a40d79c9fb Rollup merge of #76993 - blitzerr:alloc-ref, r=Amanieu 
Changing the alloc() to accept &self instead of &mut self

Fixes: [#55](https://github.com/rust-lang/wg-allocators/issues/55)

This is the first cut. It only makes the change for `alloc` method.

50d3ddcb0c make ln_1p examples more representative of use 
With this commit, the examples for ln_1p would fail if (x + 1.0).ln()
is used instead of x.ln_1p().

110e59e70e Update library functions with stability attributes 
This may not be strictly minimal, but all unstable functions also need a
`rustc_const_unstable` attribute.

e0bc267512 Auto merge of #76110 - FedericoPonzi:convert-openoptions-cint, r=JoshTriplett 
Function to convert OpenOptions to c_int

Fixes: #74943
The creation_mode and access_mode function were already available in the OpenOptions struct, but currently private. I've added a new free functions to unix/fs.rs which takes the OpenOptions, and returns the c_int to be used as parameter for the `open` call.

ae4b677aa8 Rollup merge of #76521 - tavianator:fix-pthread-getattr-destroy, r=Amanieu 
Fix segfault if pthread_getattr_np fails

glibc [destroys][1] the passed pthread_attr_t if pthread_getattr_np()
fails.  Destroying it again leads to a segfault.  Fix it by only
destroying it on success for glibc.

b670b86353 Rollup merge of #76936 - danielhenrymantilla:unsafecell_get_mut, r=RalfJung 
Add non-`unsafe` `.get_mut()` for `Unsafecell`

  - Tracking issue: https://github.com/rust-lang/rust/issues/76943

As discussed in: https://internals.rust-lang.org/t/add-non-unsafe-get-mut-for-unsafecell/12407

  - ### [Rendered documentation](https://modest-dubinsky-1f9f47.netlify.app/core/cell/struct.unsafecell)

This PR tries to move the sound `&mut UnsafeCell<T> -> &mut T` projection that all the "downstream" constructions were already relying on, up to the root abstraction, where it rightfully belongs, and officially blessing it.

  - this **helps reduce the amount of `unsafe` snippets out there** (_c.f._, the second commit of this PR: 09503fd1b3)

The fact that this getter is now expose for `UnsafeCell<T>` itself, will also help convey the idea that **`UnsafeCell` is not magical _w.r.t._ `&mut` accesses**, contrary to what some people incorrectly think.

  - Even the standard library itself at some point had such a confusion, _c.f._ this comment where there is a mention of multi-threaded (and thus _shared_) access despite dealing with exclusive references over unique ownership: 59fb88d061/library/core/src/cell.rs (L498-L499)

Remove unused feature gates from library/ crates

Removes some unused feature gates from library crates. It's likely not a complete list as I only tested a subset for which it's more likely that it is unused.
