    sourceview: add IdeSourceView::focus-location gsignal
    
    This signal is emitted when the sourceview has determined that it needs
    to jump to a new source location. This could happen after resolving
    a type that we'd like to jump to, or a multitude of things we haven't
    thought about yet.
    
    This is also subject to change, but makes forward progress.
