- Wrote a LOOKUP-HOST front-end that uses DNS-QUERY.
  Passes the LOOKUP-HOST.* tests.
- Old code still there.  Delete later, perhaps.

- Echo client works.
- WITH-DEFERRED-RESULT turns its body into a synchronous
  call when there isn't an event-base to work with.
- Fixed other silly bugs.

Lots of details missing, but the server works. Yay!

- export stuff from the io.event package.
- lots of ad-hoc changes to get echo server working.
