rust: library: Add `setsid` method to `CommandExt` trait
Add a setsid method to the CommandExt trait so that callers can create a process in a new session and process group whilst still using the POSIX spawn fast path.
Tracking issue: rust-lang/rust#105376
ACP: https://github.com/rust-lang/libs-team/issues/184
This PR was previously submitted by ``@HarveyHunt`` (whom I marked as Co-Author in the commit message) in rust-lang/rust#105377. However that PR went stale.
I applied the [suggestion](https://github.com/rust-lang/rust/pull/105377/files/231d19fcbfe155b2e85116865adae4253380ff1f#r1893457943) to change the function signature to `fn setsid(&mut self, setsid: bool) -> &mut Command`.

Set MSG_NOSIGNAL for UnixStream
https://github.com/rust-lang/rust/issues/139956
Same logic as for https://github.com/rust-lang/rust/blob/1f76d219c906f0112bb1872f33aa977164c53fa6/library/std/src/sys/net/connection/socket.rs#L399-L405.

Implement send_signal for unix child processes
Tracking issue: rust-lang/rust#141975
There are two main differences between my implementation and the Public API section of the tracking issue. ~First, `send_signal` requires a mutable reference, like `Child::kill`.~ Second, `ChildExt` has `Sealed` as a supertrait, bringing it more in line with other extension traits like `CommandExt`.

This allows UTF-8 characters to be printed without escapes, rather than
just ASCII.

process
This adds a `chroot` method to the `CommandExt` extension trait for the
`Command` builder, to set a directory to chroot into. This will chroot
the child process into that directory right before calling chdir for the
`Command`'s working directory.
To avoid allowing a process to have a working directory outside of the
chroot, if the `Command` does not yet have a working directory set,
`chroot` will set its working directory to "/".

Use `std::mem::{size_of, size_of_val, align_of, align_of_val}` from the
prelude instead of importing or qualifying them.
These functions were added to all preludes in Rust 1.80.

Expand std::os::unix::fs::chown() doc with a warning
Include warning about losing setuid/gid when chowning, per POSIX.
It is about the underlying system call but it is rather useful to mention it in the help in case someone accidentally forgets (don't look at me :)).

Make `std::os::darwin` public
I'm not sure of the reasoning behind them not being public before, but I think they should be, just like `std::os::ios` and `std::os::macos` are public.
Additionally, I've merged their source code, as it was otherwise just a bunch of unnecessary duplication.
Ultimately, I've done this PR to fix `./x build library --target=aarch64-apple-tvos,aarch64-apple-watchos,aarch64-apple-visionos`, as that currently fails because of dead code warnings.

Use `mem::offset_of!` for `sockaddr_un.sun_path`
We don't need manual pointer math here anymore!
try-job: dist-i686-msvc

Since the stabilization in #127679 has reached stage0, 1.82-beta, we can
start using `&raw` freely, and even the soft-deprecated `ptr::addr_of!`
and `ptr::addr_of_mut!` can stop allowing the unstable feature.
I intentionally did not change any documentation or tests, but the rest
of those macro uses are all now using `&raw const` or `&raw mut` in the
standard library.

This includes `std::os::darwin::fs`, which is re-exported under
`std::os::macos::fs` and `std::os::ios::fs`.
`std::os::darwin::raw` is not exposed, which means that
`MetadataExt::as_raw_stat` isn't available on tvOS, visionOS and
watchOS.

The previous commit updated `rustfmt.toml` appropriately. This commit is
the outcome of running `x fmt --all` with the new formatting options.

Fix doc nits
Many tiny changes to stdlib doc comments to make them consistent (for example "Returns foo", rather than "Return foo"), adding missing periods, paragraph breaks, backticks for monospace style, and other minor nits.

Both these platforms have MSG_NOSIGNAL available, and we should set it for
socket writes in the event that the SIGPIPE handler has been reset to SIG_DFL
(i.e. terminate the process).
I've verified via a quick program at
https://github.com/sunshowers/msg-nosignal-test/ that even when the SIGPIPE
handler is reset to SIG_DFL, writes to closed sockets now error out with EPIPE.
(Under ordinary circumstances UDP writes won't cause MSG_NOSIGNAL.)

Fix build failure on vxworks #127084
PR to address issue #127084 .
1. Skip `reset_segpipe` for vxworks
2. Return unimplemented error for vxworks from settimes and lchown
3. Temporarily skip dirfd for vxworks
4. Add allow unused unsafe on read_at and write_at functions in unix/fs.rs
5. Using cfg disable ON_BROKEN_PIPE_FLAG_USED and on_broken_pipe_flag_used() for vxworks
6. Remove old crate::syscommon::thread::min_stack() reference from process_vxworks.rs and update to set stack size of rtpthread
Thank you.
