5a357a6fc5 Expose the udp/tcp listening socket w/ ListenAndServe() 
Expose the udp and tcp listening socket when ListenAndServe() is used, it seems like
plopping them on Server.Listener and Server.PacketConn would be ideal. The use case is so
that a port of zero can be used and having them exposed will allow for examination of the port
that is bound.

67945c119e A bunch of golint fixes 
The proposed vars names are a nono, because they break the API.
Things left: document each RR and zscan_rr.go has some funcky if-then-elses.

f039fd8203 Add NotifyStartedFunc field to Server 
Adds a field, NotifyStartedFunc func() to Server.

If non-nil, it is called after a server starts listening. This is useful
for synchronization purposes, for example when a daemon needs to drop
privileges after binding. Otherwise, there is no way to determine when
the server has begun listening and hardcoded delays (!) must be used or
race conditions may occur.

cd2048a15a Add Unsafe member to dns.Server 
This stops it from checking if the incoming requests have the QR bit
unset, so be careful when enabling this. This can be useful in
combination with mDNS.

Also the check for only 1 question in the question section is relaxed
to be "at least one", even without setting Unsafe!

Also update TestServingResponse to test for Unsafe vs not using Unsafe.

ebc5489482 Fix datarace in Start/Shutdown 
Add mutex and guard a 'started' boolean as well as the stopUDP
and tcpTCP channels so that 'go test -race' does not trigger.

Closes #111, closes #114

fce659ba46 Restored code when shutdown needs an exchange... 
Clients sents NULL-packet to server which helps to avoid
timeout. Timeout is still possible to encounter.
Shutdown will likely report error for those cases.

c618657d9b Dealt with race condition detector warnings: 
* stopped obvious race condition with replacing handler in
  ServingLargeResponses test
* lowered probability of other race conditions with test code
  while test server is yet activating
* fixed errmessage in Shutdown

f735bb9dcb Changed how shutdown works... 
Now stopXXX event will stop any reading on currently open
socket and terminate reading loop. No special client/server
message is required anymore.

32d6e5396e Continued removing Sleeping tests: 
* incorporated @miekg suggestions on switch vs if
* for now moved reaction to stopXXX channel messages until
  after the packet is responded to avoid client timeout in
  Shutdown (causing 2 sec. hanged thread)

Still not great how the abort logic is implemented....

f912994258 Don't relay on deadline to stop the server.
