debug: add a 'debugdownload' command This command resolve and fetch and URL through the Mercurial logic. Mercurial logic add various headers (including authentication) while resolving an URL so the commands helps with building the same request Mercurial would be doing. A new test file is created because we'll add more logic regarding Mercurial download logic and it will grow to a reasonable size.
