Fix crash in BufReader::peek()
`bufreader_peek` tracking issue: #128405
This fixes a logic error in `Buffer::read_more()` that would make `BufReader::peek()` expose uninitialized data and/or segfault if `read_more()` was called with a partially-full buffer and a non-empty inner reader.
Specialize `OsString::push` and `OsString as From` for UTF-8
When concatenating two WTF-8 strings, surrogate pairs at the boundaries need to be joined. However, since UTF-8 strings cannot contain surrogate halves, this check can be skipped when one string is UTF-8. Specialize `OsString::push` to use a more efficient concatenation in this case.
The WTF-8 version of `OsString` tracks whether it is known to be valid UTF-8 with its `is_known_utf8` field. Specialize `From<AsRef<OsStr>>` so this can be set for UTF-8 string types.
Unfortunately, a specialization for `T: AsRef<str>` conflicts with `T: AsRef<OsStr>`, so stamp out string types with a macro.

Override default `Write` methods for cursor-like types
Override the default `io::Write` methods for cursor-like types to provide more efficient versions.

# Open questions
Is it guaranteed by `Write::write_all` that the maximal write is performed when not everything can be written? Its documentation describes the behavior of the default implementation, which writes until a 0-length write is encountered, thus implying that a maximal write is expected. In contrast, `Read::read_exact` declares that the contents of the buffer are unspecified for short reads. If it were allowed, these cursor-like types could bail on the write altogether if it has insufficient capacity.
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.

[illumos] attempt to use posix_spawn to spawn processes
illumos has `posix_spawn`, and the very newest versions also have `_addchdir`, so use that. POSIX standardized this function so I also added a weak symbol lookup for the non `_np` version. (illumos has both.)
This probably also works on Solaris, but I don't have access to an installation to validate this so I decided to focus on illumos instead.

Use correct error message casing for `io::const_error`s
Error messages are supposed to start with lowercase letters, but a lot of `io::const_error` messages did not. This fixes them to start with a lowercase letter.
I did consider adding a const check for this to the macro, but some of them start with proper nouns that make sense to uppercase them.
See https://doc.rust-lang.org/1.85.0/std/error/trait.Error.html
Buffer::read_more() is supposed to refill the buffer without discarding
its contents, which are in the range `pos .. filled`.
It mistakenly borrows the range `pos ..`, fills that, and then
increments `filled` by the amount read. This overwrites the buffer's
existing contents and sets `filled` to a too-large value that either
exposes uninitialized bytes or walks off the end of the buffer entirely.
This patch makes it correctly fill only the unfilled portion of the
buffer, which should maintain all the type invariants and fix the test
failure introduced in commit b1196717fc.
This patch makes BufReader::peek()'s doctest call read_more() to refill
the buffer before the inner reader hits EOF. This exposes a bug in
read_more() that causes an out-of-bounds slice access and segfault.

Fix Windows `Command` search path bug
Currently `Command::new` on Windows works differently depending on whether any environment variable is set. For example,
```rust
// Searches for "myapp" in the application and system paths first (aka Windows native behaviour).
Command::new("myapp").spawn();
// Search for "myapp" in `PATH` first
Command::new("myapp").env("a", "b").spawn();
```
This is a bug because the search path should only change if `PATH` is changed for the child (i.e. `.env("PATH", "...")`).
This was discussed in a libs-api meeting where the exact semantics of `Command::new` was not decided but there seemed to be broad agreement that this particular thing is just a bug that can be fixed.

The recent fixes to private dependencies exposed some cases in the UEFI
module where private dependencies are exposed in a public interface.
These do not need to be crate-public, so change them to `pub(crate)`.
For the zkVM, even when a guest buffer is uninitialized, from the host's
perspective it is just a normal piece of memory which was initialized
before letting the guest write into it. This makes `sys_read` safe to

Organize `OsString`/`OsStr` shims
Synchronize the `bytes.rs` and `wtf8.rs` shims for `OsString`/`OsStr` so they're easier to diff between each other. This is mostly ordering items the same between the two. I tried to minimize moves and went for the average locations between the files.
With them in the same order, it is clear that `FromInner<_>` is not implemented for `bytes::Buf` and `Clone::clone_from` is not implemented for `wtf8::Buf`, but they are for the other. Fix that.
I added #[inline] to all inherent methods of the `OsString`/`OsStr` shims, because it seemed that was already the rough pattern. `bytes.rs` has more inlining than `wtf8.rs`, so I added the corresponding ones to `wtf8.rs`. Then, the common missing ones have no discernible pattern to me. They're not divided by non-allocating/allocating. Perhaps the pattern is that UTF-8 validation isn't inlined? Since these types are merely the inner values in `OsStr`/`OsString`, I put inline on all methods and let those public types dictate inlining. I have not inspected codegen or run benchmarks.
Also, touch up some (private) documentation comments.

