Paolo Bonzini 66bcc554d2 rust: callbacks: allow passing optional callbacks as ()
In some cases, callbacks are optional.  Using "Some(function)" and "None"
does not work well, because when someone writes "None" the compiler does
not know what to use for "F" in "Option<F>".

Therefore, adopt () to mean a "null" callback.  It is possible to enforce
that a callback is valid by adding a "let _: () = F::ASSERT_IS_SOME" before
the invocation of F::call.

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
