r6223: added a bit more datagram infrastructure and the beginnings of a test

suite. The NBT-DGRAM test does a UDP/138 netlogon request, to which a
windows server sends a reply, but the windows server sends the reply
to the wrong port (it always sends to 138), so the test suite doesn't
see it.
(This used to be commit a7634625dbc944dd8256a822be290010f341a571)
