Fabio Alessandrelli b4e3be7519 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.
