Allows using
externin paths to unambiguously refer to items in extern crates -extern::my_crate::foo.This feature is superseded by absolute paths
::my_crate::fooon 2018 edition, and has little value on 2015 edition whereextern crateitems are supposed to be used instead.As a result, the feature is supposed to be removed once 2018 edition ships.
