* 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. git-svn-id: http://svn.code.sf.net/p/retroshare/code/trunk@358 b45a01b8-16f6-495d-af2f-9b41ad6348cc
