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.

Signed-off-by: Philip Withnall <pwithnall@endlessos.org>

Helps: #2121
