--- Merging r4753 through r4779 from /svnroot/retroshare/branches/v0.5-dhtmods

Browse source 
Merging Dht Relay improvements into the trunk. These changes should finally make relays functional.
There are still some service changes required to reduce the traffic over relays.

Summary of Changes
---------------------

 * Changed the way proxy/relay peers are selected in bdConnection. (needs more work).
 * Added LinkType to peer info in p3LinkMgr & rspeers.h interface.
 * Added getConnectionType() to p3PeerMgr. This defaults to FRIEND for the moment.
 * Provide information about Bandwidth, Transport and Peer Type via LinkType().
 * Added RateCap() to limit traffic over Relay connections.
 * Set Internal Rate to 75% of Relay Limit to account for transport overhead.
 * Added various #include "util/rswin.h" to fix compile errors with standard ssl package.
 * Removed Local variables (mConnectProxyAddr, etc) which were hiding Class Variables.
 * Cleaned up bits in pqissl.cc and p3linkmgr.cc
 * Increased UDP Relay Packet size (max transport of 1400 bytes per UDP packet)
 * Modified checkRelay() to use Low Pass Filter to calculate Relay Bandwidth.
 * Improved udprelay debugging.
 * increased (x2) Relay Lifetimes - this is so that enough useful data can be transported (1meg).
 * Added LOCALNET_TESTING code to rsinit.cc. This allows Port Restrictions to simulate firewalls.
 * more debugging and minor bugfixes.
