4e2797dd76 Implement Neg for signed non-zero integers.
Negating a non-zero integer currently requires unpacking to a
primitive and re-wrapping. Since negation of non-zero signed
integers always produces a non-zero result, it is safe to
implement `Neg` for `NonZeroI{N}`.

The new `impl` is marked as stable because trait implementations
for two stable types can't be marked unstable.

Support AIX-style archive type

Reading facility of AIX big archive has been supported by `object` since 0.30.0.

Writing facility of AIX big archive has already been supported by `ar_archive_writer`, but we need to bump the version to support the new archive type enum.

Use `Display` in top-level example for `PanicInfo`

Addresses https://github.com/rust-lang/rust/issues/110098.

This confused me as well, when I was writing a `no_std` panic handler for the first time, so here's a better top-level example.

`Display` is stable, prints the `.message()` if available, and falls back to `.payload().downcast_ref<&str>()` if the message is not available. So this example should provide strictly more information and also work for formatted panics.

The old example still exists on the `payload` method.

Rollup merge of - schneems:schneems/add-docs-to-command-env-methods, r=Amanieu
Add Command environment variable inheritance docs

The interaction between the environment variable methods can be confusing. Specifically `env_clear` and `remove_env` have a side effects not mentioned: they disable inheriting environment variables from the parent process. I wanted to fully document this behavior as well as explain relevant edge cases in each of the `Command` env methods.

This is further confused by the return of `get_envs` which will return key/None if `remove_env` has been used, but an empty iterator if `env_clear` has been called. Or a non-empty iterator if `env_clear` was called and later explicit mappings are added. Currently there is no way (that I'm able to find) of observing whether or not the internal `env_clear=true` been toggled on the `Command` struct via its public API.

Ultimately environment variable mappings can be in one of several states:

- Explicitly set value (via `envs` / `env`) will take precedence over parent mapping
- Not explicitly set, will inherit mapping from parent
- Explicitly removed via `remove_env`, this single mapping will not inherit from parent
- Implicitly removed via `env_clear`, no mappings will inherit from parent

I tried to represent this in the relevant sections of the docs.

This is my second-ever doc PR (whoop!). I'm happy to take specific or general doc feedback. Also happy to explain the logic behind any changes or additions I made.

Cover edge cases for {f32, f64}.hypot() docs

Fixes 

The Euclidean distance is a more general way to express what these functions do, and covers the edge cases of zero and negative inputs.

Does not cover the case of non-normal input values (as the [POSIX docs](https://pubs.opengroup.org/onlinepubs/9699919799.2008edition/) do), but the docs for the rest of the functions in these modules do not address this, I assumed it was not desired.

Rollup merge of - seanlinsley:patch-1, r=ChrisDenton
Clarify that RUST_MIN_STACK may be internally cached

For larger applications it's important that users set `RUST_MIN_STACK` at the start of their program because [`min_stack`](7d3e03666a/library/std/src/sys_common/thread.rs) caches the value. Not doing so can lead to their `env::set_var` call surprisingly not having any effect.

In my own testing `RUST_MIN_STACK` had no effect until I moved it to the top of `main()`. Hopefully this clarification in the docs will help others going forward.

linkat() not available in the system headers of Solaris 10

I've installed rustup on x86_64-unknown-linux-gnu and would like to use the target sparcv9-sun-solaris. For this, I have built a gcc from the source code for cross-compiling to sparcv9-sun-solaris2.10 with system headers of Solaris 10.

With the following hello word example:
main.rs:
```rust
fn main() {
    println!("Hello, world!");
}
```
I had a compilation error:
