Add doc for impl From for Addr
As part of issue #51430 (cc @skade).
The impl is very simple, let me know if we need to go into any details.
Additionally, I added `#[inline]` for the conversion method, let me know if it is un-necessary or might break something.
Rollup of bare_trait_objects PRs
All deny attributes were moved into bootstrap so they can be disabled with a line of config.
Warnings for external tools are allowed and it's up to the tool's maintainer to keep it warnings free.

These are unstable, and were deprecated by #47510, since Rust 1.25. The
internal `sys` implementations are still kept to support the call in the
common `resolve_socket_addr`.
Clarify network byte order conversions for integer / IP address conversions.
Opened primarily to address https://github.com/rust-lang/rust/issues/48819.
Also added a few other conversion docs/examples.
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.

There are some tests that need to be disabled on CloudABI specifically,
due to the fact that the shims cannot be built in combination with
unix::ext or windows::ext. Also improve the scoping of some imports to
suppress compiler warnings.
