Reexport IntErrorKind in std
Currently `IntErrorKind` can only be found in `core`. @Centril confirmed on Discord that this is unintentional (should I r? him in this situation?).
Should there be a test for this? As far as this *specific* situation goes, I don't think so, I'll risk it and say that there's no way this regresses. However, it might be a good idea to have some tool detect public items in `core` that are not reexported in `std`. Does this belong in tidy, or should that be a separate tool? Is there some rustc-specific *linter*? Unless that's entirely a dumb idea, this should probably get an issue.
Note: My local build hasn't finished yet, but it's well past the point where I would expect problems.
Replace HashMap implementation with SwissTable (as an external crate)
This is the same as #56241 except that it imports `hashbrown` as an external crate instead of copying the implementation into libstd.
This includes a few API changes (all unstable):
- `try_reserve` is added to `HashSet`.
- Some trait bounds have been changed in the `raw_entry` API.
- `search_bucket` has been removed from the `raw_entry` API (doesn't work with SwissTable).
Disallow double trailing newlines in tidy
This wasn't done previously in https://github.com/rust-lang/rust/pull/47064#issuecomment-354533010 as it affected too many files, but I think it's best to fix it now so that the number of files with double trailing newlines doesn't keep increasing.

Fix sync_all on macos/ios
`sync_all` should flush all metadata in macos/ios, so it should call `fcntl` with the `F_FULLFSYNC` flag as `sync_data` does.
Note that without this `sync_data` performs more flushes than `sync_all` on macos/ios.
Remove collection-specific `with_capacity` documentation from `std::collections`
Fixes#59931
The style of `std::collections` module doc is very much a beginner friendly guide, and documenting niche, collection-specific behaviour feels out of place, if not brittle.
The note about `VecDeque` is outdated (see issue), and while `Vec` probably won't change its guarantees any time soon, the users who are interested in its allocation properties will find that in its own documentation.
bump stdsimd; make intra_doc_link_resolution_failure an error again; make lints more consistent
I made `intra_doc_link_resolution_failure` warn so that it would properly respect `deny-warnings = false` in `config.toml`. `#[warn]` still become errors with `-D warnings` so I thought this was fine.
Turns out however that we don't pass `-D warnings` when running rustdoc, so for additional rustdoc-lints we need to set them to `deny`.
Also sue the opportunity to make the lint flags more consistent between libcore, liballoc, libstd.
Cc @gnzlbg for the *big* stdsimd update.
Make BufWriter use get_mut instead of manipulating inner in Write implementation
`get_mut` allows us to abstract over the implementation detail of inner being optional.
std: Add `{read,write}_vectored` for more types
This commit implements the `{read,write}_vectored` methods on more types
in the standard library, namely:
* `std::fs::File`
* `std::process::ChildStd{in,out,err}`
* `std::io::Std{in,out,err}`
* `std::io::Std{in,out,err}Lock`
* `std::io::Std{in,out,err}Raw`
Where supported the OS implementations hook up to native support,
otherwise it falls back to the already-defaulted implementation.
