As shown in the PL011 device, the orphan rules required a manual implementation of ClassInitImpl for anything not in the qemu_api crate; this gets in the way of moving system emulation-specific code (including DeviceClass, which as a blanket ClassInitImpl<DeviceClass> implementation) into its own crate. Make ClassInitImpl optional, at the cost of having to specify the CLASS_INIT member by hand in every implementation of ObjectImpl. The next commits will get rid of it, replacing all the "impl<T> ClassInitImpl<Class> for T" blocks with a generic class_init<T> method on Class. Right now the definition is always the same, but do not provide a default as that will not be true once ClassInitImpl goes away.

QEMU bindings and API wrappers
This library exports helper Rust types, Rust macros and C FFI bindings for internal QEMU APIs.
The C bindings can be generated with bindgen, using this build target:
$ make bindings.inc.rs
Generate Rust documentation
Common Cargo tasks can be performed from the QEMU build directory
$ make clippy
$ make rustfmt
$ make rustdoc
