This commit is an implementation of [RFC 1174][rfc] which adds three new traits to the standard library: * `IntoRawFd` - implemented on Unix for all I/O types (files, sockets, etc) * `IntoRawHandle` - implemented on Windows for files, processes, etc * `IntoRawSocket` - implemented on Windows for networking types [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/1174-into-raw-fd-socket-handle-traits.md Closes #27062
