Subject: Properly re-implement userinfo parsing (rfc2396)
* src/url.c (url_skip_credentials): Properly re-implement userinfo parsing (rfc2396)
The reason why the implementation is based on RFC 2396, an outdated standard,
is that the whole file is based on that RFC, and mixing standard here might be
dangerous.
