commit 497e40ad03c27837978551ba15491c3fb2a0bf53
Author: Noel Grandin <noel.grandin at collabora.co.uk>
Date:   Thu Jun 29 08:15:20 2017 +0200

    improve refcounting loplugin
    
    to find ref-counted classes being managed via other smart pointer
    classes.
    Hopefully prevent needing fixes like
    642ae256ea5b8083ba0b3c097ca8ea52304b9cdb
    "ChangedUIEventListener is refcounted, mustn't be helt by unique_ptr"
