* Some users might think they could run winpty-agent.exe.
* Right now, when I run winpty-agent.exe from a cmd.exe command prompt

- Update the Agent to use separate control and data pipes and to receive
arbitrary-sized packets. Handle child process creation in the agent.

- Don't close the desktop and window station until after connecting
to the agent's pipes.
- Change the format of the pconsole_start_process env parameter from an
array of wide-character-string pointers to a single contiguous block of
memory, like that accepted by CreateProcess.
