    libide/terminal: add ide_terminal_page_new_completed()
    
    This is a convenience function to setup a new terminal page that is
    intended for display purposes only such as the contents of a previously
    run terminal (ie: previous application session).
    
    We want to keep the state around to be reused, but otherwise interacting
    with the terminal is not supported.
