5176f677f5 slice: Stabilize IterMut::as_slice. 
Much like #72584.

As per #58957 there's no blocker for this, and I wanted to use this
today :-)

84e9608596 Fix leak in Vec::extend_from_within 
Previously vec's len was updated only after full copy, making the method
leak if T::clone panic!s.

This commit makes `Vec::extend_from_within` (or, more accurately, it's
`T: Clone` specialization) update vec's len on every iteration, fixing
the issue.

`T: Copy` specialization was not affected by the issue b/c it doesn't
call user specified code (as, e.g. `T::clone`), and instead calls
`ptr::copy_nonoverlapping`.

I strongly disagree with tidy in this case but AIUI there is no way to
override it.

a240ff5a77 ExitStatus unknown wait status test: Make it Linux only 
If different unices have different bit patterns for WIFSTOPPED and
WIFCONTINUED then simply being glibc is probably not good enough for
this rather ad-hoc test to work.  Do it on Linux only.

290117f7d9 Rollup merge of #82564 - WaffleLapkin:revert_spare_mut, r=RalfJung 
Revert `Vec::spare_capacity_mut` impl to prevent pointers invalidation

The implementation was changed in #79015.

Later it was [pointed out](https://github.com/rust-lang/rust/issues/81944#issuecomment-782849785) that the implementation invalidates pointers to the buffer (initialized elements) by creating a unique reference to the buffer. This PR reverts the implementation.

f898aa3f5b Rollup merge of #80527 - jyn514:rustdoc-lints, r=GuillaumeGomez 
Make rustdoc lints a tool lint instead of built-in

- Rename `broken_intra_doc_links` to `rustdoc::broken_intra_doc_links` (and similar for other rustdoc lints; I don't expect any others to be used frequently, though).
- Ensure that the old lint names still work and give deprecation errors
- Register lints even when running doctests
- Move lint machinery into a separate file
- Add `declare_rustdoc_lint!` macro

Unblocks https://github.com/rust-lang/rust/pull/80300, https://github.com/rust-lang/rust/pull/79816, https://github.com/rust-lang/rust/pull/80965. Makes the strangeness in https://github.com/rust-lang/rust/pull/77364 more apparent to the end user (note that `missing_docs` is *not* moved to rustdoc in this PR). Closes https://github.com/rust-lang/rust/issues/78786.

`redox` and `vxworks` are now part of target_family `unix`, thus `cfg(unix)` already implies `cfg(target_os="redox")` and `cfg(target_os="vxworks")`

cbca5689a5 Auto merge of #76345 - okready:sgx-mem-range-overflow-checks, r=joshtriplett 
Add is_enclave_range/is_user_range overflow checks

Fixes #76343.

This adds overflow checking to `is_enclave_range` and `is_user_range` in `sgx::os::fortanix_sgx::mem` in order to mitigate possible security issues with enclave code. It also accounts for an edge case where the memory range provided ends exactly at the end of the address space, where calculating `p + len` would overflow back to zero despite the range potentially being valid.
