Due to a rebase, some edits were needed in the mod file.
- Remove most of the information about passes. Passes are deprecated. - Add `--document-private-items`; it was missing before. - Update `--output-format json`; it was very outdated. - Note that `--input-format` is deprecated. - Move deprecated options to the very end. - Move `passes.html` to the end of the table of contents. Ideally it would be removed altogether, but that causes mdbook not to generate the docs.

resolve: Reduce scope of `pub_use_of_private_extern_crate` deprecation lint This lint was deny-by-default since July 2017, crater showed 7 uses on crates.io back then (rust-lang#42894 (comment)). Unfortunately, the construction `pub use foo as bar` where `foo` is `extern crate foo;` was used by an older version `bitflags`, so turning it into an error causes too many regressions. So, this PR reduces the scope of the lint instead of turning it into a hard error, and only turns some more rarely used components of it into errors.
…ramertj Improved IO Bytes Size Hint After trying to implement better `size_hint()` return values for `File` in [this PR](rust-lang#81044) and changing to implementing it for `BufReader` in [this PR](rust-lang#81052), I have arrived at this implementation that provides tighter bounds for the `Bytes` iterator of various readers including `BufReader`, `Empty`, and `Chain`. Unfortunately, for `BufReader`, the size_hint only improves after calling `fill_buffer` due to it using the contents of the buffer for the hint. Nevertheless, the the tighter bounds should result in better pre-allocation of space to handle the contents of the `Bytes` iterator. Closesrust-lang#81052
… r=GuillaumeGomez Shorten html::render The `mod.rs` for librustdoc's `html::render` was over 3,000 lines. This PR reduces it to around 2,300 by 1. Moving `Context` and associated `impl`s to a separate file 2. Moving the `print_item` function and its helpers to a separate file 3. Moving `write_shared` and `write_minify` to their own file Related to issue rust-lang#60302. Edit 1: `SharedContext` and related `impl`s is only 72 lines and so will not be moved.

Add {BTreeMap,HashMap}::try_insert
`{BTreeMap,HashMap}::insert(key, new_val)` returns `Some(old_val)` if the key was already in the map. It's often useful to assert no duplicate values are inserted.
We experimented with `map.insert(key, val).unwrap_none()` (rust-lang#62633), but decided that that's not the kind of method we'd like to have on `Option`s.
`insert` always succeeds because it replaces the old value if it exists. One could argue that `insert()` is never the right method for panicking on duplicates, since already handles that case by replacing the value, only allowing you to panic after that already happened.
This PR adds a `try_insert` method that instead returns a `Result::Err` when the key already exists. This error contains both the `OccupiedEntry` and the value that was supposed to be inserted. This means that unwrapping that result gives more context:
```rust
map.insert(10, "world").unwrap_none();
// thread 'main' panicked at 'called `Option::unwrap_none()` on a `Some` value: "hello"', src/main.rs:8:29
```
```rust
map.try_insert(10, "world").unwrap();
// thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value:
// OccupiedError { key: 10, old_value: "hello", new_value: "world" }', src/main.rs:6:33
```
It also allows handling the failure in any other way, as you have full access to the `OccupiedEntry` and the value.
`try_insert` returns a reference to the value in case of success, making it an alternative to `.entry(key).or_insert(value)`.

Add assert_matches macro. This adds `assert_matches!(expression, pattern)`. Unlike the other asserts, this one ~~consumes the expression~~ may consume the expression, to be able to match the pattern. (It could add a `&` implicitly, but that's noticable in the pattern, and will make a consuming guard impossible.) See rust-lang#62633 (comment) This re-uses the same `left: .. right: ..` output as the `assert_eq` and `assert_ne` macros, but with the pattern as the right part: assert_eq: ``` assertion failed: `(left == right)` left: `Some("asdf")`, right: `None` ``` assert_matches: ``` assertion failed: `(left matches right)` left: `Ok("asdf")`, right: `Err(_)` ``` cc `@cuviper`
