Pseudo terminal or named pipe

[LucaCiucci]

We should introduce, fome mechanism to receive the gnulot output. For example:

• On whindows, a Named Pipe or a pseudo terminal PTY, PTY creation
• On Linux some sort of pipe duplication, fork, or PTY, also see gpReadMouseTest.c example
• No read when not available on the current system or streambuf, also MultiStream class should use the operator >> with only one of the streambufs and a function to get the output of >> for every streambuf that allows reading
