LibVT+Everywhere: Introduce 'automarks' and 'clear previous command'
Automarks are similar to bookmarks placed by the terminal, allowing the user to selectively remove a single command and its output from the terminal scrollback. This commit implements a single way to add marks: automatically placing them when the shell becomes interactive. To make sure the shell behaves correctly after its expected prompt position changes, the terminal layer forces a resize event to be passed to the shell on such (possibly) partial clears; this also has the nice side effect of fixing the disappearing prompt on the preexisting "clear including history" action: Fixes #4192.
