The Efl.Net.Dialer.Websocket is just like other Efl.Net.Dialers: you
can dial, you can close, monitor connected/address resolved and so
on. And you can use WebSocket primitives and events such as
text_send(), binary_send(), ping() and close_request() (since
WebSockets use a close process where you should state a close
reason). See efl_net_dialer_websocket_example.c
Even if WebSocket is a message-based protocol (like "packets" from
UDP), you can use efl_net_dialer_websocket_streaming_mode_set() to
tell it to handle text or binary messages as a stream. Then all the
Efl.Io.Reader and Efl.Io.Writer APIs work as expected, see
efl_io_copier_example.c updates.
