Move the Windows remove_dir_all impl into a module and make it more race resistant
This attempts to make the Windows implementation of `remove_dir_all` easier to understand and work with by separating out different concerns into their own functions. The code is mostly the same as before just moved around. There are some changes to make it more robust against races (e.g. two calls to `remove_dir_all` running concurrently). The module level comment explains the issue.

Fix compile error in solid's remove_dir_all
Before this PR, `x check library/std --target=aarch64-kmc-solid_asp3` will fail with:

Apply size optimizations to panic machinery and some cold functions
* std dependencies gimli and addr2line are now built with opt-level=s
* various panic-related methods and `#[cold]` methods are now marked `#[optimize(size)]`
Panics should be cold enough that it doesn't make sense to optimize them for speed. The only tradeoff here is if someone does a lot of backtrace captures (without panics) and printing then the opt-level change might impact their perf.
Seems to be the first use of the optimize attribute. Tracking issue #54882

add `aarch64_unknown_nto_qnx700` target - QNX 7.0 support for aarch64le
This backports the QNX 7.1 aarch64 implementation to 7.0.
* [x] required `-lregex` disabled, see https://github.com/rust-lang/libc/pull/3775 (released in libc 0.2.156)
* [x] uses `libgcc.a` instead of `libgcc_s.so` (7.0 used ancient GCC 5.4 which didn't have gcc_s)
* [x] a fix in `backtrace` crate to support stack traces https://github.com/rust-lang/backtrace-rs/pull/648
This PR bumps libc dependency to 0.2.158

# Configure a remote for testing
Do this from a new shell - we will need to run more commands in the previous one. I ran into these two issues, and found some workarounds.
* Temporary dir might not work properly
* Default `remote-test-server` has issues binding to an address
```
# ./remote-test-server
starting test server
thread 'main' panicked at src/tools/remote-test-server/src/main.rs:175:29:

Specifying `--bind` param actually fixes that, and so does setting `TMPDIR` properly.

wasi: Fix sleeping for `Duration::MAX`
This commit fixes an assert in the WASI-specific implementation of thread sleep to ensure that sleeping for a very large period of time blocks instead of panicking. This can come up when testing programs that sleep "forever", for example.
I'll note that I haven't included a test for this since it's sort of difficult to test. I've tested this locally though that long sleeps do indeed block and short sleeps still only sleep for a short amount of time.

copysign with sign being a NaN can have non-portable results
Follow-up to https://github.com/rust-lang/rust/pull/129559.
Cc ```@tgross35``` ```@beetrees```
There's no portable variant we can recommend instead here, is there? Something with a semantics like "if `sign` is a NaN, then return `self` unaltered, otherwise return `self` with the sign changed to that of `sign`"?

Partially stabilize `feature(new_uninit)`
Finished comment period: https://github.com/rust-lang/rust/issues/63291#issuecomment-2183022955
The following API has been stabilized from https://github.com/rust-lang/rust/issues/63291
```rust
impl<T> Box<T> { pub fn new_uninit() -> Box<MaybeUninit<T>> {…} }
impl<T> Rc<T> { pub fn new_uninit() -> Rc<MaybeUninit<T>> {…} }
impl<T> Arc<T> { pub fn new_uninit() -> Arc<MaybeUninit<T>> {…} }
impl<T> Box<[T]> { pub fn new_uninit_slice(len: usize) -> Box<[MaybeUninit<T>]> {…} }
impl<T> Rc<[T]> { pub fn new_uninit_slice(len: usize) -> Rc<[MaybeUninit<T>]> {…} }
impl<T> Arc<[T]> { pub fn new_uninit_slice(len: usize) -> Arc<[MaybeUninit<T>]> {…} }
impl<T> Box<MaybeUninit<T>> { pub unsafe fn assume_init(self) -> Box<T> {…} }
impl<T> Box<[MaybeUninit<T>]> { pub unsafe fn assume_init(self) -> Box<[T]> {…} }
impl<T> Rc<MaybeUninit<T>> { pub unsafe fn assume_init(self) -> Rc<T> {…} }
impl<T> Rc<[MaybeUninit<T>]> { pub unsafe fn assume_init(self) -> Rc<[T]> {…} }
impl<T> Arc<MaybeUninit<T>> { pub unsafe fn assume_init(self) -> Arc<T> {…} }
impl<T> Arc<[MaybeUninit<T>]> { pub unsafe fn assume_init(self) -> Arc<[T]> {…} }
```
The remaining API is split between new issues
- `new_zeroed_alloc`: https://github.com/rust-lang/rust/issues/129396
- `box_uninit_write`: https://github.com/rust-lang/rust/issues/129397
All relevant code is thus either stabilized or split out of that issue, so this closes #63291 as, with the FCP concluded, that issue has served its purpose.

Clean up cfg-gating of ProcessPrng extern
This removes a bit of duplication and is consistent with how `api-ms-win-core-synch-l1-2-0` externs are imported.

A partial stabilization that only affects:
- AllocType<T>::new_uninit
- AllocType<T>::assume_init
- AllocType<[T]>::new_uninit_slice
- AllocType<[T]>::assume_init
where "AllocType" is Box, Rc, or Arc

exit: explain our expectations for the exit handlers registered in a Rust program
This documents the position of ``@Amanieu`` and others in https://github.com/rust-lang/rust/issues/126600: a library with an atexit handler that destroys state that other threads could still be working on is buggy. We do not consider it acceptable for a library to say "you must call the following cleanup function before exiting from `main` or calling `exit`". I don't know if this is established ``@rust-lang/libs-api`` consensus so I presume this will have to go through FCP.
Given that Rust supports concurrency, I don't think there is any way to write a sound Rust wrapper around a library that has such a required cleanup function: even if we made `exit` unsafe, and the Rust wrapper used the scope-with-callback approach to ensure it can run cleanup code before returning from the wrapper (like `thread::scope`), one could still call this wrapper in a second thread and then return from `main` while the wrapper runs. Making this sound would require `std` to provide a way to "block" returning from `main`, so that while the wrapper runs returning from `main` waits until the wrapper is done... that just doesn't seem feasible.
The `exit` docs do not seem like the best place to document this, but I also couldn't think of a better one.

pal/hermit: correctly round up microseconds in `Thread::sleep`

library: Move unstable API of new_uninit to new features
- `new_zeroed` variants move to `new_zeroed_alloc`
- the `write` fn moves to `box_uninit_write`
The remainder will be stabilized in upcoming patches, as it was decided to only stabilize `uninit*` and `assume_init`.
