  Implement the server side of the rpkk-router protocol.  Other than
  one PF_UNIX socket inode, this doesn't write anything to disk, so it
  can be run with minimal privileges.  Most of the work has already
  been done by the database generator, so all this server has to do is
  pass the results along to a client.
