Send one packet to the listening BadClient. Set up a 0.1 second
timeout to do re-transmits in case the packet is dropped. When two
packets have been received by the BadClient, stop sending and let
the finalDeferred's callbacks do some assertions.

The packet wasn't received quickly enough. Try sending another
one. It doesn't matter if the packet for which this was the
timeout eventually arrives: makeAttempt throws away the
Deferred on which this function is the errback, so when
datagramReceived callbacks, so it won't be on this Deferred, so
it won't raise an AlreadyCalledError.

C{'<broadcast>'} is an alternative way to say C{'255.255.255.255'}
({socket.gethostbyname("<broadcast>")} returns C{'255.255.255.255'}),
so because it becomes a valid IP address, no deprecation warning about
passing hostnames to L{twisted.internet.udp.Port.write} needs to be
emitted by C{write()} in this case.
