Paolo Bonzini c596199f63 rust: cell: add BQL-enforcing RefCell variant 
Similar to the existing BqlCell, introduce a custom interior mutability
primitive that resembles RefCell but accounts for QEMU's threading model.
Borrowing the RefCell requires proving that the BQL is held, and
attempting to access without the BQL is a runtime panic.

Almost all of the code was taken from Rust's standard library, while
removing unstable features and probably-unnecessary functionality that
amounts to 60% of the original code.  A lot of what's left is documentation,
as well as unit tests in the form of doctests.  These are not yet integrated
in "make check" but can be run with "cargo test --doc".

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
