Parse the repository URL's netloc, and return the new netloc to use
along with auth information.
Args:
netloc: the original repository URL netloc.

This is mainly for the Subversion class to override, so that auth
information can be provided via the --username and --password options
instead of through the URL. For other subclasses like Git without
such an option, auth information must stay in the URL.
Returns: (netloc, (username, password)).
