RetroShare/libretroshare/src/pqi/pqissltunnel.h
drbob abbebf48ff Partially completed changes to implement final relay bits.
* Adding more detailed flags to each connection.
 * Cleaned up unneeded stuff from p3LinkMgr.
 * Added rswin.h includes before openssl - allows compilation using std Win OpenSSL.
 * Added getConnectFlags() to Net Base.
 * removed net_attempt and associated obsolete variables from pqissl
 * Made NetBinInterface protected in pqiperson (is this okay?)
