* The TestNet protocol starts with a terminal resize escape sequence, so
the server discards all input until it sees the sequence, and it delays
starting the agent. Eventually, the goal is to implement an SSH server,
and the SSH message that creates a PTY also provides the terminal size.
- Add a very incomplete "telnet" server. It doesn't recognize any telnet
commands, so it's "telnet" only in the sense that I can connect to the
server and type commands. The commands are fed to a Win32 Console, but
I don't get to see the output over the network.
- Move AgentClient to the Shared directory and move QtEvent-specific code
out of it.
- Move the startShell routine into the AgentClient so I can share it
between the different console-consuming prototypes.
