rustbook: remove dead test functions
There is no "test" subcommand added to the `clap::App`, so this is all dead code.
Cc @steveklabnik -- your [commit](a076961fd0) introducing this stated the intention of having both commands, but it seems nobody has missed the `test` command since February.
impl Debug for SplitWhitespace.
This one got missed because `libstd_unicode` doesn't have a `deny(missing_debug_implementations)` like `libstd` and `libcore`. I think that perhaps this lint should check for items exported from other crates too.
Minor documentation improvements for StmtKind
Documentation for Semi and Marco StmtKinds.
Wasn't obvious to me what these were when writing a lint recently.
update unimplemented! docs
For #42628 (updating docs from changes from #42155).
Initial changes made to make `unimplemented!` doc comments look more like `unreachable!` and remove statement about the panic message.
r? @steveklabnik
use gcc::Build rather than deprecated gcc::Config
I did `cargo update -p gcc` to upgrade only this package. Is there further process that should be follwoed when updating a build dependency from crates.io?

Fixes#43973
rustdoc: add new "Implementations on Foreign Types" section to traits
Demo screenshot:
Full demo available at https://tonberry.quietmisdreavus.net/foreign-test/foreign_test/trait.CheckIt.html
This PR splits the "Implementors" section on trait pages into two: First, for impls on types local to the crate, their impls are kept as-is, printing one line for the impl line, and any additional lines for associated types. However, for types external to the crate, they are now pulled up over the others and are printed (almost) like the summary impl on the type page itself. This gives any doc comments on these impls or methods to be exposed in the documentation.
There's just one small problem, though: [libstd docs apparently surface impls for libc and rand, possibly among others](https://tonberry.quietmisdreavus.net/foreign-std/std/marker/trait.Copy.html#foreign-impls). This adds this section to pages in the std docs where we might not want them to show up in the first place. I think this is a bug distinct from this PR, but it does make it drastically apparent.
~~My question, then, is this: Do we want this here? Taking it out involves fixing which impls are visible to rustdoc, possibly specifically when rendering the std facade. I'm convinced this is fine to land as-is, since it adds a feature specifically for non-std crates (i'm thinking of things like `num` or related crates that implement things on primitives or std types as part of their functionality).~~ (EDIT: I have an open PR to fix this: https://github.com/rust-lang/rust/pull/44026)
At the moment it is always missing for Cargo and RLS.
Their respective build systems need to be modified to include
`git-commit-hash` files in their "dist" tarballs.
Compact display of static lib dependencies
Fixes#33173
Instead of displaying one dependency per line, I've changed the format to display them all in one line.
As a bonus they're in format of linker flags (`-lfoo`), so the output can be copy&pasted if one is actually going to link as suggested.
expand on using rustup custom toolchains in CONTRIBUTING.md
fixes#42484
Should i include more notes about how to use a local build *without* rustup? It can kinda feel like a cop-out otherwise. Other means that come to mind are setting `$RUSTC` directly and fully installing it.
