd` comments.
The rendered `COPYRIGHT` file is available at https://gist.github.com/pietroalbini/efb81103f69596d39758114f3f6a8688.
