Use Arc::clone and Rc::clone in documentation
This PR replaces uses of `x.clone()` by `Rc::clone(&x)` (or `Arc::clone(&x)`) to better match the documentation for those types.

Unfortunately this is not quite ready to go because the newly-working links trigger a bunch of linkcheck failures. The failures are tough to fix because the links are resolved relative to the implementor, which could be anywhere in the module hierarchy.
(In the current docs, these links end up rendering as uninterpreted markdown syntax, so I don't think these failures are any worse than the status quo. It might be acceptable to just add them to the linkchecker whitelist.)
Ideally this could be fixed with intra-doc links ~~but it isn't working for me: I am currently investigating if it's possible to solve it this way.~~ Opened #73829.
EDIT: This is now ready!
Convert many files to intra-doc links

I recommend reviewing one commit at a time, but the diff is small enough you can do it all at once if you like :)
Applied `#![deny(unsafe_op_in_unsafe_fn)]` in library/std/src/wasi
partial fix for #73904
There are still more that was not applied in [mod.rs]( 38fab2ea92/library/std/src/sys/wasi/mod.rs) and that is due to its using files from `../unsupported`
like:
```
#[path = "../unsupported/cmath.rs"]
pub mod cmath;
```
Make all methods of `std::net::Ipv4Addr` const
Make the following methods of `std::net::Ipv4Addr` unstable const under the `const_ipv4` feature:
- `octets`
- `is_loopback`
- `is_private`
- `is_link_local`
- `is_global` (unstable)
- `is_shared` (unstable)
- `is_ietf_protocol_assignment` (unstable)
- `is_benchmarking` (unstable)
- `is_reserved` (unstable)
- `is_multicast`
- `is_broadcast`
- `is_documentation`
- `to_ipv6_compatible`
- `to_ipv6_mapped`
This would make all methods of `Ipv6Addr` const.
Of these methods, `is_global`, `is_broadcast`, `to_ipv6_compatible`, and `to_ipv6_mapped` require a change in implementation.
Part of #76205
Add a note for Ipv4Addr::to_ipv6_compatible
Previous discussion: #75019
> I think adding a comment saying "This isn't typically the method you want; these addresses don't typically function on modern systems. Use `to_ipv6_mapped` instead." would be a good first step, whether this method gets marked as deprecated or not.

- Use intra-doc links for `std::io` in `std::fs`
- Use intra-doc links for File::read in unix/ext/fs.rs
- Remove explicit intra-doc links for `true` in `net/addr.rs`
- Use intra-doc links in alloc/src/sync.rs
- Use intra-doc links in src/ascii.rs
- Switch to intra-doc links in alloc/rc.rs
- Use intra-doc links in core/pin.rs
- Use intra-doc links in std/prelude
- Use shorter links in `std/fs.rs`
`io` is already in scope.
Make all methods of `std::net::Ipv6Addr` const
Make the following methods of `std::net::Ipv6Addr` unstable const under the `const_ipv6` feature:
- `segments`
- `is_unspecified`
- `is_loopback`
- `is_global` (unstable)
- `is_unique_local`
- `is_unicast_link_local_strict`
- `is_documentation`
- `multicast_scope`
- `is_multicast`
- `to_ipv4_mapped`
- `to_ipv4`
This would make all methods of `Ipv6Addr` const.
Changed the implementation of `is_unspecified` and `is_loopback` to use a `match` instead of `==`, all other methods did not require a change.
All these methods are dependent on `segments`, the current implementation of which requires unstable `const_fn_transmute` ([PR#75085](https://github.com/rust-lang/rust/pull/75085)).

This reverts commit 7e2548fe69.
Now I know why it was redefined: it seems like it's potentially because
of the orphan rule. Here are the error messages:
error[E0119]: conflicting implementations of trait `std::fmt::Debug` for type `!`:
--> src/primitive_docs.rs:236:1
|
6 | impl Debug for ! {
| ^^^^^^^^^^^^^^^^

= note: conflicting implementation in crate `core`:
- impl std::fmt::Debug for !;
error[E0117]: only traits defined in the current crate can be implemented for arbitrary types

Constify the following methods of `std::net::Ipv4Addr`:
- `octets`
- `is_loopback`
- `is_private`
- `is_link_local`
- `is_shared`
- `is_ietf_protocol_assignment`
- `is_benchmarking`
- `is_multicast`
- `is_documentation`
Also insta-stabilizes these methods as const.
Possible because of the stabilization of const integer arithmetic and control flow.
