Having `Cargo.toml` at the top-level of the repository implies that one
can run `cargo build` directly, but this doesn't produce anything useful
on its own.

Additionally, when including the git source as a submodule of a Rust
project, it prevents the git source from being included at all in the
crate package because cargo skips directories that contain a Cargo.toml,
assuming that everything in the directory is relevant to the crate.

Move all Rust-specific files into a dedicated `rust/` subdirectory.

This still leaves the source tree in somewhat inconsistent state.

I do not offhand know if ci/run-rust-checks.sh needs updating or the
moving of files needs tweaking to avoid the breakage, though.
