Paolo Bonzini ab870fa106 rust: add a bit operation module 
The bindgen supports `static inline` function binding since v0.64.0 as
an experimental feature (`--wrap-static-fns`), and stabilizes it after
v0.70.0.

But the oldest version of bindgen supported by QEMU is v0.60.1, so
there's no way to generate the binding for deposit64() which is `static
inline` (in include/qemu/bitops.h).

Instead, implement it by hand in Rust and make it available for all
unsigned types through an IntegerExt trait. Since it only involves bit
operations, the Rust version of the code is almost identical to the
original C version, but it applies to more types than just u64.

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
