Imprevement to 'Emulated POSIX TCP Sockets over WebSockets' to work with Socks4/5 proxy .

[Maksons]

Hello to all,

Would like to share idea of adding connection pass to Socks 4 or 5 proxy.
It's look like should not be hard, just on first message add extra header with destination IP/Port/protocol and on response to check connection result (connected/bindded) and then report status on POSIX socket.
On PC side same 'websockify' + Socks proxy.
It will give option to connect/listen for multiple emulated sockets in web application not single one.
