Fixed interfaces for UPnP.
Some further tweaks to get TCP connections working again:
- hiddenNode issue in p3peers.cc
- fixed socklen_t for bind() and connect() calls.
- initialise addr to IPv4 for netmgr.
- change netAssist (Upnp) interfaces.
Still todo: tou address functions, test UDP functionality.
