This series integrates some of the observations from the MSRV patches at https://lore.kernel.org/qemu-devel/20241015131735.518771-1-pbonz...@redhat.com/.
The main changes here are two: first, build an integration test that actually tries to create a QOM object that is defined by Rust code; second, make the properties array immutable so that declare_properties! is enforced to use only const-friendly constructs. These are patches 6-11; the others consist of small cleanups. Hidden in here is actually a C patch (#10) which makes the bindgen-generated prototypes use "*const" instead of "*mut". Tested with Rust nightly and (together with more patches from the RFC), with Rust 1.63.0. Unlike the MSRV patches, this should be ready for inclusion; the changes should be mostly uncontroversial.
