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.
