[tor-commits] [tor/master] Allow Rust build using locally supplied crates or crates.io
commit 70c067102b7d2576fa456d2872bb41abf559dff6
Author: Sebastian Hahn <sebastian@xxxxxxxxxxxxxx>

Allow Rust build using locally supplied crates or crates.io
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.
