This patch a adds new terminal type, TtyTerm, to TerminalDxe. This terminal type provides a place to add support for various *nix terminals that don't behave like standard VT terminals. The goal is to 'just work' with as many terminals as possible, rather than properly emulating any one specific terminal.
