f4bbd3e933 Limit the concurrent connection attempts in Windows XP. Its's only a hack.
Problem:
RetroShare connects to all ssl's at once. In Windows XP there is a build-in connection limit of concurrent incomplete connections.

Quote:
"The TCP/IP stack in Windows XP with Service Pack 2 (SP2) installed limits the number of concurrent, incomplete outbound TCP connection attempts. When the limit is reached, subsequent connection attempts are put in a queue and resolved at a fixed rate so that there are only a limited number of connections in the incomplete state."

This results in a high usage of the nonepaged pool and when it runs over the limit it results in the following error in the system log:
German:  "TCP/IP hat das Sicherheitslimit erreicht, das für die Anzahl gleichzeitiger TCP-Verbindungsversuche festgelegt wurde."
English: "TCP/IP has reached the security limit imposed on the number of concurrent (incomplete) TCP connect attempts."

After a longer runtime of RetroShare and a very high usage of the nonepaged pool all connections of all running programs are lost and no new connections can be made. At the end it can cause a blue screen.

fcdd7ee113 Changes to integrate bitdht into libretroshare.
Mainly re-organising tcponudp... 
	tests->test area
	network->trash (uses libbitdht classes).
	new udp interfaces (udppeer + udpstunner)

Changes include:
	* p3bitdht: added "addReceiver() call, and more debugging. 
	* p3bitdht: added DO_IDLE flag so searches are continous.
	* p3bitdht/pqiassist: matched up Assist interface.
	* fixed pqiNetListener interface.
	* rsinit/p3connmgr: setup udp init
	* tcpstream: switched to new udp receiver.
	* added "blogs" switch in libretroshare.pro (was stopping compiling ;)
	* added "bitdht" switch in libretroshare.pro

f4331da483 Networking REWORK: Major cleanup of p3ConnectMgr.
(Sorry for the ridiculously large check-in, wants to fix lots of stuff.)

 * Reworked SSL/GPG startup to enable test harnesses
 * pqiperson: added notify of FAIL if connection method unavailable.
 * added p3tunnel to pqissltunnel init.
 * pqimonitor: added ipHistory to connect callback.
 
p3ConnectMgr Changes:
 * removed STUN system - wasn't operating correctly anyway without DHT.
 * switched to new IpAddress history data types. (removed lots of code)
 * Added Addr history for both Local and Ext addresses.
 * removed p3tunnel references in p3connmgr
 * fixed up mUseTunnelConnection flags (now used!)
 * fixed up mUseExtFinder flags (now used!)
 * added improved Net Status.
 * corrected UPNP / EXT / UDP startup. (was always UPNP).
 * fixed netReset() and netStartup().
 * removed unnecessary DEBUG code.
 * added UPNP timeout code (600 secs - why does it take so long?)
 * added improved netExtCheck().
 * removed wierd netConsistencyCheck() ... to rework.
 * corrected connect / reconnect code.

00d0d999dc * Removed list<IpAddressTimed> from callback
This functionality might need to be restored later, 
     but should be done with list<> for both Local and Remote Addrs.

2bf94b909a Reworking of networking code to enable Net Restart.
* Stun code now runs continually - to check external network state.
  * Udpsorter controls DHT stun is on/off. (via p3ConnectMgr)
  * added code to enable threads to join/restart 
  * enabled NetRestart for UDP and TCP.
  * tweaked networking code for faster startup (now ~30 seconds - can still be improved).
  * tweaked debug messages for testing networking
  * Added test for checking external IP address determination.

8b230a55cf Significant changes to aid UDP connections.
* 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.

06cb9e0121 Added a seperation between 'desired' net mode and 'actual' net mode
this is needed for accurate stunlist creation. Also added stunStatus
calls from discovery.

685182ff0b Modified DHT to notify of all possible stun peers, as it doesn't know whether we need to stun or not.
Added a Type parameter, so that the connection Mgr can determine if there is
an external port available or not.

6435357c07 Commit of the new UDP Connection methods and
the rewrite of the retroshare core networking stack.

This check-in commits the changes to the pqi code, 
and provides the majority of the improvements.

(1) Introduced new interfaces for DHT and UPnP abstraction: p3dhtmgr.h, p3upnpmgr.h
(2) Introduces abstraction for Authentication: p3authmgr.h
(3) New Connection Manager to coordinate networking code: p3connmgr.h
(4) New Configuration Manager: p3cfgmgr.h

This library has been significantly modified to support DHT synced connections
to enable connections between Firewalled Friends. The connection code has
been rewritten within a new framework, which should make extensions easier to code.

Also removed significant amount of old code relating to Tunnels, Channels etc.
This will be recycled later as higher level services that should not be
part of the core networking library.
