draft packet tests - using pipe trick turns out not to work, though.

+Queued Packet Tests
+===================
+
+Eventually we'll want tests that install a realm (or several) and
+actually send and receive packets against them, so-called "system
+tests".  In the meantime, a faster and more local test that
+synthesizes packets and feeds them through the queuing mechanism will
+get us some more coverage.

+TODO: cook up test-specific notices, but for now we've got some lying
+around from above...

+
+zcount ends up being -1, because recvfrom gives 'Socket operation on
+non-socket' (ENOTSOCK).  Instead we need to actually create a local socket...
