Merged socket development branch:

* Fixed bug report (Duane Voth: Python sockets test application not working) by starting the receive operations when a connection is established!
* Increased performance by extending the idle loop into the network stack with the Poll call.
* Added support for TCPv6 (SOCK_STREAM) and UDPv6 (SOCK_DGRAM).
* Added support for getaddrinfo and getnameinfo calls.
* Moved application PCD values into AppPkg
