    Terminal scrollback with ring buffer

    This patch adds a ring buffer for scrollback to the terminal.  The
    advantage of using a ring buffer is that the common case, scrolling with
    no static screen content, can be achieved very efficiently by
    incrementing and decrementing the starting line (modulo buffer size).

    The scrollback buffer is limited to HISTSIZE lines in order to bound
    memory usage. As the lines are allocated on demand, it is possible to
    implement unlimited scrollback with few changes.  If the terminal is
    reset, the scroll back buffer is reset, too.
