std: Rename io to old_io
In preparation for the I/O rejuvination of the standard library, this commit
renames the current `io` module to `old_io` in order to make room for the new
I/O modules. It is expected that the I/O RFCs will land incrementally over time
instead of all at once, and this provides a fresh clean path for new modules to
enter into as well as guaranteeing that all old infrastructure will remain in
place for some time.

As each `old_io` module is replaced it will be deprecated in-place for new
structures in `std::{io, fs, net}` (as appropriate).

This commit does *not* leave a reexport of `old_io as io` as the deprecation
lint does not currently warn on this form of use. This is quite a large breaking
change for all imports in existing code, but all functionality is retained
precisely as-is and path statements simply need to be renamed from `io` to
`old_io`.

-//! TCP network connections
-//!
-//! This module contains the ability to open a TCP stream to a socket address,
-//! as well as creating a socket server to accept incoming connections. The
-//! destination and binding addresses can either be an IPv4 or IPv6 address.
-//!
-//! A TCP connection implements the `Reader` and `Writer` traits, while the TCP
-//! listener (socket server) implements the `Listener` and `Acceptor` traits.
