Splitting otexstream into otexrowstream and otexstream.
otexstream used to count lines to build a TexRow, and some other things. The new class otexrowstream has the line counting feature of the previous otexstream without other stuff. otexstream is now a subclass of otexrowstream that has the same features as before. This is preliminary work for extending the cursor<->row tracking to math.
