* 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.

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!

* Added stun bootstrap functionality.
* Added in two temporary StunServers.
* Reconnect attempts are TCP only.
* enabled AUTOCONNECT and TCP Connections.
* reduced UDP keepAlive timer to 15 secs.
* made UPnP the default startup behaviour.
* Removed StunId raw printouts -> now use BinToHex()
* Unified TTLS and PERIODS in p3dhtmgr.h
* DHT bugfix (data not passed to ConnMgr).

* 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.

* minor changes to networking headers.
* addition of several virtual destructors (remove warnings)
* switched Makefiles to new system.
* added macosx specific configuration file.
* removed KadC compilation checks.

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.
