Use `DefId`s instead of `NodeId`s for `pub(restricted)` visibilities
This is groundwork for hygiene 2.0, specifically privacy checking hygienic intercrate name resolutions.

Fix Markdown list formatting.
The Markdown engine used by the book can cope with a single leading space on the list marker:
Like this:
* List item
Rather than like this:
* List item
… but it’s not the typical convention employed in the book, and moreover the Markdown engine used for producing the error index *can’t* cope with it (its behaviour looks like a bug, as it appears to lose one of the two line breaks as well, but that’s immaterial here).
So, we shift to a single convention which doesn’t trigger bugs in the Markdown renderer.

See https://doc.rust-lang.org/error-index.html#E0458 and https://doc.rust-lang.org/error-index.html#E0101 for the bad current rendering in the error index.
Removes magenta build warning.
Small bug fix to remove an unused type in the magenta process code that causes build failures for magenta's rustc.

rustdoc: properly calculate line length for where clauses
Apparently, while I was cleaning up #37190, I regressed the formatting for long where clauses, where it wouldn't take the "prefix" length into account when deciding whether to break the line up. This patch fixes that.
Advertise Vec in LinkedList docs
r? @steveklabnik
Hi! We already [advise](https://doc.rust-lang.org/std/collections/#use-a-linkedlist-when) to use `Vec` instead of `LinkedList` in the top-level collections documentation. But I think it may be missed by someone who just directly finds `LinkedList`.
What do you feel about advertising `Vec` directly in `LinkedList` docs as well?
Simplify notes on testing and concurrency
The start of the notes on tests running concurrently, added in https://github.com/rust-lang/rust/pull/37766 read a little awkwardly. This PR fixes that and simplifies the wording a bit.

std: Fix partial writes in LineWriter
Previously the `LineWriter` could successfully write some bytes but then fail to
report that it has done so. Additionally, an erroneous flush after a successful
write was permanently ignored. This commit fixes these two issues by (a)
maintaining a `need_flush` flag to indicate whether a flush should be the first
operation in `LineWriter::write` and (b) avoiding returning an error once some
bytes have been successfully written.
Closes#37807
Rationale: some ISAs, e.g. OR1K, do not have atomic instructions
for byte and halfword access, and at the same time do not have
a fixed endianness, which makes it unreasonable to implement these
through word-sized atomic accesses.
Prevent where < ident > from parsing.
In order to be forward compatible with `where<'a>` syntax for higher
rank parameters, prevent potential conflicts with UFCS from parsing
correctly for the near term.
Disable field reordering
This was decided via IRC and needs a backport to beta. Basically, #37429 broke servo, and probably needs an announcement and opt-in flag. I didn't run all tests locally but think I've already reverted all the ones that need to be reverted.

Allow legacy custom derive authors to disable warnings in downstream crates
This PR allows legacy custom derive authors to use a pre-deprecated method `registry.register_custom_derive()` instead of `registry.register_syntax_extension()` to avoid downstream deprecation warnings.

Redox Cross Compilation
I will admit - there are things here that I wish I did not have to do. This completes the ability to create a cross compiler from the rust repository for `x86_64-unknown-redox`. I will document this PR with inline comments explaining some things.
[View this gist to see how a cross compiler is built](https://gist.github.com/jackpot51/6680ad973986e84d69c79854249f2b7e)
Prior discussion of a smaller change is here: https://github.com/rust-lang/rust/pull/38366
Refactor global paths
This PR removes the field `global: bool` from `ast::Path` and `hir::Path`, instead representing a global path `::foo::bar` as `{{root}}::foo::bar`, where `{{root}}` is a virtual keyword `keywords::CrateRoot`.
Also, fixes#38016.
