Newer versions of Android forbid the creation of hardlinks as well as
Unix domain sockets in the /data filesystem via SELinux rules, which
causes several tests depending on this behavior to fail. So let's
skip these tests on Android with an #[ignore] directive.

Replace most uses of `pointer::offset` with `add` and `sub`
As PR title says, it replaces `pointer::offset` in compiler and standard library with `pointer::add` and `pointer::sub`. This generally makes code cleaner, easier to grasp and removes (or, well, hides) integer casts.
This is generally trivially correct, `.offset(-constant)` is just `.sub(constant)`, `.offset(usized as isize)` is just `.add(usized)`, etc. However in some cases we need to be careful with signs of things.

This updates the standard library's documentation to use the new syntax. The
documentation is worthwhile to update as it should be more idiomatic
(particularly for features like this, which are nice for users to get acquainted
with). The general codebase is likely more hassle than benefit to update: it'll
hurt git blame, and generally updates can be done by folks updating the code if
(and when) that makes things more readable with the new format.
A few places in the compiler and library code are updated (mostly just due to
already having been done when this commit was first authored).

The creation of libc::sockaddr_un is a safe operation, no need for it to
be unsafe.
This also uses the more performant copy_nonoverlapping instead of an
iterator.

Implement most of RFC 2930, providing the ReadBuf abstraction
This replaces the `Initializer` abstraction for permitting reading into uninitialized buffers, closing #42788.
This leaves several APIs described in the RFC out of scope for the initial implementation:
* read_buf_vectored
* `ReadBufs`
Closes #42788, by removing the relevant APIs.

Add #[must_use] to remaining std functions (O-Z)
I've run out of compelling reasons to group functions together across crates so I'm just going to go module-by-module. This is half of the remaining items from the `std` crate, from O-Z.
`panicking::take_hook` has a side effect: it unregisters the current panic hook, returning it. I almost ignored it, but the documentation example shows `let _ = panic::take_hook();`, so following suit I went ahead and added a `#[must_use]`.
```rust
std::panicking fn take_hook() -> Box<dyn Fn(&PanicInfo<'_>) + 'static + Sync + Send>;
```
I added these functions that clippy did not flag:
```rust
std::path::Path fn starts_with<P: AsRef<Path>>(&self, base: P) -> bool;
std::path::Path fn ends_with<P: AsRef<Path>>(&self, child: P) -> bool;
std::path::Path fn with_file_name<S: AsRef<OsStr>>(&self, file_name: S) -> PathBuf;
std::path::Path fn with_extension<S: AsRef<OsStr>>(&self, extension: S) -> PathBuf;
```

Add abstract namespace support for Unix domain sockets
Hello! The other day I wanted to mess around with UDS in Rust and found that abstract namespaces ([unix(7)](https://man7.org/linux/man-pages/man7/unix.7.html)) on Linux still needed development. I took the approach of adding `_addr` specific public functions to reduce conflicts.
Feature name: `unix_socket_abstract`
Tracking issue: #85410
Further context: #42048
## Non-platform specific additions
`UnixListener::bind_addr(&SocketAddr) -> Result<UnixListener>`
`UnixStream::connect_addr(&SocketAddr) -> Result<()>`
`UnixDatagram::bind_addr(&SocketAddr) -> Result<UnixDatagram>`
`UnixDatagram::connect_addr(&SocketAddr) -> Result<()>`
`UnixDatagram::send_to_addr(&self, &[u8], &SocketAddr) -> Result<usize>`
## Platform-specific (Linux) additions
`SocketAddr::from_abstract_namespace(&[u8]) -> SocketAddr`
`SockerAddr::as_abstract_namespace() -> Option<&[u8]>`
## Example
```rust
#![feature(unix_socket_abstract)]
use std::os::unix::net::{UnixListener, SocketAddr};
fn main() -> std::io::Result<()> {
let addr = SocketAddr::from_abstract_namespace(b"namespace")?; // Linux only
let listener = match UnixListener::bind_addr(&addr) {
Ok(sock) => sock,
Err(err) => {
println!("Couldn't bind: {:?}", err);
return Err(err);
}
};
Ok(())
}
```
## Further Details
The main inspiration for the implementation came from the [nix-rust](https://github.com/nix-rust/nix/blob/master/src/sys/socket/addr.rs#L558) crate but there are also other [historical](https://github.com/rust-lang/rust/commit/c4db0685b181f12c4285dac3d932f1859bba74f5) [attempts](https://github.com/tormol/uds/blob/master/src/addr.rs#L324) with similar approaches.
A comment I did have was with this change, we now allow a `SocketAddr` to be constructed explicitly rather than just used almost as a handle for the return of `peer_addr` and `local_addr`. We could consider adding other explicit constructors (e.g. `SocketAddr::from_pathname`, `SockerAddr::from_unnamed`).
Cheers!
