Feature #3166
Updated by Junxiao Shi about 9 years ago
Implement `TcpTransport` for use with LinkService. The `TcpTransport` is a subclass of [`Transport`](https://gist.github.com/yoursunny/22a7d53711b4e9bc198a) that communicates with either a local application or a remote forwarder via TCP socket forwarder. * `TcpTransport` is local if RemoteUri contains a loopback address; otherwise it's non-local. * `TcpTransport` can be on-demand, persistent, or permanent. However, in this issue only on-demand and persistent are supported. After implementing `TcpTransport`: * change `TcpChannel` to initialize an `LpFace(SimpleLinkService+TcpTransport)` in place of `TcpFace` * delete old `TcpFace` and `TcpLocalFace`
