Crate idna_adapter

This crate abstracts over a Unicode back end for the idna crate.

To work around the lack of global-features in Cargo, this crate allows the top level Cargo.lock to choose an alternative Unicode back end for the idna crate by pinning a version of this crate.

See the README of the latest version for more details.
