Document when types have OS-dependent sizes
As per issue #43601, types that can change size depending on the
target operating system should say so in their documentation.
I used this template when adding doc comments:
```
The size of a(n) <name> struct may vary depending on the target
operating system, and may change between Rust releases.
```
For enums, I used "instance" instead of "struct".
I added documentation to these types:
```
- std::time::Instant (contains sys::time::Instant)
- std::time::SystemTime (contains sys::time::SystemTime)
- std::io::StdinRaw (contains sys::stdio::Stdin)
- std::io::StdoutRaw (contains sys::stdio::Stdout)
- std::io::Stderr (contains sys::stdio::Stderr)
- std::net::addr::SocketAddrV4 (contains sys::net::netc::sockaddr_in)
- std::net::addr::SocketAddrV6 (contains sys::net::netc::sockaddr_in6)
- std::net::addr::SocketAddr (contains std::net::addr::SocketAddrV4 and SocketAddrV6)
- std::net::ip::Ipv4Addr (contains sys::net::netc::in_addr)
- std::net::ip::Ipv6Addr (contains sys::net::netc::in6_addr)
- std::net::ip::IpAddr (contains std::net::ip::Ipv4Addr and Ipv6Addr)
```
I also found that these types varied in size; however, I don't think they need documentation, as it's already fairly obvious that they change based on different OS's:
```
- std::fs::DirBuilder (contains sys::fs::DirBuilder)
- std::fs::FileType (contains sys::fs::FileType)
- std::fs::Permissions (contains sys::fs::FilePermissions)
- std::fs::OpenOptions (contains sys::fs::OpenOptions)
- std::fs::DirEntry (contains sys::fs::DirEntry)
- std::fs::ReadDir (contains sys::fs::ReadDir)
- std::fs::Metadata (contains sys::fs::FileAttr)
- std::fs::File (contains sys::fs::File)
- std::process::Child (contains sys::process::Process)
- std::process::ChildStdin (contains sys::process::AnonPipe)
- std::process::ChildStdout (contains sys::process::AnonPipe)
- std::process::ChildStderr (contains sys::process::AnonPipe)
- std::process::Command (contains sys::process::Command)
- std::process::Stdio (contains sys::process::Stdio)
- std::process::ExitStatus (contains sys::process::ExitStatus)
- std::process::Output (contains std::process::ExitStatus)
- std::sys_common::condvar::Condvar (contains sys::condvar::Condvar)
- std::sys_common::mutex::Mutex (contains sys::mutex::Mutex)
- std::sys_common::net::LookupHost (contains sys::net::netc::addrinfo)
- std::sys_common::net::TcpStream (contains sys::net::Socket)
- std::sys_common::net::TcpListener (contains sys::net::Socket)
- std::sys_common::net::UdpSocket (contains sys::net::Socket)
- std::sys_common::remutex::ReentrantMutex (contains sys::mutex::ReentrantMutex)
- std::sys_common::rwlock::RWLock (contains sys::rwlock::RWLock)
- std::sys_common::thread_local::Key (contains sys::thread_local::Key)
```
Maybe we should just put a comment about the size of structs in the module-level docs for `fs`, `process`, and `sys_common`?
If anyone can think of other types that can change size, comment below. I'm also open to changing the wording.
closes #43601.

Minor message/label formatting consistency fix.
The unimplemented label for `Termination` was missing some backticks for consistency with the message.

Reduce scope of unsafe block in sun_path_offset
I reduced the scope of the unsafe block to the `uninitialized` call which is the only actual unsafe bit.

Fixed clockwise/counter-clockwise in atan2 documentation in f32 and f64 and included that it returns radians

Document format_args! / Arguments<'a> behavior wrt. Display and Debug
This is a follow up PR to #49067 , this documents the behavior of `format_args!` (i.e: `Argument<'a>`) wrt. `Display` and `Debug`.

Stabilize termination_trait, split out termination_trait_test
For #48453.
First time contribution, so I'd really appreciate any feedback on how this PR can be better.
Not sure exactly what kind of documentation update is needed. If there is no PR to update the reference, I can try doing that this week as I have time.

Fix Issue #48345, is_file, is_dir, and is_symlink note mutual exclusion
The methods on the structures `fs::FileType` and `fs::Metadata` of (respectively) `is_file`, `is_dir`, and `is_symlink` had some ambiguity in documentation, where it was not noted whether files will pass those tests exclusively or not. It is now written that the tests are mutually exclusive.
Fixes #48345.

Deprecate the AsciiExt trait in favor of inherent methods
The trait and some of its methods are stable and will remain.
Some of the newer methods are unstable and can be removed later.

Add BufReader::buffer
This subsumes the need for an explicit is_empty function, and provides
access to the buffered data itself which has been requested from time to
time.
We could call this `buf` to match `fill_buf`, but I think I'd prefer `fill_buffer` anyways in hindsight.

The expected behavior is that the environment's PATH should be used
to find the process. posix_spawn() could be used if we iterated
PATH to search for the binary to execute. For now just skip
posix_spawn() if PATH is modified.

Remove or hide deprecated unstable SipHasher{13,24}
Deprecated since Rust 1.13.0.

This stabilizes `main` with non-() return types; see #48453.
