[feature] Shutting down websocket

[habi498]

Is your feature request related to a problem? Please describe.
I was trying to integrate websocket server inside squirrel via its api. I created function StartWebsocketServer(host, port, timeout);
Then i see that users cannot close it.

Describe the solution you'd like
I like to have a function ws_shutdown() which will shut everything down, stop the threads, close the sockets.

Describe alternatives you've considered
I considered alternative as manually close port on ws.c

Hi @habi498,
This is a long standing feature requested for a few years, since issue #31 at least.

I haven't implemented it yet because I'm not sure on how to do it: whether I should gracefully close each client connection, or if it's 'ok' to just abruptly close connections. Since wsServer is advertised as RFC 6455-compliant, these are questions that concern me a bit about how to approach this.

I still want to implement it, and I want to see how other big and reference libraries do it, if most of them just abruptly close the connections, I won't have a problem doing that either =).