Add a bullet point to `std::fs::copy`
I needed to copy a file but I got the following error:

Use `tell` for `<File as Seek>::stream_position`
Some platforms have a more efficient way to get the current offset of the file than by seeking. For example, Wasi has `fd_tell` and SOLID has `SOLID_FS_Ftell`. Implement `<File as Seek>::stream_position()` in terms of those.
I do not use any APIs that were not already used in `std`. Although, the `libc` crate has [`ftell`](https://docs.rs/libc/latest/libc/fn.ftell.html), [`ftello`](https://docs.rs/libc/latest/libc/fn.ftello.html), and [`ftello64`](https://docs.rs/libc/latest/libc/fn.ftello64.html), I do not know platform coverage. It appears that Windows has no `tell`-like API.

Windows: Update generated bindings
Update to windows-bindgen 0.59.
This update is aimed at reducing churn in the future, but means a bit more churn now:
- `bindings.txt` no longer needs us to write the namespace for each item. This is good because it means in the future we won't need to change them if the namespace changes. However, there are a few where we still need to disambiguate due to duplicate items (this is a bug in the upstream metadata).
- The output in `windows-sys.rs` is now sorted. It was mostly sorted before but not intentionally. This should mean future changes are less noisy.
The actual code changes are minimal here. A few types are now `bool` instead of `BOOLEAN`, which is more convenient.

- Makes the different edition preludes consistent, and sets a pattern that can be used by future editions.

std: replace the `FromInner` implementation for addresses with private conversion functions
Having these implementation available crate-wide means that platforms not using sockets for their networking code have to stub out the libc definitions required to support them. This PR moves the conversions to private helper functions that are only available where actually needed.
I also fixed the signature of the function converting from a C socket address to a Rust one: taking a reference to a `sockaddr_storage` resulted in unsound usage inside `LookupHost::next`, which could create a reference to a structure smaller than `sockaddr_storage`. Thus I've replaced the argument type with a pointer and made the function `unsafe`.

Update docs for impl keyword
This started as a fix for #79878, but also introduces some structure (headings), and elaborates a tiny bit on impl Trait syntax.
Improve examples for file locking
The `lock` and `try_lock` documentation states that "if the file not open for writing, it is unspecified whether this function returns an error." With this change, the examples use `File::create` instead of `File::open`, eliminating the possibility of someone blindly copying code with unspecified behavior.
rustfmt fails to format this match expression, because it has several
long string literals over the maximum line width. This seems to exhibit
rustfmt issues #3863 (Gives up on chains if any line is too long) and
#3156 (Fail to format match arm when other arm has long line).
Some miscellaneous edition-related library tweaks
Some library edition tweaks that can be done separately from upgrading the whole standard library to edition 2024 (which is blocked on getting the submodules upgraded, for example)
Use an `Option` for `FindNextFileHandle` in `ReadDir` instead of `INVALID_FILE_HANDLE` sentinel value
Sometimes we store an invalid handle when we don't want to return an error. We then check the handle before use in order to avoid actually using the invalid handle. However, using an `Option` for this is better and avoids us forgetting to check the handle is valid. This was noticed due to us closing the handle without checking for validity: bd6a6777f5/library/std/src/sys/pal/windows/fs.rs (L148-L151)
Update bootstrap compiler and rustfmt
The rustfmt version we previously used formats things differently from what the latest nightly rustfmt does. This causes issues for subtrees that get formatted both in-tree and in their own repo. Updating the rustfmt used in-tree solves those issues. Also bumped the bootstrap compiler as the stage0 update command always updates both at the same
time.

Closes#136633.
[^1]: At the time of writing.
sys: net: Add UEFI stubs
- Just a copy of sys/net/unsupported.
- Will make the future net PRs easier to review.
- The reason for a separate folder instead of standalone file is that UEFI has separate the protocols for v4 and v6, and thus will need some abstractions to implement the Rust interface.

This was never modified since `std::net` was originally introduced, when
each CI job was running multiple jobs concurrently which caused issues
with fighting over the same ports. This is not the case in the current
CI infrastructure, so remove this relic.
std: move network code into `sys`
As per #117276, this PR moves `sys_common::net` and the `sys::pal::net` into the newly created `sys::net` module. In order to support #135141, I've moved all the current network code into a separate `connection` module, future functions like `hostname` can live in separate modules.
I'll probably do a follow-up PR and clean up some of the actual code, this is mostly just a reorganization.
uefi: process: Add support for command environment variables
Set environment variables before launching the process and restore the prior variables after the program exists.
This is the same implementation as the one used by UEFI Shell Execute [0].

Implement unstable `new_range` feature
Switches `a..b`, `a..`, and `a..=b` to resolve to the new range types.
For rust-lang/rfcs#3550
Tracking issue #123741
also adds the re-export that was missed in the original implementation of `new_range_api`
Move some std tests to integration tests
Unit tests directly inside of standard library crates require a very fragile way of building that is hard to reproduce outside of bootstrap.

docs: Documented Send and Sync requirements for Mutex + MutexGuard
This an attempt to continue where #123225 left off.
I did some light clean up from the work done in that PR.
I also documented the `!Send` + `Sync` implementations for `MutexGuard` to the best of my knowledge.
Let me know if I got anything wrong 😄fixes#122856
