Traditional \E[2J sequence erases console display but scroll-back buffer and underlying device (frame) buffer keep data that can be accessed by scrolling console back. This patch introduce new \E[J parameter 3 that allows to scramble scroll-back buffer explicitly. Session locking programs (screen, vlock) can use it to prevent attacker to browse locked console history.
