rfc1413.c fixes:

1) we were retrieving our local port before APR filled it in; wait a
   little longer :)
   (maybe APR needs to be a little smarter about when/if to call
   getsockname()?  it could call it when the info is first needed and
   not do it at all if never needed)
2) when the server dropped the connection before sending a properly-
   delimited response, we entered a hard loop; we weren't reacting to
   EOF/FIN properly
