collect all Fuchsia bindings into the `fuchsia` module

2025-05-05T10:16:40+00:00

The Fuchsia bindings are currently spread out across multiple modules in `sys/pal/unix` leading to unnecessary duplication. This PR moves all of these definitions into `sys::pal::unix::fuchsia` and additionally: * deduplicates the definitions * makes the error names consistent * marks some extern functions as safe * removes unused items (there's no need to maintain these bindings if we're not going to use them) * removes the documentation for the definitions (contributors should always consult the platform documentation, duplicating that here is just an extra maintenance burden)

std: use the address of `errno` to identify threads in `unique_thread_exit` Getting the address of `errno` should be just as cheap as `pthread_self()` and avoids having to use the expensive `Mutex` logic because it always results in a pointer.

Implement a lint for implicit autoref of raw pointer dereference - take 2 *[t-lang nomination comment](https://github.com/rust-lang/rust/pull/123239#issuecomment-2727551097)* This PR aims at implementing a lint for implicit autoref of raw pointer dereference, it is based on #103735 with suggestion and improvements from https://github.com/rust-lang/rust/pull/103735#issuecomment-1370420305. The goal is to catch cases like this, where the user probably doesn't realise it just created a reference. ```rust pub struct Test { data: [u8], } pub fn test_len(t: *const Test) -> usize { unsafe { (*t).data.len() } // this calls <[T]>::len(&self) } ``` Since #103735 already went 2 times through T-lang, where they T-lang ended-up asking for a more restricted version (which is what this PR does), I would prefer this PR to be reviewed first before re-nominating it for T-lang. ---- Compared to the PR it is as based on, this PR adds 3 restrictions on the outer most expression, which must either be: 1. A deref followed by any non-deref place projection (that intermediate deref will typically be auto-inserted) 2. A method call annotated with `#[rustc_no_implicit_refs]`. 3. A deref followed by a `addr_of!` or `addr_of_mut!`. See bottom of post for details. There are several points that are not 100% clear to me when implementing the modifications: - ~~"4. Any number of automatically inserted deref/derefmut calls." I as never able to trigger this. Am I missing something?~~ Fixed - Are "index" and "field" enough? ---- cc `@JakobDegen` `@WaffleLapkin` r? `@RalfJung` try-job: dist-various-1 try-job: dist-various-2

Move `sys::pal::os::Env` into `sys::env` Although `Env` (as `Vars`), `Args`, path functions, and OS constants are publicly exposed via `std::env`, their implementations are each self-contained. Keep them separate in `std::sys` and make a new module, `sys::env`, for `Env`. Also fix `unsafe_op_in_unsafe_fn` for Unix and update the `!DynSend` and `!DynSync` impls which had grown out of sync with the platforms (see #48005 for discussion on that). r? joboet Tracked in #117276.
