- Fixed retransmit algorithm. Much more closely matched to TCP standard: http://tools.ietf.org/html/rfc2988
- This increases retransmit timeouts, and reduces the number of packets resent.
- Added better debugging for retrans/close as separate #defines.
- Further testing is required ;)

* Added peerId to udpstunner->exclusiveMode for debugging purposes.
* added timeout for exclusive mode, this can happen if connection is lost at lower levels.

* Reduce Maximum Transmission size from 1500 -> 1000.
This is the cause of Failed Connections. It looks like UDP packets are being truncated from 1520 -> 1492 bytes.
and this is killing the TCP protocol. Windows is the main suspect. UDP packets this large are liable to get fragmented anyway.
We will start at 1000, verify that connections are okay, then start increasing this parameter.
There is up to 64 bytes of Headers (IP + UDP + Relay + TOU), so 1400 + 64 = 1464 is below the 1492 cutoff. This is the target!
* Switch to RSRandom for Sequence numbers. rand() is rubbish on Windows.
* Added code to handle Larger Packets coming in (e.g. 1500 Bytes input, now that Max Size is 1000).
NB: The code is here needs to be optimised, there are excessive numbers of malloc(), new() & memcpy(), which should be removed.

You can enable the debugging of the waiting time for a lock of RsMutex in rsthreads.h with
#define RSMUTEX_DEBUG 300
That means all locks waiting longer than 300ms are logged into the stderr.

Major changes are:
* Improvements to tcponudp library to allow multiple UdpStacks / ports, with alternative recievers.
* Resurrected the UdpStunner code, and improved it.
* Added UdpRelay code.
* Modified startup code and ssludp code to use the new tcponudp and add a stunner.
* fixed buggy rs_inet_ntoa
* fixed a bunch of apple gcc warnings. mainly for(;;); => for(;;) ;
These changes shouldn't affect libretroshare stability... those changes will follow!

* Switched off most of std::cerr output. (expect UPnP)
* moved pqi/pqidebug to util/rsdebug to allow greater usage.
* added Mutexes to logging.
* Downgraded many log messages to DEBUG.
* New Log messages for connections, dht and udp code.
* Added check for bad UDP socket.
* Added check for non-firewalled scenario.
* Increased Storage period from 1 Month to 6 Months for Links & Blog.

* Added GUI interface for auto connect state.
* Added HTTP retrieval and storage of DHT peers update.
* Added code for partial recv() from DHT peers.
* Disabled Chat/Disc/Udplayer/tcpstream debug output.
* Added Unreachable Check to connMgr.
* Added auto reconnect functions to connMgr (#define to disable).
* Restructured DHT notify code... much cleaner.
* DHT now flags out of date DHT results.
* DHT notifies ConnMgr on any results (same or diff).
* Added Fns to cleanup old udp connection.
* other bugfixes.

* Added Period and Delay parameters to connections.
- Delay is used to avoid simultaneous TCP connections.
- Period is used to regulate UDP connections.
* added Delay code to pqissl.
* added Period code to tcponudp / pqissludp.
* modified TTL modification code.
* increased SynPktRetransmit value.
* fixed retrans() timeout (one reason code wasn't working before!)
* fixed tou_close() SEGV bug.
* modified pqissludp tou_socket creation. (non permanent now).
* Modified format of peerConnectRequest() CB to make it more useful and rewrote function.
* Enabled pqissludp NetInterface.
* using Id comparision to determine Active/Passive UDP connection state.
* added #def to disable TCP connections. (for testing)
* enabled UDP connections from retryConnect() function.
* corrected EXT check in retryConnect() function.
* + lots of debug output and other stuff.

the rewrite of the retroshare core networking stack.
This check-in commits the changes to the TCPonUCP code.
This library has been significantly modified to support
multiple UDP "connections" from a single port.
This requires some trickery and a listener thread.
Code to "STUN" peers was also added.
