    libide/sourceview: start removing more legacy cruft
    
    A lot of this gets simplified with GtkSourceView 5.x and we wont be
    maintaining all of it in Builder anymore. Any sort of movements that
    need abstraction belong in GtkSourceView directly (or have already been
    ported there in the form of Vim motions/text-objects).
