hg: allow hg.parseurl(url, None)

In many places hg.parseurl is called with a url and "opts.get('rev')",
suggesting the second, optional argument can be None. Because opts['rev']
usually defaults to [] this never happens in practice.

However, extensions don't necessarily behave the same, but do copy this
pattern.

Also, include wider hg.parseurl tests, beyond a demonstration of the problem.
