    glib-genmarshal: Fix ref-sinking of GVariants in valist marshallers
    
    The old (Perl) implementation of glib-genmarshal used
    g_variant_ref_sink() to correctly handle floating inputs; the Python
    version should do the same.
    
    Backported version of !904 does not include the unit test. The version
    of this on `master` includes a unit test.

    Fixes: #1793
