GUACAMOLE-148: Fix handling of terminal scroll.
Terminal emulators maintain the scrolling region and the bounds of the
terminal separately. Console codes which allow the scrolling region to be
redefined facilitate utilities like top, tmux, or screen which must maintain
control of what scrolls and what doesn't.
Guacamole handles scrolling improperly, automatically scrolling whenever
the cursor exceeds the bounds of the scroll region. This is only correct
behavior when the cursor is within the scrolling region. The terminal should
not be scrolled *at all* when the cursor is outside the scrolling region. If
outside the scrolling region, the cursor should simply be kept within terminal
bounds.
