rust: Use a maintained crate for SHA-1 hashing https://crates.io/crates/rust-crypto hasn?t been updated in 5 years. This doesn?t neccesarily mean there?s anything wrong with it, but if something comes up it?s preferable to rely on libraries that have active maintainers. Use https://crates.io/crates/sha-1 from https://github.com/RustCrypto instead Differential Revision: https://phab.mercurial-scm.org/D10835
