JsonRPC support [message #36836]

U++ now has support for JsonRpc; it is merged with existing support of XmlRpc, as two protocols are quite similar. Server simply detects the request protocol and can even handle it using the same RPC_METHOD:

http://www.ultimatepp.org/reference$Rpc$en-us.html

(of course, some methods are exclusive for one or another - XmlRpc does not have named parameters, JsonRpc can return only a single Value).

In the process, I have also introduced some new notations as demonstrated in Multiply2 method.

Mirek, I would be really grateful if you provided multi-threaded example of rpc server. I wonder what's the best way to handle multiple requests. Thank you in advance.

Do not really have time to provide tested example, but it should be something like:

for(;;) {
	TcpSocket rpc;
	accept_mutex.Enter();
	if(!rpc.Listen(port, 5))
		return false;
	accept_mutex.Enter();
	TcpSocket http;
	if(listen_socket.Accept(rpc))
		RpcPerform(http, NULL);
}

...create a reasonable work thread pool and start do this loop in all of them...

Thanks! I'll try to add the example if I succeed.
