Do not ping the infrastructure team on toolstate changes
To my knowledge, there is essentially never any particular action that the infra team needs to take on these pings, and they are currently relatively annoying.
cc rust-lang/infra -- does anyone *want* these notifications?

Add shared script for linkchecking books.
This adds a script that can be used on each book's CI to ensure they don't break local links.
I've been running something similar on the reference CI. The intent here is to add this to all the external books' CI scripts. This will help avoid dealing with broken links when updating submodules on rust-lang/rust.

rustc_session: allow overriding lint level of individual lints from a group
Fixes#58211 and fixesrust-lang/rust-clippy#4778 and fixesrust-lang/rust-clippy#4091
Instead of hard-coding the lint level preferences (from lowest to highest precedence: `lint::Allow -> lint::Warn -> lint::Deny -> lint::Forbid`), the position of the argument in the command line gets taken into account.
Examples:
1. Passing `-D unused -A unused-variables` denies everything in the lint group `unused` **except** `unused-variables` which is explicitly allowed.
1. Passing `-A unused-variables -D unused` denies everything in the lint group `unused` **including** `unused-variables` since the allow is specified before the deny (and therefore overridden by the deny).
This matches the behavior that is already being used when specifying `allow`/`deny` in the source code.
Update books.
This required some changes in how the books are tested due to some changes in rust-lang/book. It uses new syntax that is not compatible with bare `rustdoc --test`. This changes it so that it uses rustbook to run the tests, which is essentially the same as `mdbook test`.

Use termize instead of term_size
