897f762e3c Fixed a race condition in the new request retransmission code: 
if a machine is slow or busy enough, the retransmission timer could theoretically fire
again before the first transmission has finished.  This could cause us to lose track
of whether a send is in progress or not, since that information is stored in a boolean
flag (DNS_REQUEST_F_SENDING), not a counter

28fc90e6c8 #857 was incomplete, ISC_MAGIC was not being used everwhere it should have been. 
'magic' was not being declared consistantly.
some #include <isc/magic.h> were missing from other include files.
NS_SERVER_VALID was not using ISC_MAGIC_VALID.

94baac869a 712. [bug] Sending a large signed update message caused an 
assertion failure. [RT #718]

- Resetting a message should clear the TSIG/SIG(0) sections
- Rerendering a message if the first try returned USETCP should not call
  dns_message_settsigkey() again.

Transfer-source{-v6} now take a optional port

own CVS tree will help minimize CVS conflicts.  Maybe not.

559bb1016f 265. [bug] dns_request_create() not works for TCP. 
264.   [func]          Dispatch can not take TCP sockets in connecting
                        state.  Set DNS_DISPATCHATTR_CONNECTED when calling
                        dns_dispatch_createtcp() for connected TCP sockets
                        or call dns_dispatch_starttcp() when the socket is
                        connected.
