Fabio Alessandrelli 1ef9e9ef6a Properly accept wildcard when binding IPv4 socket. 
Also never return null for is_ipv4 to avoid crashes due to engine bug.
(better to get an error and a broken socket then seeing your game crash)

Fabio Alessandrelli c37442ef00 Fix Winsock UDP ECONNRESET/ENETRESET bug 
Since Windows 2000:
Calling recv/recvfrom when an ICMP reply was received from a previous
send/sendto, may result in a WSAECONNRESET error.

Since Windows Vista(?)/Windows Server 2008:
Calling recv/recvfrom when an ICMP reply was received from a previous
send/sendto, may also result in a WSAENETRESET error.

Both those features are disabled by this commit using disabling
SIO_UDP_CONNRESET and SIO_UDP_NETRESET on newly created UDP sockets.

Fabio Alessandrelli 479d4fb741 Detect POLLERR revents too in NetSocketPosix. 
Usually indicate an RST was received by a TCP socket.

Fabio Alessandrelli a15db2d2b6 Use select instead of WSAPoll on Windows. 
WSAPoll is broken by design.
It was announced as the new way to introduce compatibility to posix
sockets, their implementation was broken, and they decided not to fix it.

Fabio Alessandrelli 01c3c1a07b Properly initialize Winsock on startup 
Also fix typo in _get_last_error which caused Winsock connect to fail.

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.
