Some lookalike sites are configured to redirect to their canonical counterparts.
The most common example is an IDN redirecting to the ASCII domain (e.g.
elespañol[.]com to elespanol[.]com). Currently, such redirects are blocked with
an interstitial, even though the navigation is harmless.

This CL treats a subset of such redirects as safe and allows them to go proceed
without an interstitial. In order to be deemed safe, the initial URL must
redirect to the same eTLD+1 of the URL it's visually similar to. It should also
redirect to the root of the domain without any path components. This should
cut down the number of extraneous interstitials we currently show for defensive
registrations.
