Add a missing test case for impl generic mismatch
This suggestion use different span depending on whether the method has generics or not, so I added a test case about the method with some generics.
rustdoc: remove unused CSS rule
According to [blame], this rule was added to support enum struct variants. However, enum struct variants don't use tables in their design any more, so this rule does nothing.

Use `--userns=keep-id` when "docker" is really podman
Rootless podman creates a separate user namespace, where an inner
`LOCAL_USER_ID` will map to a different subuid range on the host.
The "keep-id" mode maps the current UID directly into the container.
This makes `src/ci/docker/run.sh` work better for testing container
images on systems running podman, where "docker" is just a shim.
Rewrite error index generator to greatly reduce the size of the pages
Fixes https://github.com/rust-lang/rust/issues/100736.
Instead of having all error codes in a same page (making the DOM way too big), I split the output into multiple files and generated a list of links (if there is an explanation) to the error codes' explanation into the already existing file.
I also used this opportunity to greatly simplify the code. Instead of needing a `build.rs`, I simply imported the file we want and wrote the macro which generates a function containing everything we need. We just need to call it to get the error codes and their explanation (if any). Also, considering the implementations between markdown and HTML formats differed even further, the `Formatter` trait was becoming too problematic so I removed it too.
You can test it [here](https://rustdoc.crud.net/imperio/rewrite-error-index/error-index.html).

Use par_body_owners for liveness
I did this refactoring while working on something else. Liveness is about bodies, there is no reason to use par_for_each_module here.
Tests are updated because things are visited in a different order. I checked diagnostics are same, just in a different (and IMO, better) order.
Suggest alternatives when trying to mutate a `HashMap`/`BTreeMap` via indexing
The error can be quite confusing to newcomers.
Fixes#100873.
I'm not so sure about the message, open to wording suggestions.
Coherence negative impls implied bounds

This PR is rebased on top of #100789 and it would need to include that one which is already r+ed.

Extra documentation for new formatting feature
Documentation of this feature was added in #90473 and released in Rust 1.58. However, high traffic macros did not receive new examples. Namely `println!()` and `format!()`.
The doc comments included in Rust are super important to the community- especially newcomers. I have met several other newbies like myself who are unaware of this recent (well about 7 months old now) update to the language allowing for convenient intra-string identifiers.
Bringing small examples of this feature to the doc comments of `println!()` and `format!()` would be helpful to everyone learning the language.

sugg: take into count the debug formatting
Closes https://github.com/rust-lang/rust/issues/100648
This PR will fix a suggestion error by taking into consideration also the `:?` symbol and act in a different way

N.B: I did not find a full way to test the change, any idea?
- Disallow multiple macros callbacks in the same invocation. In practice, this was never used.
- Remove the `[]` brackets around the macro name
- Require an `ident`, not an arbitrary `tt`

- Warning when precise or aggressive without -p flag (rust-lang/cargo#10988)
This should both make the code easier to read and also greatly reduce the amount of codegen
the compiler has to do, since it only needs to monomorphize `create_query_frame` for each
new key and not for each query.
Rustdoc documents these with the name of the type alias instead of normalizing them to the underlying type.
Use associated types instead so that the generated docs for nightly-rustc are easier to read.
Optimize `Wtf8Buf::into_string` for the case where it contains UTF-8.
Add a `is_known_utf8` flag to `Wtf8Buf`, which tracks whether the
string is known to contain UTF-8. This is efficiently computed in many
common situations, such as when a `Wtf8Buf` is constructed from a `String`
or `&str`, or with `Wtf8Buf::from_wide` which is already doing UTF-16
decoding and already checking for surrogates.
This makes `OsString::into_string` O(1) rather than O(N) on Windows in
common cases.
And, it eliminates the need to scan through the string for surrogates in
`Args::next` and `Vars::next`, because the strings are already being
translated with `Wtf8Buf::from_wide`.
Many things on Windows construct `OsString`s with `Wtf8Buf::from_wide`,
such as `DirEntry::file_name` and `fs::read_link`, so with this patch,
users of those functions can subsequently call `.into_string()` without
paying for an extra scan through the string for surrogates.

fluent: mandate slug names to be prefixed by crate name
This is currently only convention, but not actively checked for.
Additionally, improve error messages to highlight the path of the offending fluent file rather than the identifier preceding it.
This will conflict with #100671, so I'll leave it as draft until that's merged.
