2018-02-21	Update the .gitmodules to refer to project-level tor-rust-dependencies	Nick Mathewson
	Closes most of #25323.
2017-05-19	Allow Rust build using locally supplied crates or crates.io	Sebastian Hahn
	This adds a couple of configure commands to control whether we're requiring all dependencies to be available locally (default) or not (--enable-cargo-online-mode). When building from a tarball, we require the RUST_DEPENDENCIES variable to point to the local repository of crates. This also adds src/ext/rust as a git submodule that contains such a local repository for easy setup.
