std: Add a net module for TCP/UDP
This commit is an implementation of [RFC 807][rfc] which adds a `std::net` module for basic neworking based on top of `std::io`. This module serves as a replacement for the `std::old_io::net` module and networking primitives in `old_io`. [rfc]: fillmein The major focus of this redesign is to cut back on the level of abstraction to the point that each of the networking types is just a bare socket. To this end functionality such as timeouts and cloning has been removed (although cloning can be done through `duplicate`, it may just yield an error). With this `net` module comes a new implementation of `SocketAddr` and `IpAddr`. This work is entirely based on #20785 and the only changes were to alter the in-memory representation to match the `libc`-expected variants and to move from public fields to accessors.

/// name.
|

/// address. It is needed because sometimes one type is more appropriate than
|

/// the other: for simple uses a string like `"localhost:12345"` is much nicer
|

/// than manual construction of the corresponding `SocketAddr`, but sometimes

/// some other type (e.g. a string) just for it to be converted back to
