When pass a varray to vmstate_struct, the `type` parameter should be the type of the element in the varray, for example: vmstate_struct!(HPETState, timers, [0 .. num_timers], VMSTATE_HPET_TIMER, BqlRefCell<HPETTimer>).with_version_id(0) But this breaks current type check, because it checks the type of `field`, which is an array type (for the above example, type of timers is [BqlRefCell<HPETTimer>; 32], not BqlRefCell<HPETTimer>). But the current assert_field_type() can no longer be extended to include new arguments, so a variant of it (a second macro containing the `num = $num:ident` parameter) had to be added to handle array cases. In this new macro, it not only checks the type of element, but also checks whether the `num` (number of elements in varray) is out of range.

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
