This commit updates the crate dependency that the standard library has on the `wasi` crate. This is now updated to depending explicitly on the `wasip1` crate and the `wasip2` crate published on crates.io. These crates are managed in the [same location][repo] as the `wasi` crate and represent a different versioning scheme which doesn't require multi-version WASI support to require depending on the same crate at multiple versions. The code in libstd is updated to reference `wasip1` and `wasip2` directly as well. [repo]: https://github.com/bytecodealliance/wasi-rs
This variant was never constructed anywhere.
…ext_chunk, r=Mark-Simulacrum spec next chunk for trustedlen relevant to rust-lang#98326
…imulacrum net::tcp/udp: fix docs about how set_nonblocking is implemented `fcntl` `FIONBIO` doesn't even make sense, it should be `fcntl` `F_SETFL`. However, for some reason we are using `ioctl` by default -- except on Solaris where this doesn't seem to work very well. Honestly what I would have expected is that we just always use `FileDesc::set_nonblocking` also for network sockets, but for some reason we don't and there are no comments explaining this choice.

…lacrum fix: add aliasing rules for Box This is a new revised version for the PR [139857](rust-lang#139857), sorry for the delayed reply. I've rewritten the sentence to closely mirror the wording from `Vec::from_raw_parts`, which clearly states the transfer of ownership and its consequences. This should make the aliasing requirements much clearer. I opted not to include a note about `mem::forget` by default to keep the documentation focused on the primary contract, similar to `Vec`.
…-Simulacrum Make std::fs::File Send on UEFI Similarly to rust-lang#150990 since UEFI has no threads, this should be safe.
…ng, r=Mark-Simulacrum std: fix HashMap RNG docs wording Fixes a wording typo in the top-level HashMap docs. Changed "random number coroutine" to "random number generator" in the seed entropy paragraph. This section is security-relevant, and "generator" is the correct term in RNG context. Testing: - Not run locally (docs-only text change).
Document why `layout.align() + layout.size()` doesn't overflow This addition looks suspicious and is safety critical, but is saved by the weird `Layout` invariants.

Finished benchmarking commit (0febdba): comparison URL. Overall result: ✅ improvements - no action needed@rustbot label: -perf-regression Instruction countOur most reliable metric. Used to determine the overall result above. However, even this metric can be noisy.
Max RSS (memory usage)Results (primary 5.8%)A less reliable metric. May be of interest, but not used to determine the overall result above.
