Refactor `Face` to support [[NDNLPv2]] link service and permanent faces. High-level design: <https://gist.github.com/yoursunny/22a7d53711b4e9bc198a> This issue includes: * Design initialization logic for every `Socket` type, including `UnixSocket UdpSocket TcpSocket EthernetSocket WebSocketSocket`. * Implement `LinkService` a `NullLinkService` that merely passes through packets between network layer and `Socket` base classes. link layer. * Implement a non-inheritable `Face` class that connects a `LinkService` and `Socket`. * Implement a `NullLinkService` that merely passes through packets between network layer and link layer. * In all `Factory` and `Channel` subclasses, replace the initialization of `UnixStreamFace UdpFace TcpFace EthernetFace WebSocketFace` to the initialization of a `Face` with `NullLinkService` and the corresponding `Socket`. This is an initial step toward a Face that supports [[NDNLPv2]] and full-featured permanent face.
