… indexing

The error can be quite confusing to newcomers.

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.

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.

Extra documentation for new formatting feature

Documentation of this feature was added in rust-lang#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.

I'm not so sure about the message, open to wording suggestions.

Diagnose missing includes in run-make tests

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.

Rewrite error index generator to greatly reduce the size of the pages

Fixes rust-lang#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 `--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.
