commit c8a5e33fcdde322f486d6c69e7e16fa346793fc9

    Suppress false positives in static analysis
    
    there's more work to do...
    
    The whole nx-X11/extras dir is no longer checked since we only have
    Mesa there and we do not want to check that mess...
    
    All the exceptions in static-analysis-suppressions have been manually
    checked.
