    SourceView: Improve get_source_buffer() and remove deprecated methods.
    
    * gtksourceview/src/sourceview.[hg|ccg]: get_source_buffer():
    Just use RefPtr::cast_dynamic<> here, which is all these methods
    really do. This avoids us having ot worry about reference-counting.
    Also remove the deprecated methods.
