This patch adds another type to get_remote_name -- REMOTE_NOLOOKUP.
This skips the lookup and returns the name/ip that is known already.
This is then used in update_child_status so that no DNS lookups are
forced for the status page.

On its own, this patch really doesn't do anything :) So why am I
submitting it?  It allows the creative hacker to set up their server
to do reverse dns on some hits but not others.

I imagine something like this would do the trick in 1.2:

    HostnameLookups On
    <Files \.(gif|jpeg)$>
    HostnameLookups Off
    </Files>
