+Subject: [PATCH] gvariant: Zero-initialise various GVariantSerialised objects
+
+The following few commits will add a couple of new fields to
+`GVariantSerialised`, and they should be zero-filled by default.
+
+Try and pre-empt that a bit by zero-filling `GVariantSerialised` by
+default in a few places.
