rHG86b22a4cfab1: wireprotov2: client support for advertising redirect targets
Summary

With the server now able to emit a redirect target descriptor, we can
start to teach the client to recognize it.

This commit implements support for filtering the advertised
redirect targets against supported features and for advertising
compatible redirect targets as part of command requests. It also
adds the minimal boilerplate required to fail when a content
redirect is seen.

The server doesn't yet do anything with the advertised redirect
targets. And the client can't yet follow redirects if it did. But
at least we're putting bytes on the wire.
