Support for custom ServerSocketFactory

[buko]

Very cool project. This is sorely needed: a modern HTTP Server that doesn't use NIO.

It would be great if it were possible to use a custom ServerSocketFactory. This would not only simply the code and make it more testable but it would aksi allow the java-http project to be directly integrated into projects that work with custom Socket implementations (think P2P Overlay networks with custom TLS variants).

The Plan

Using a custom ServerSocketFactory would be straight forwards. HTTPListenerConfiguration.java would be modified to accept a ServerSocketFactory in its constructor and a public getServerSocketFactory() would be added to the class.

HTTPServerThread would be modified to accept this ServerSocketFactory in its constructor. Instead of hardcoding the creation of a new ServerSocket in the constructor (this.socket = new ServerSocket()) the HTTPServerThread should ask the ServerSocketFactory to create a new ServerSocket.

The Project would provide a DefaultServerSocketFactory and DefaultSSLServerSocketFactory.

ServerSocketFactory myCustomFactory = new MySpecializedServerSocketFactory();
HTTPListenerConfiguration listenerConfig = new HTTPListenerConfiguration(bindAddress, 8080, myCustomFactory);

HTTPServer server = new HTTPServer()
    .withConfiguration(new HTTPServerConfiguration()
        .withListener(listenerConfig)
        .withHandler(myHandler))
    .start();
