New NetSocket interface, BSD/Win implementation
Unified BSD and Winsock sockets into a single implementation of a generic NetSocket interface. This is some ground work for few network improvements: - Reuse as much code as possible between Posix and Windows. - Provide a single point of implementation for exotic sdks (consoles). - Provide platform agnostic StreamPeerTCP and PacketPeerUDP in core. - Implement connect for UDP allowing for DTLS implementation.
