subrepos: use url.url when normalizing repo paths This works around an issue in older versions of Python that would strip double slashes from SSH URLs when using urlunparse() on a parsed URL.

url: provide url object This adds a url object that re-implements urlsplit() and unsplit(). The implementation splits out usernames, passwords, and ports. The implementation is based on the behavior specified by RFC 2396[1]. However, it is much more forgiving than the RFC's specification; it places no specific restrictions on what characters are allowed in each segment of the URL other than what is necessary to split the URL into its constituent parts.
