Small fixes in rustdoc book
I read the `rustdoc` book today and noticed some small typos/problems. Mainly:
- `# fn foo() {}` was displayed when not needed because fenced block code type was `text` instead of `rust`;
- two path separators were missing and some Windows-style separators were not consistent with the rest of them (mainly Linux-style).
Here are my proposed fixes. It is my first PR for the rust project. Don't hesitate to tell me if I am doing it wrong or if you need anything else.
Have a nice day!
Block version-specific docs from search engines
Latest stable, beta and nightly URLs remain accessible because their URLs don't start with a version number. Robots.txt uses simple path prefixes, so it's OK that the disallow rules aren't full directory paths.
Direct links to old docs remain accessible to users, because robots.txt only affects crawlers.
With this change old docs for specific old versions of Rust won't pop up in search results. This is good, because users won't be getting obsolete documentation by accident.
Use `pprust` to print attributes in rustdoc
Fixes https://github.com/rust-lang/rust/issues/69559.
I'm not sure what the original motivation was for the `render_attribute`, so I may be missing something, but replacing it with `pprust::attribute_to_string` seems to give the intended output (modulo some spacing idiosyncrasies).

Fix "since" field for `Once::is_complete`'s `#[stable]` attribute
It was accidentally merged with the wrong version in #68945. Thanks @jplatte for noticing.
This also needs to be beta backported.
Return feature gate as a `Symbol`
A minor refactoring that will be needed for #68940. That PR is blocked on me changing the error comments in a whole lot of UI tests.

def_collector: Fully visit async functions
We forgot to visit attributes previously, it caused ICEs.
Special treatment of async functions is also moved from `visit_item` to `visit_fn` to reuse more of the default visitor.
Fixes https://github.com/rust-lang/rust/issues/67778.
Implement From<&mut str> for String
I ran into this missing impl when trying to do `String::from` on the result returned from this API in the `uuid` crate:
https://docs.rs/uuid/0.8.1/uuid/adapter/struct.Hyphenated.html#method.encode_lower
I wasn't sure what to put in the stability annotation. I'd appreciate some help with that :)
ast: `Mac`/`Macro` -> `MacCall`
It's now obvious that these refer to macro calls rather than to macro definitions.
It's also a single name instead of two different names in different places.
`rustc_expand` usually calls macro calls in a wide sense (including attributes and derives) "macro invocations", but structures and variants renamed in this PR are only relevant to fn-like macros, so it's simpler and clearer to just call them calls.

Add undo_leak to reset RefCell borrow state
This method is complementary for the feature cell_leak added in an
earlier PR. It allows *safely* reverting the effects of leaking a borrow guard by
statically proving that such a guard could not longer exist. This was
not added to the existing `get_mut` out of concern of impacting the
complexity of the otherwise pure pointer cast and because the name
`get_mut` poorly communicates the intent of resetting remaining borrows.
This is a follow-up to #68712 and uses the same tracking issue, #69099,
as these methods deal with the same mechanism and the idea came up
[in a review comment](https://github.com/rust-lang/rust/pull/68712#discussion_r384670041).

Change "method" to "associated function"
r? @matthewjasper
cc @Centril @eddyb #67742
I'm opening this mostly as a test to see what the diagnostic changes would be. It seems that this makes them somewhat more verbose, and I'm not sure it's worth it...
The relevant changes are the last two commits (it is rebased on top of #67742)
Remove `sip::Hasher::short_write`.
`sip::Hasher::short_write` is currently unused. It is called by
`sip::Hasher::write_{u8,usize}`, but those methods are also unused,
because `DefaultHasher`, `SipHasher` and `SipHasher13` don't implement
any of the `write_xyz` methods, so all their write operations end up
calling `sip::Hasher::write`.
(I confirmed this by inserting a `panic!` in `sip::Hasher::short_write`
and running the tests -- they all passed.)
The alternative would be to add all the missing `write_xyz` methods.
This does give some significant speed-ups, but it hurts compile times a
little in some cases. See #69152 for details. This commit does the
conservative thing and doesn't change existing behaviour.

Emit 1-based column numbers in debuginfo
* Use byte offsets instead of char position offsets. Resolves#67360.
* Use 1-based offsets instead of 0-based ones. Resolves#65437.
* Consistently omit column information for msvc targets, matching clang behaviour (previously columns have been omitted from `DILocation`, but not from `DILexicalBlock`).
