Subject: [PATCH] gvariant-core: Consolidate construction of
`GVariantSerialised`
So I only need to change it in one place.
This introduces no functional changes.
Helps: #2121
CVE: CVE-2023-32665
Upstream-Status: Backport from [https://gitlab.gnome.org/GNOME/glib/-/commit/1deacdd4e8e35a5cf1417918ca4f6b0afa6409b1]
