terminal: add term_linefeed() and term_reverse_index()

Browse source 
linefeed moves cursor down one row (columns stays the same), or, if
the cursor is at the last row, scrolls up one row.

reverse_index does the opposite; it moves the cursor *up* one row, or,
if the cursor is at the top row, scrolls *down* one row.
