The following methods are made unstable const under the const_socketaddr feature (#82485):

// std::net

impl SocketAddr {
    pub const fn ip(&self) -> IpAddr;
    pub const fn port(&self) -> u16;
    pub const fn is_ipv4(&self) -> bool;
    pub const fn is_ipv6(&self) -> bool;
}

impl SocketAddrV4 {
    pub const fn ip(&self) -> IpAddr;
    pub const fn port(&self) -> u16;
}

impl SocketAddrV6 {
    pub const fn ip(&self) -> IpAddr;
    pub const fn port(&self) -> u16;
    pub const fn flowinfo(&self) -> u32;
    pub const fn scope_id(&self) -> u32;
}

Note: SocketAddrV4::ip and SocketAddrV6::ip use pointer casting and depend on the unstable feature const_raw_ptr_deref

Team member @joshtriplett has proposed to merge this. The next step is review by the rest of the tagged team members:

No concerns currently listed.

Once a majority of reviewers approve (and at most 2 approvals are outstanding), this will enter its final comment period. If you spot a major issue that hasn't been raised at any point in this process, please speak up!

See this document for info about what commands tagged team members can give me.

This PR makes the methods unstably const, but since there is already an FCP shall I just make them stable const? This PR also doesnt include SocketAddr::new yet.

@CDirkx @joshtriplett Hmmm, yeah I don't think we usually do an FCP for small unstable API additions.

I think we do generally want APIs to bake on unstable for a bit before stabilizing them though. Maybe we should just cancel this FCP and merge the PR for now?

Constify methods of `std::net::SocketAddr`, `SocketAddrV4` and `SocketAddrV6`

The following methods are made unstable const under the `const_socketaddr` feature (rust-lang#82485):

```rust
// std::net

impl SocketAddr {
    pub const fn ip(&self) -> IpAddr;
    pub const fn port(&self) -> u16;
    pub const fn is_ipv4(&self) -> bool;
    pub const fn is_ipv6(&self) -> bool;
}

impl SocketAddrV4 {
    pub const fn ip(&self) -> IpAddr;
    pub const fn port(&self) -> u16;
}

impl SocketAddrV6 {
    pub const fn ip(&self) -> IpAddr;
    pub const fn port(&self) -> u16;
    pub const fn flowinfo(&self) -> u32;
    pub const fn scope_id(&self) -> u32;
}
```

Note: `SocketAddrV4::ip` and `SocketAddrV6::ip` use pointer casting and depend on the unstable feature `const_raw_ptr_deref`
