    GVariant: clear memory before releasing it
    
    Bug #640807 makes a reasonable case for why it's better to have your
    program crash outright in the case of memory errors.  With this
    modification, GVariant is far more likely to do that in the case that a
    GVariant pointer is used shortly after being freed.
