rust: add definitions for vmstate
Add a new qemu_api module, `vmstate`. Declare a bunch of Rust
macros declared that are equivalent in spirit to the C macros in
include/migration/vmstate.h.
For example the Rust of equivalent of the C macro:
VMSTATE_UINT32(field_name, struct_name)
is:
vmstate_uint32!(field_name, StructName)
This breathtaking development will allow us to reach feature parity between
the Rust and C pl011 implementations.
