docs: Respond to HTTP requests.  The following responders are mostly just wrappers around sg._XXX() functions. But it adds the element of 'knowing' that the `req` came from an unfriendly client.  This module will 'scrub' responses such that unfriendly clients do not get leaked information, and logs when it sees an unfriendly client. This is just a last-line safety measure.  The caller is expected to actually do something about unfriendly clients. Then, they let us know that they have successfully taken care of the request by calling assumedUnfriendly().
